Nephrocalcinosis treatment. Nephrocalcinosis - what causes metabolic disorders in the body

The kidneys are an important organ of the urinary system, with the help of which harmful and waste substances, toxins are removed from the body.

It is not surprising that they are often exposed to various diseases, one of which is nephrocalcinosis.

Calcifications are dense deposits that look like a stony sediment consisting of calcium salts. Similar deposits can occur in many organs: lungs, uterus, thyroid gland, etc.

general information

If we consider these formations with respect to the kidneys, then they can form both in itself and on the walls of its tubules.

Crystallization of calcium salts causes the gradual death of the cells of the organ located under the sediment, resulting in the formation of scar tissue.

Sclerotic and inflammatory processes of this nature almost always lead to chronic renal failure.

Reasons for the appearance

The main factor leading to the formation of deposits is a metabolic disorder, in particular, calcium and phosphorus in the body.

Most often it is hypercalcemia - too high calcium in the blood, and hypercalciuria - the excretion of this element in the urine.

In such a situation, the body simply can not cope with the load. Depending on the cause and clinical picture of the disease, 2 types are distinguished:

• primary, which affects a generally healthy organ;
• secondary, in which the precipitate is formed in conjunction with pathological changes in the kidney.

The following factors lead to the primary form:

• the intake of a large amount of calcium into the body, which may occur due to a special diet or certain medications, as well as certain diseases;
• excessive levels of vitamin D, which affects calcium levels;
• various types of bone lesions, such as osteoporosis, tumors in the bones, etc.;
• some malignancies;
• improper excretion of calcium, the cause of which may be hormonal diseases or diseases of the kidneys themselves;
• hyperparathyroidism;
• sarcoidosis.

The cause of secondary nephrocalcinosis is:

• poor blood circulation in the kidneys caused by atherosclerosis, thrombosis, etc.;
• organ damage by radiation;
• intoxication caused by mercury salts;
• regular intake of certain drugs - thiazide, ethacryne, sulfonamides, etc.

Thus, this disease can be directly caused by disorders in the kidneys themselves, or by extrarenal causes.

Clinical picture

Symptoms of the disease differ in primary and secondary nephrocalcinosis.

At the initial stage, the formation of calcifications is very difficult to suspect, since with a slight lesion of one kidney, the second takes on part of the load. Thus, there are no pronounced symptoms, but still they are:

• general weakness and fatigue, decreased stamina;
• dehydration, manifested in thirst, dizziness, discoloration of urine before, etc.;
• constipation;
• itching and dry skin;
• emotional tension;
• trembling of the limbs, convulsions;
• joint pain;
• possible increase in blood pressure.

These symptoms may indicate an excess of calcium in the blood. When identifying the following signs, we can talk about the defeat of the organ itself and the beginning of the secondary form. During this period, the cells of the kidney tissue die and calcium is deposited in the deeper layers.

The tubules of the kidneys are clogged, which leads to impaired renal function. At this time, the connective tissue grows and the parenchyma is replaced by scar tissue. This process calls:

• pain in the lumbar region and;
• decrease in the specific gravity of excreted urine -;
• the volume of urine excreted increases sharply;
• , and erythrocytes.

In addition, this disease causes other kidney diseases.

Possible Complications

Violation of the functioning of the excretory system in most cases provokes the development of inflammatory processes, pyelonephritis and. In addition to disorders in the kidneys themselves, nephrocalcinosis also has a negative effect on neighboring organs.

In particular, on the bladder, where calcium deposition can also begin. Because of this, the water-salt balance is disturbed.

In most cases, chronic renal failure develops quite quickly. Calcifications in the plural can talk about malignant or benign neoplasms. They themselves can become the cause of development.

How to Diagnose

Often, the onset of the disease is not accompanied by any symptoms, and nephrocalcinosis is detected by chance, most often during an ultrasound scan.

Therapy Methods

The whole process of treating nephrocalcinosis involves, first of all, the elimination of all the causes that cause the deposition of calcium salts, as well as therapy for the treatment of concomitant kidney diseases and their symptoms. Surgical intervention in this case is ineffective.

Removing the cause

First of all, it is necessary to take measures to reduce the level of calcium in the blood. To do this, a certain diet is observed and lifestyle changes.

More time should be devoted to sports, as it provokes the outflow of urine, which reduces the time for toxins to remain in the body.

A special place is occupied by a diet corresponding to. It helps to remove toxins from the body. It consists in refusing or significantly reducing foods that contain calcium and vitamin D. These are foods such as:

• sesame and sunflower seeds, poppy, halva;
• milk and dairy products: cheeses, cheese, cottage cheese and sour cream, condensed milk;
• walnuts and nutmeg, almonds;
• black bread, bran and wheat flour, oatmeal;
• garlic, cabbage, dill and parsley.

At the same time, salt should also be excluded from the diet. Desirable for consumption are lemon and its acid, cumin and cilantro, cinnamon. Diuretics can be prescribed, but do not increase the volume of daily fluid.

Symptomatic treatment

Calcium levels can also be controlled with certain medications. For this, solutions of sodium bicarbonate and citrate are used. In some cases, sodium chloride or potassium aspartate are indicated. B vitamins are a must.

Carry out the therapy of diseases associated with nephrocalcinosis: renal failure, urolithiasis and others, with the help of anti-inflammatory and analgesic drugs. In severe cases, even a kidney transplant is used.

Features for kids

Nephrocalcinosis in children usually develops much faster than in adults. The cause is usually congenital disorders of the kidneys or metabolism. In addition, one of the reasons may be the transfer of an infant to cow's milk with herbal supplements.

In addition, the children's body can not fight this disease for a long time.

Therefore, at the first suspicion, you should immediately hospitalize the child and conduct a thorough examination.

Treatment is carried out almost identical to the conventional one. The only difference is in the treatment of concomitant diseases.

Forecast and prevention

The prognosis directly depends on the stage of the disease and the effectiveness of treatment. If nephrocalcinosis is detected at the very beginning of its development, then the prognosis with proper treatment is positive. This means that it is possible to maintain the organ and its function at the proper level.

In advanced cases, serious complications and consequences occur, which require hemodialysis and, possibly, organ transplantation. A fatal outcome is also possible.

As such, prevention against the deposition of calcium salts does not exist. It is also important to drink water and exercise.

Do not take calcium supplements without a doctor's prescription. One of the important points is the intensive treatment of inflammatory and infectious diseases of the urinary system.

It is important to monitor the state of health, and at the slightest suspicion, consult a doctor.

Nephrocalcinosis- a disease that belongs to the group of calcifications. Calcinosis, also known as calcareous degeneration, is a form of pathology of calcium metabolism in the body: calcium salts precipitate from liquids (they were dissolved in liquids) and precipitate, being deposited in the interstitial tissue and in cells.

Nephrocalcinosis is a variant of metastatic calcification, in which calcium salts are diffusely deposited in the kidney tissue, which causes their inflammatory and sclerotic changes and.

Types of nephrocalcinosis according to clinical manifestations:

• primary
• secondary

In the primary, no changes in the kidneys are observed, and in the secondary, kidney pathology occurs along with the processes of precipitation of calcium salts. Nephrocalcinosis can occur, for example, in alkaline milk syndrome or Burnett's syndrome. It is likely in children who are being switched from natural feeding to cow's milk with herbal supplements. Read more about the reasons below.

What provokes / Causes of Nephrocalcinosis:

Among the causes of primary nephrocalcinosis are:

• conditions in which too much calcium enters the body (familial and idiopathic neonatal hypercalcemia, Burnett's syndrome, Lightwood-Fanconi syndrome, sarcoidosis, excessive intravenous administration of calcium salts)
• conditions in which calcium is mobilized from the bones (tumors of bones and some organs, multiple myeloma, tumor metastases in the bone, postcastration and corticosteroid osteoporosis, postmenopausal osteoporosis, multiple bone fractures, Paget's disease, neuroplegia, immobilization, thyrotoxicosis)
• hypophosphatasia (impaired calcium binding in the bones)
• oxalosis, calciphylaxis, in which calcium is deposited in tissues that are not normally needed there
• tubulopathies and various diseases that occur with acidosis (chronic tubular acidosis of Buttler-Albright, transient tubular acidosis of Lightwood, Lowe's oculocerebrorenal syndrome, glucose-phosphate aminoaciduria de Toni-Debre-Fanconi, hyperchloremic acidosis, )

Secondary nephrocalcinosis: causes

Among the most likely reasons are:

• radiation nephrosclerosis
• ischemic cortical necrosis of the kidneys
• abuse of sulfonamides, thiazide diuretics, phenacetin, ethacrynic diuretics, anthranil diuretics
• uncontrolled use
• mercury salt poisoning

Nephrocalcinosis can be caused by renal and extrarenal disorders of the acid-base balance. This is mainly metabolic and respiratory acidosis, in rare cases it is metabolic alkalosis. With these diseases, the level of calcium in the blood rises, its excretion in the urine increases. The degree of calciuria can be a maximum of 400-600 milligrams in 24 hours.

Pathogenesis (what happens?) during Nephrocalcinosis:

The pathogenesis of calcifications

The matrix for calcium salts inside cells is lysosomes and mitochondria. Outside the cells, these are collagen and elastic fibers plus glycosaminoglycans of the main substance of the interstitial tissue. Calcium salts may be deposited in the form of grains, limestone pockets, which are more or less common in different cases. In areas with lime, bone tissue can form, and around it there will be inflammation and a fibrous capsule.

Local and general factors play a role in the pathogenesis of calcinosis. Therefore, the forms of calcification, in addition to the criterion of the location of calcifications, are distinguished according to pathogenetic factors. Calcification can be metastatic, metabolic and dystrophic, which is also known as (petrification).

Pathogenesis of nephrocalcinosis

An abnormally large influx of calcium occurs to the kidneys, it accumulates in the epithelial cells of the human kidneys. When there is too much intracellular calcium, cell dystrophy occurs. The deposited calcium enters the interstitial space or into the lumen of the tubules. In this process, cylinders are formed that block the tubules, so they dilate and atrophy. Salt deposits in the interstitium cause a lymphoproliferative reaction, then it occurs.

With nephrocalcinosis, infection and the formation of stones occur, because this disease becomes the source of pyelonephritis and / or hydronephrosis. The pathogenesis of primary nephrocalcinosis in children and adults is characterized by the fact that the proximal nephron is first affected, and the glomerulus and distal nephron are affected later. If nephrocalcinosis is secondary, then calcium is deposited simultaneously in the distal nephron.

Symptoms of Nephrocalcinosis:

With nephrocalcinosis, there is usually an underlying disease. Therefore, two groups of symptoms appear at once, as well as concomitant hypercalcemia. Calcium toxicity causes the following symptoms:

• fatigue
• general weakness
• vomit
• dry skin
• thirst
• constipation
• joint deformity
• joint pain
• mental instability
• keratoconjunctivitis
• seizures
• shortening of the duration of systole on the electrocardiogram

With kidney damage, when the transport of substances in the tubules is disrupted and their sensitivity to antidiuretic hormone is lost, the following occur:

• isosthenuria
• polyuria
• possible attacks of renal colic (with the passage of stones)
• pain in the lumbar region

Often there are persistent changes in the urinary sediment, it contains a large number of bacteria, leukocytes, salt casts and erythrocytes. Later fix hypostases, arterial hypertension. In this period, as a rule, symptomatic and laboratory signs of kidney failure are already manifested.

Complications:

• Chronic renal failure
• Obstructive uropathy
• Stones in the kidneys

Diagnosis of Nephrocalcinosis:

Diagnosis of nephrocalcinosis at the stage of its appearance is based on the information obtained from the basis of a puncture biopsy of the kidney. Such a method as plain radiography is relevant only in severe cases, when calcification of the renal pyramids is significantly expressed.

To approximately determine the degree of calciuria, diagnosticians sometimes use the Sulkovich test. To clarify the cause of the disease, the patient's urine and blood are examined for the content of calcium and phosphorus, the activity of parathyroid hormone in the blood, alkaline phosphatase is determined. Urinary excretion of hydroxyproline, acid-base balance, clearance and phosphate should be determined.

Nephrocalcinosis in the diagnosis is distinguished from a spongy kidney, in which the cystic spaces are filled with a condensate of calcium salts.

Treatment for Nephrocalcinosis:

It is necessary to eliminate the cause of calcium metabolism disorders in the body as soon as possible. With severe dehydration, infusions are made of a solution of bicarbonate or sodium citrate, potassium citrate and aspartate in case of acidosis, and in case of alkalosis, infusions of sodium chloride and ammonium are made.

If hypercalcemia is moderately severe, the patient is advised to follow a diet with foods that contain little or no calcium. Vitamin B6 and an infusion of magnesium sulfate solution are attributed. The treatment of acute hypercalcemia consists in the infusion of a solution of magnesium sulfate, sodium phosphate, sodium EDTA. Doctors may prescribe an injection or prednisone.

Treatment of progressive renal failure is mandatory with hemodialysis. It is important to adequately treat pyelonephritis, which causes progression of kidney failure. In secondary nephrocalcinosis, it is important to identify and treat the underlying disease, which acts as an etiological factor.

Forecast with effective treatment at the beginning of the disease is good. An unfavorable prognosis in patients with progressive nephrocalcinosis, because in advanced cases, uremia occurs, threatening the health and life of the patient.

Prevention of Nephrocalcinosis:

• You should get the optimal amount of calcium (no more and no less) with daily meals.
• Do not take calcium supplements without a doctor's prescription.
• It is important to treat on time.
• If suspicious symptoms and any health problems appear, you should immediately contact a general practitioner, family doctor or a highly specialized doctor.

Calcifications in the kidneys are formed due to impaired metabolism in the body. Pathology is reduced to the formation of a dense layer of calcium salts on the dead tissues of the parenchyma of the organ. Nephrocalcinosis is recorded in people of any age and gender. Timely and adequate treatment can prevent the development of chronic renal failure.

Nephrocalcinosis is usually divided into primary and secondary. The primary form is directly related to the violation of the calcium-phosphorus balance. Calcium deficiency in the body due to its leaching in the urine is just as dangerous as its excess. This condition can be provoked by:

1. Violation of the process of removing the trace element from the body. The cause is hormonal disruptions, kidney disease.
2. The body receiving a large amount of calcium while taking medications or when unprofessional compiling a diet menu.
3. Increased vitamin D content.
4. Tumor formation of the parathyroid glands. Increases the production of parathyroid hormone, which is necessary for the absorption of calcium by the body. The result of excessive activity is hypercalcemia.
5. Damage to bone tissue, provoking the ingress of calcium salts into the blood. The main cause is bone metastases and osteoporosis.
6. Disruption of the thyroid gland, which produces the hormone calcitonin. Its deficiency leads to the leaching of the microelement from the body with urine.
7. A kidney disease in which the renal tubules are unable to excrete calcium ions into the urine. These pathologies include congenital and acquired tubulopathies.

The secondary form is caused by ischemic necrosis of the kidney tissue. It is promoted by:

• mercury intoxication;
• taking thiazides, phenacetin;
• impaired blood circulation in atherosclerosis, embolism of the renal arteries;
• irradiation.

Secondary nephrocalcinosis can be cortical, developing with acute necrosis, or nodular, which is considered the most complex.

Symptoms and Diagnosis

Symptoms of the disease may not appear in the absence of obstruction of the ureter. The asymptomatic course of the disease is also observed in cases where there is no effect on the filtration capacity of the kidneys.

Common symptoms of nephrocalcinosis are reduced to fatigue, problems in the digestive tract, constipation, dizziness, malaise, loss of appetite, sleep disturbance. Large formations provoke the appearance of severe pain. Pathology is most pronounced with a large number of large-sized calcifications. Patients complain of pain in the lumbar region, intense thirst, frequent urination. In patients, swelling of the extremities, dehydration of the body, and yellowness of the skin are recorded. Edema differs from those caused by pathologies of the cardiovascular system, warmth and the absence of a bluish tint. The accumulation of toxins in the urine gives rise to bad breath. In advanced cases, the pathology causes an increase in blood pressure and proteinuria.

The effectiveness of treatment depends on the time of detection of the disease. At the first stage of development, microcalcifications cannot be determined using radiography or ultrasound. The most reliable method of diagnosis in this case is a puncture biopsy. A specialist for making a diagnosis also needs to study the results of a general and biochemical analysis of blood, urine.

Ultrasound is able to detect calcifications in the kidneys at a stage when it is still possible to preserve the function of the organ with the help of adequate treatment. In this case, specialists need to conduct additional studies to exclude a spongy kidney. Radiography is used for advanced forms of pathology. Each of the methods is necessarily supported by the results of laboratory studies on the content of calcium in the blood and urine, the concentration of vitamin D and parathyroid hormone.

The danger of calcifications

Calcifications cause disturbances in the functioning of the kidneys, which affects the functioning of the entire urinary system. Water-salt imbalance in combination with impaired excretory function of the body provokes the development of various pathologies of internal organs. Multiple deposition of calcifications may be associated with the development of a malignant neoplasm. The movement of calcifications causes the risk of their penetration into the bladder.

A constant supply of calcium makes the kidneys work harder. Not being able to "rest" after increased loads, the internal organ begins to allow the accumulation of the microelement in the parenchyma. As soon as the amount of calcium in the epithelial cells of the organ becomes pathologically high, the process of their death begins with the formation of deposits in the tubules. Gradually, small cylinders are formed that can completely clog the tubules, excluding the possibility of their further functioning. The process is accompanied by the growth of connective tissue, which replaces the parenchyma. The cyst usually does not exceed a size of 5 mm, but causes the development of renal failure, nephrosclerosis, wrinkling of the kidney. Changes create favorable conditions for the development of various infectious and inflammatory diseases. The most common are urolithiasis and pyelonephritis. Attached pathologies become an additional blow to health, acute renal failure may develop.

Another type of complication of pathology is uropathy. In this case, there is a reverse flow of urine, which, unable to move through the urinary canals, returns to the kidneys.

In children, it takes much less time for complications to develop, so it is necessary to start treating the disease at the earliest stages.

Treatment of pathology

The principle of treatment of the disease does not depend on whether calcifications are found in the kidneys of a child or an adult. Therapy is aimed at reducing the concentration of calcium in the blood and restoring metabolism. Methods of therapy are selected in accordance with the severity of the disease. Doctors use complex treatment, consisting of a special diet, lifestyle changes, drug therapy and hemodialysis. Appeal to surgical intervention occurs only in extreme cases in the treatment of serious complications of pathology. The fight against nephrocalcinosis with a scalpel is considered ineffective.

If calcifications were detected at an early stage, then it is enough for the patient to adhere to a salt-free diet. Gradually, all signs of the disease disappear without any additional measures. The need for hemodialysis occurs with severe kidney damage. In other cases, medical treatment is used. Each patient should receive additional advice from an endocrinologist and gastroenterologist before prescribing and starting medication. If necessary, the nephrologist (or urologist) will make an amendment to the list of prescribed medicines.

Medical treatment

Treatment involves the mandatory intake of B vitamins and injections of a solution of bicarbonate and sodium citrate. The solution helps to remove hazardous substances from the body. When acidosis (acidification) of the body is detected, the patient is prescribed potassium citrate. If the opposite effect is observed with alkalosis (balance shift towards an alkaline environment), sodium chloride is prescribed. The onset of a crisis or the threat of cardiac arrest against this background requires immediate hemodialysis.

Inflammatory processes and associated pathologies do not allow the body to completely get rid of calcifications. A stable increase in blood pressure involves the use of special drugs and observation by several specialists at once.

With pyelonephritis and urolithiasis, it often becomes necessary to stop the pain syndrome, suppress the inflammatory process and stimulate the kidneys. For this purpose, Rifampicin and Voltaren as anti-inflammatory drugs, Papaverine or No-shpa as antispasmodics and Curantil, which has a beneficial effect on renal blood flow, can be included in the treatment course.

Diet based table number 7

For a speedy recovery, the patient needs to restore the water-salt balance. A diet for calcifications in the kidneys involves eating 5 times a day in small portions. The daily rate of fluid intake is reduced to 800-1000 ml. A classic example of a menu for the day is the option:

1. Milk porridge with butter, a slice of salt-free bread and a cup of tea for breakfast.
2. Omelet, cottage cheese or fruit for a second breakfast.
3. Vegetarian soup, mashed potatoes and steamed veal for lunch. As a drink, you can drink tea or fruit juice.
4. For an afternoon snack, a vegetable salad and a casserole are appropriate.
5. Dinner is limited to a bun with a glass of kefir.

At the time of treatment, a person will have to exclude nuts, cheeses, parsley, cabbage, legumes, condensed and fresh milk, sour cream, garlic, halva from the diet. The diet is designed to restore the body's defenses and remove all harmful substances, so the exclusion of certain foods should not be taken as a sentence. The patient can consume a large number of products that are not subject to restriction, which allows experimenting with dishes. Diets should be followed until the attending physician confirms complete recovery.

Treatment of pathology requires a sharp change in lifestyle and stretches for a long time. Regular medical examination, timely and high-quality treatment of all kidney pathologies under the supervision of a specialist helps to avoid the development of the disease.

Causes of nephrocalcinosis Regulation of calcium metabolism in the body What happens to the kidneys with nephrocalcinosis? Clinical manifestations How to establish the diagnosis? Principles of treatment

Nephrocalcinosis or kidney calcification is the deposition of calcium salts in the parenchyma of an organ, which has a diffuse (common) character and is accompanied by the development of inflammatory, sclerotic processes in the kidney tissue, which can ultimately lead to chronic renal failure.

Causes of nephrocalcinosis

Depending on the causes of development, there are 2 types of kidney calcification:

primary, which develops in a healthy kidney; secondary, which affects the pathologically altered organ.

Primary nephrocalcinosis

This is not an independent disease, this pathological condition is a symptom of diseases that are accompanied by disorders of calcium-phosphorus metabolism with the development of hypercalcemia (increased calcium concentration in the blood) and hypercalciuria (active excretion of calcium in the urine). The most common cause of primary kidney calcification is:

excessive intake of calcium ions in the body (diet enriched with this element, drugs with calcium); lesions of bone tissue with the release of calcium from its depot (bones) into the blood (bone tumors, osteoporosis, bone metastases); malignant tumors of various localization, which have the ability to synthesize parathyroid hormone; violation of calcium excretion from the body (hormonal diseases, kidney pathology); kidney diseases in which the function of the renal tubules, which are responsible for the release of calcium ions into the urine, is impaired (congenital and acquired tubulopathies); hypervitaminosis D (leads to hypercalcemia and related consequences); sarcoidosis; hyperparathyroidism (increased secretion of parathyroid hormone by the parathyroid glands), in 90% of cases this disease is caused by a hormone-producing tumor of the gland.

Secondary nephrocalcinosis

The reasons that contribute to the development of secondary calcification of the kidneys include:

necrosis of kidney tissue; circulatory disorders in the organ (atherosclerosis, thrombosis, embolism of the renal arteries); radiation damage to the kidneys; mercury intoxication; continuous use of sulfa drugs, phenacetin, thiazide, anthranilic, ethacrine diuretics, amphotericin B.

Regulation of calcium metabolism in the body

Normally, calcium metabolism in the body is regulated by 3 hormones: vitamin D, parathyroid hormone and calcitonin. The reservoir of this element is the bones, where calcium is stored and, if necessary, enters the blood.

Vitamin D enters the body with food and is formed in the skin under the influence of ultraviolet radiation. It increases the concentration of calcium in the blood by:

activation of calcium absorption from food in the intestine; increase the reabsorption of ions in the kidneys; increased resorption of calcium from bones.

Accordingly, with a pathology such as hypervitaminosis D (an excess of vitamin in the body), hypercalcemia will also develop with calcification of the kidneys and other organs.

Parathyroid hormone is produced in the parathyroid glands. Its synthesis is regulated by the concentration of calcium in the blood - with a high content of calcium in the blood, the synthesis of parathyroid hormone decreases and vice versa. Parathyroid hormone increases the concentration of calcium in the blood in the following ways:

leaches calcium from bones; increases the reabsorption of the element in the kidneys; activates the synthesis of vitamin D; enhances the absorption of calcium from food in the intestines.

Leaving the physiological mechanisms of the influence of parathyroid hormone, with an increase in its concentration, hypercalcemia and nephrocalcinosis develop.

Calcitonin is a hormone produced by the thyroid gland. The function of the hormone is to reduce the concentration of calcium in the blood by:

suppression of the process of calcium resorption in bone tissue; in the kidneys inhibits the reabsorption of ions, which leads to an increase in the excretion of calcium in the urine. general weakness, fatigue, inability to concentrate, drowsiness, depression; skeletal muscle weakness, muscle and joint pain, bone pain; nausea, vomiting, spastic abdominal pain, constipation, lack of appetite, pancreatitis; thirst and dry mouth; cardiac arrhythmias, pain in the region of the heart, hypertension, during examination, a shortening of the QT interval is found on the ECG, on ultrasound - calcification of the heart valves and blood vessels, with severe hypercalcemia - cardiac arrest; signs of urolithiasis, frequent pyelonephritis, pain in the lumbar region, signs of progressive renal failure.

When kidney damage is already irreversible, edema, increased blood pressure, proteinuria and other signs of terminal renal failure appear.

How to establish a diagnosis?

It is important! The earlier the diagnosis of nephrocalcinosis is established, the greater the chance of saving kidney function. At an early stage of the disease, the only diagnostic method is a puncture biopsy of the kidney, since the changes are not yet visible either with radiography or ultrasound.

Radiographic signs of nephrocalcinosis appear only in advanced cases, when most of the parenchyma of the organs is pathologically changed. Ultrasound will also help to suspect calcification, but the scans are very similar to such a congenital pathology as a spongy kidney, which requires differential diagnosis.

Methods such as determining the concentration of calcium in the blood and urine, the concentration of parathyroid hormone, vitamin D, a general and biochemical analysis of blood, urine, and an examination aimed at finding the root cause of hypercalcemia will also help in establishing the diagnosis.

Principles of treatment

Treatment of kidney calcification, first of all, should be aimed at eliminating the cause of this pathological condition.

In order to correct the level of calcium in the blood, apply:

the introduction of solutions of citrate and sodium bicarbonate; aspartate and potassium citrate in acidosis (shift of the acidic balance of the blood to the acid side) and sodium or ammonium chloride - in alkalosis (to the alkaline side); a diet with a restriction of calcium intake in the body; B vitamins; the abolition of drugs that contain calcium; hemodialysis with hypercalcemic crisis and the threat of cardiac arrest; therapy of concomitant pyelonephritis, urolithiasis, high blood pressure, renal failure; at the terminal stage of renal failure, treatment is carried out by program hemodialysis or kidney transplantation is performed.

The prognosis for nephrocalcinosis depends on the stage of the disease and the treatments that are used. Most often, at the initial stages of the pathology, with timely diagnosis and effective, intensive treatment, the patient's condition improves, kidney function is restored, and the organ can be saved. But with the progression of calcification and the development of renal failure, severe complications are possible, which, if not treated with hemodialysis or kidney transplantation, lead to death.

Renal calcification is a diffuse deposition of calcium salts in the tissues of the kidneys, accompanied by proliferation of connective tissue, inflammation and renal failure.

Disease pathogenesis

There are two types of kidney calcification:

primary (development of a pathological process in previously healthy kidney tissue); secondary (damage to already necrotic tissue).

Primary nephrocalcinosis (nephro - kidney; calcification - deposition of calcium salts) develops as a result of a violation of phosphate-calcium metabolism. Kidney calcification can frolic due to congenital or acquired kidney diseases, in which the main work of the tubules is disrupted (various tubopathies).

Most often, this kind of pathology occurs with vitamin D hypervitaminosis, osteoporosis, cystanosis and hyperparathyroidism.

Secondary nephrocalcinosis develops with ischemic necrosis, renal sclerosis, poisoning with mercury salts, the use of amphotericin B and ethacrine diuretics. Also, the development of secondary calcification contributes to the violation of acid-base balance.

A large amount of calcium supplied to the kidneys accumulates in the cells of the renal epithelium. When a certain amount of this substance is exceeded, cell dystrophy occurs and during this period calcium begins to move into the lumen of the tubules or the interstitial space. The resulting cylinders block the lumen of the tubules, thereby contributing to the development of atrophy and dilatation. Such a process is further accompanied by the development of kidney sclerosis or stone formation.

In primary nephrocalcinosis, calcium is primarily deposited in the proximal nephron. With the further development of the disease, it can be deposited in the distal and glomeruli. But with secondary nephrocalcinosis, calcium is deposited simultaneously in all parts of the nephron.

Symptoms and clinical picture

In most cases, with nephrocalcinosis, patients complain of general malaise, weakness, fatigue, itching, joint pain, frequent constipation, seizures and mental disorders.

During the examination of the patient and evaluation of the results of the examination, the doctor can detect various kinds of changes:

shortening of the duration of systole on the ECG; polyuria, isosthenuria, polydipsia; pain in the lumbar region during palpation; urolithiasis; proteinuria; swelling of the limbs; arterial hypertension; kidney failure.

Diagnostics

Diagnosis of kidney calcification is carried out, first of all, from examination and questioning of the patient. To clarify the diagnosis, the patient needs to pass the necessary tests and undergo an X-ray examination.

It is important! At an early stage in the development of nephrocalcinosis, an accurate diagnosis is made on the basis of a kidney puncture biopsy taken. A kidney biopsy is the most rational diagnostic method that allows you to objectively assess the degree of development of the pathology, choose the right method of treatment and avoid side effects.

In advanced stages, the localization of accumulated calcium can be detected using a plain radiography of the kidneys. The established diagnosis is based on the following signs:

the presence of calcium salt in the parenchyma; diffuse intrarenal distribution of calcium.

To clarify the cause of the development of this pathology, a biochemical analysis of urine and blood is prescribed. With the help of these tests, the presence of calcium and phosphorus, parathyroid hormone in the blood, alkaline phosphatase activity, excretion of hydroxyproline in the urine and acid-base balance are determined.

Treatment of kidney calcification, first of all, should be aimed at eliminating the cause of the violation of phosphate-calcium metabolism in the human body.

In the earlier stages of the disease, treatment may be as simple as a properly adjusted diet with limited calcium and vitamin B supplementation.

The imbalance of calcium and magnesium plays a leading role in the development of kidney calcification. Therefore, to normalize the process of assimilation of these substances, experts prescribe the introduction of a solution of sodium and magnesium sulfate.

In the most severe stages of the disease, hemodialysis or kidney transplantation is performed. Hemodialysis is an extrarenal blood purification, which is an efferent method of extracorporeal detoxification of the body.

In severe dehydration, infusions of bicarbonate or sodium citrate solutions are indicated, and in alkalosis, ammonium solutions.

The prognosis depends on the stage of the disease and methods of treatment. Most often, at the very beginning of the disease, with effective treatment, the patient's condition improves, and the functional state of the kidneys is restored. With the progression of kidney calcification, severe complications and the development of uremia are possible.

Many different factors of the environment in which humanity lives, provokes the occurrence of metabolic changes in the body. As a result of such violations, new compounds are formed, which eventually accumulate in certain organs and lead to the development of various diseases.

Renal nephrocalcinosis - what is it?

Nephrocalcinosis is a pathological inflammatory process characterized by diffuse precipitation of calcium phosphate salts on the walls of the renal tubules or in their parenchyma itself.

This disease often develops as a result of a violation of calcium metabolism in the human body for any reason. Calcium salts crystallize and are deposited in the tissues of organs, mainly in the renal tissue, sclerosis (scarring) develops. Nephrocalcinosis in almost all variants of development leads to renal failure (chronic).

Types of pathogenetic aspects of the development of the disease

There are two types of nephrocalcinosis, which are distinguished by etiological factors:

With the development of sclerosis and the deposition of calcium elements on the previously unchanged renal parenchyma, one can speak of the primary form of nephrocalcinosis; In the secondary form of the disease, the sediment is fixed on the scar tissue of the kidney. This type of nephrocalcinosis begins simultaneously both from the cortical part and from the epithelium of the tubules.

According to the localization of calcifications in the kidney, the disease is classified:

Cortical nephrocalcinosis (calcium deposits are formed mainly in the cortical layer of the kidney); Medullary (calcium precipitates in the areas of the renal pyramids).

The formation of calcium phosphate and its fixation in the kidneys is due to hypercalcemia and hypercalciuria (increased calcium concentration in the blood and urine). Due to the increased load, the kidneys do not cope with their basic functions; sediment is fixed inside the epithelial cells of the renal tubules.

Then dystrophic changes in the epithelium occur, calcium salts pass into the interstitial part of the renal tissue or into the lumen of the tubules, blocking them (cylinders). In the parenchyma, metastatic foci of calcium fixation provoke the activation of the immune system, which leads to the replacement of normal kidney tissue with connective tissue.

Inflammatory changes occur due to blockage of the tubules of the kidneys and disruption of the normal passage of urine. Often as a complication, pyelonephritis occurs, as well as hydronephrosis of the kidney.

Deposition of calcium salts in the kidney

For the prevention of diseases and the treatment of kidneys, our readers advise the Monastic Collection of Father George. It consists of 16 useful medicinal herbs that are extremely effective in cleansing the kidneys, in the treatment of kidney diseases, urinary tract diseases, and in cleansing the body as a whole.

Causal factors in the development of primary nephrocalcinosis:

Increasing the intake of calcium in the human body. The cause may be congenital tubulopathy in children, neonatal nephropathy, Burnett's syndrome and Lightwood-Fanconia, some other diseases. Pathological conditions in which calcium is strongly excreted from the bones: osteoporosis, hormonal imbalance (hyperparathyroidism), metastatic processes in the bone system and multiple myeloma, increased levels of thyroid hormones. Increasing the level of vitamin D in the body, which is responsible for increasing the concentration of calcium in the blood.

Reasons for the development of a secondary form of nephrocalcinosis:

Acute violation of the blood supply to the cortical layer of the kidneys. Radiation damage to the kidneys. Toxic effects on the body of mercury. Overdose or use of excessive amounts of phenacetin, sulfonamides. Abuse of various diuretics. Violations associated with changes in the acid-base balance of the blood.

Signs and symptoms

Nephrosclerosis and precipitation of calcium salts in the renal parenchyma can have many different clinical manifestations.

First of all, there are signs of calcium intoxication of the body:

Nausea, bouts of vomiting; Weakness and malaise, feeling thirsty; Headaches and pains in the region of the heart; Heart rhythm disturbances, changes in the ECG (shortening the period of contraction of the heart); Itching of the skin, dryness and signs of peeling; The joints are deformed, painful sensations appear in them when moving; The motility of the intestines and stomach is disturbed, this causes painful abdominal cramps and constipation. emotional lability; Signs of hypertension may appear;

If the tubules of the kidneys and their epithelial cells are affected, then pain occurs in the lumbar region, pyelonephritis or hydronephrosis may develop.

In case of blockage of the urinary tract, clinical signs of urolithiasis appear.

Due to pathological calcification of the tubules of the kidneys, their sensitivity to the influence of antidiuretic hormone decreases, as a result, the following symptoms appear:

Persistent decrease in the osmotic pressure of urine; Increase in daily diuresis; Polydipsia (resulting from intense thirst).

Diagnostics

Necessary laboratory and instrumental methods for diagnosing kidney nephrocalcinosis:

Nephrocalcinosis at the initial stages of its development has practically no clinical manifestations. In the early stages of the development of the disease, the most informative diagnostic method, but also the most invasive, is a kidney biopsy using a puncture technique. Ultrasound examination (ultrasound) is considered a fairly informative method for diagnosing kidney calcification in the early stages. On the obtained image, when scanning in various planes and sections, one can see a symptom of perimedullary rings of high echogenicity. Also, nephrocalcinosis of the kidneys on ultrasound is expressed by the following signs: (with a cortical form) linear hyperechoic neoplasms or a diffuse nature of the inclusion. Radiography and CT are effective already in the late stages of the development of calcification, when triangular-shaped pyramids or linear calcifications in the cortical layer of the kidney are clearly visualized in the picture. To determine the etiological and pathogenetic conditions for the development of the disease in children and adults, blood and urine are taken to determine the content of calcium and phosphorus in them. A general analysis of biological fluids (urine and blood), their biochemistry and the Sulkovichka test (calciuria level) are carried out. It is very important to assess the functional state of the kidneys, for this, creatinine clearance is determined, and the level of alkaline phosphatase is assessed. In order to determine the form of the disease (primary or secondary), the level of parathyroid hormone in the patient's blood is examined.

On the video, signs of early kidney nephrocalcinosis:

The attending physician, having fully studied all the results of the patient's research, prescribes medication, the purpose of which is to eliminate the root cause of the disease:

With severe dehydration of the body and violation of the acid-base balance, it is necessary to carry out intravenous drip infusion of solutions (sodium or potassium citrate, potassium aspartate, sodium bicarbonate or sodium chloride). If hypercalcemia is not significant, treatment with folk remedies is acceptable, which necessarily include a diet. Assign the intake of B vitamins orally or in injectable form. With the progression of renal failure or the development of a coma, hemodialysis is performed. A solution of magnesium sulfate or sodium phosphate is administered intravenously for hypercalcemia. Perhaps the appointment of hormonal drugs (prednisolone or thyrocalcitonin). When signs of pyelonephritis appear, treatment is appropriate for this disease.

Features of diet therapy

To reduce the level of calcium in the blood, it is very important to exclude the following foods: sunflower oil, mustard, sesame seeds, various types of cheeses. You can not eat wheat flour, bran, almonds, dairy products, oatmeal.

You should adhere to diet number 7, which causes the removal of toxins from the body.

Of the folk methods of treating kidney diseases, strawberries, strawberry leaves in the form of a decoction can be noted. The decoction is taken orally for about 10 days daily.

Gooseberries, viburnum and sea buckthorn have a good effect (anti-inflammatory and diuretic effect).

A decoction prepared for warm sitz baths of birch and sage leaves improves blood circulation in the vascular bed of the kidneys, relieves inflammation.

Prohibited foods for kidney nephrocalcinosis

With the progression of renal nephrocalcinosis, the prognosis for the future is unfavorable, since the development of renal failure and uremia is inevitable. With timely diagnosis of the disease and proper treatment, the prognosis for the development of the disease is more favorable. It is impossible to cure nephrocalcinosis with folk remedies, so it is very important to see a doctor in time.

The kidneys are a vulnerable organ that is susceptible to various infections, injuries and colds.

Therefore, it is necessary to constantly monitor their health and, if any problems arise, immediately engage in treatment.

The kidneys remove all excess substances from the body with urine, clearing it of unfavorable compounds, so the stability of their work is important.

Features of calcifications

With disturbed metabolic processes, calcium salts, calcifications, are deposited in the renal parenchyma.

These are the most common calculus-like formations, which are areas of dead kidney tissue covered with a dense precipitate of calcium salts.

They form in the zone of infiltration inflammation.

Often the development of calcifications is observed with concomitant diseases.

Kidney stones can be detected in adults and newborns (regardless of age and gender).

Causes

Salts are removed from the body along with urine. With impaired metabolic processes, unwanted components accumulate in the kidneys, turning into stones without proper treatment.

They can occur in the form of calcifications - deposits of calcium salts that are deposited on the walls of the kidneys, disrupting their function.

There are a large number of factors that can provoke kidney calcification. This manifests itself with dysfunction of the urinary system or its inflammation.

Often formations are detected in women during pregnancy, in the placenta. The cause of their appearance may be transferred intrauterine infections. Also, the presence of deposits may indicate impaired circulation of the placenta.

That is, stones signal adverse processes or poor-quality therapy for diseases.

With a massive accumulation of calcifications, one should undergo a qualitative diagnosis and consult a doctor for the appointment of therapeutic measures.

Diseases are provocateurs

Basically, calcifications develop with inflammation of the kidneys - glomerulonephritis. Also, a similar pathology can manifest itself after untreated or recently transferred kidney tuberculosis.

This kind of deposits are formed with tabulopathy, Graves' disease, cystinosis, vitamin D deficiency, renal failure, pyelonephritis.

Kidney calcification is typical for athletes who consume large amounts of protein.

For the treatment of kidney diseases, our readers successfully use Galina Savina's method.

At the same time, there are no symptoms of kidney damage, and the pathology can be detected as a result of a medical examination and ultrasound.

Varieties of deposits

The condition that characterizes the appearance of calcifications in the urine is called nephrocalcinosis, which is primary and secondary:

1. With impaired development and congenital diseases of the urinary organs, when the tubules are affected (tubulopathy), calcium precipitates in the papilla zone and the filtration processes worsen. Such a phenomenon is called primary nephrocalcinosis, it is characterized by calcium deposits in the proximal region of the nephron.
2. Secondary nephrocalcinosis is formed with sclerosis, ischemic necrosis of the renal tissues as a result of a tumor process or vascular pathology. Sometimes it manifests itself with mercury poisoning or an excess of drugs (ethacrine diuretics and amphotericin B). In this case, calcium accumulates in all parts of the nephron.

Features of the clinical picture

The disease can be asymptomatic (if calcification does not reduce the filtration capacity of the kidneys and there is no obstruction of the ureter).

In other situations, the symptoms of kidney calcification are:

• general malaise;
• violation of the digestive tract;
• constipation;
• pain in the joints;
• rapid fatigue;
• dizziness;
• decreased appetite and sleep.

These symptoms are associated with blockage of the urinary tract by stones.

Small urates and mucus may also be found in the urine. A large mass can block the lumen in the ureter, causing severe pain and blood in the urine.

With a large number of calcifications and with an increase in their size, the following symptoms appear:

• profuse and frequent urination;
• pain in the lumbar region;
• more yellow skin tone;
• swelling of the limbs;
• an unpleasant odor from the oral cavity (with the accumulation of urinary toxins in the blood);
• dehydration of the body, strong and unquenchable thirst;
• increase in blood pressure;
• an increase in the amount of protein in the urine.

Diagnostic methods

The doctor can determine the deposition of certain deposits in the kidneys using an X-ray examination.

Due to the fact that the consistency of the stone is similar to bone, a dense stone-like formation is clearly visible on the x-ray.

A more detailed study can be carried out using magnetic resonance or computed tomography. In this case, the exact parameters and location of the calcification are determined.

In the early stages, a needle biopsy is considered an effective research method, since pathological changes cannot be seen with the help of X-rays and ultrasound.

Ultrasound of the kidneys is required for the most part to detect concomitant kidney diseases.

The doctor also prescribes blood and urine tests for the concentration of this component. Parathyroid hormone and vitamin D levels are required.

A biochemical study of blood and urine is carried out, which reveals the presence of phosphorus and calcium, acid-base balance, alkaline phosphatase activity and excretion of hydroxyproline with urine.

On MRI, calcifications in the parenchyma of the right kidney

What can and should be done?

The main goal of treatment is to eliminate the factors that provoke kidney calcification.

To normalize the volume of calcium, the following methods are used:

• citrate and sodium bicarbonate are introduced;
• with alkalosis, sodium chloride (ammonium) is prescribed (to change the balance to an alkaline environment), with acidosis, potassium aspartate (citrate) is introduced (to change the balance to an acidic environment);
• B vitamins;
• nutrition with a limited intake of calcium ions in the body.

Nutrition Features

Diet with calcifications in the kidneys is of paramount importance.

To reduce the intake of calcium in the body, the consumption of sunflower seeds, mustard, sesame seeds is limited.

Also, do not eat:

• hard and processed cheeses;
• halva;
• cheese;
• almond;
• condensed milk;
• yeast;
• wheat flour and bran;
• walnuts and nutmegs;
• dill;
• parsley;
• legumes;
• milk;
• garlic;
• oatmeal;
• sour cream;
• cottage cheese;
• black bread and cabbage.

The main nutrition corresponds to the treatment table No. 7 (to reduce extractive components and accelerate the removal of toxins).

Salt is excluded, cilantro, cinnamon, citric acid, cumin are added to the diet.

Also, the following measures are used to remove salts:

• the use of diuretics and herbs (but the volume of fluid does not increase);
• the use of anti-inflammatory drugs, since excreted salts cause pain, irritating the mucous membrane.

Preventive measures

There are no basic principles for the prevention of calcification, since there are so many reasons for the appearance of a pathological process.

But doctors advise to carry out timely and comprehensive treatment of inflammatory and infectious diseases.

It is necessary to monitor nutrition, consuming quality products and controlling the composition of drinking water. You also need to lead an active lifestyle.

The recovery time depends on the stage of the pathological process.

Basically, at the initial stages, therapy becomes effective, but with the development of renal failure and progression, severe complications can develop with the appearance of uremia, which without surgery can lead to death.

In contact with

Calcifications in the kidneys or nephrocalcinosis is a rather dangerous disease in which calcium salts are deposited in the kidney parenchyma. This organ performs an important function in the human body, filtering all harmful substances, bringing them out with urine.

The work of the kidneys can be disrupted for many reasons, even the common cold often negatively affects the activity of this system. Renal pathologies upset the function of the whole organism, so their consequences can be severe. Treatment of this disease should be carried out under the supervision of a nephrologist, often in a hospital setting.

Features of the disease

Kidney nephrocalcinosis usually occurs due to a metabolic disorder in the body. The deposition of calcium salts is accompanied by additional disorders in this area, inflammation of the kidneys and sclerotic changes in this organ. Such pathologies are dangerous because they are more likely to develop chronic renal failure.

Mechanism of Education

Calcifications in the kidneys, settling on the tissues of the organ, form a stone sediment. Under a layer of settled salts, a part of the kidney dies. The problem area is covered with replacement tissue, which does not allow the organ to function normally, this area is no longer involved in urine filtration. There are no specific age restrictions for this pathology; both adults and children can get sick. Treatment must begin at an early stage of the disease, while these stones are rare.

Calcium is found in bone tissue, it is released into the blood when needed. Saturation with vitamin D, which also takes part in the synthesis of calcium salts, is possible through food or with the self-production of this element by the body. Exposure to sunlight on the skin promotes the synthesis of vitamin D.

The thyroid gland produces the hormone calcitonin, which can reduce the concentration of calcium salts in the blood, as well as affect the excretion of this substance in the urine. If the activity of the thyroid gland is upset, the synthesis of calcitonin is also impaired.

In addition, the parathyroid glands secrete the hormone parahormone, which determines the concentration of calcium salts in human blood. The more this element is synthesized, the less parahormone is produced.

It is this type of hormone that directly affects the content of calcite in the body, so if certain conditions are created, then the parahormone will cause nephrocalcinosis of the right or left kidney. Often, treatment is needed to restore thyroid function in order to stop the production of calcifications in the kidneys.

Causes

Physicians distinguish primary and secondary causes of the formation of calcifications. In the case of the primary variety of the disease, the formation of calcium salts is influenced by disorders in the kidneys and urinary tract of a congenital nature, and the secondary ones occur as a result of other pathologies of this organ.

Causes of secondary nephrocalcinosis:

Calcium salt stones can form for many more reasons; only a doctor can determine the exact factors that affect this pathology. Calcifications in the kidneys often appear due to undertreated pyelonephritis. With improper therapy, this disease becomes chronic and does not manifest itself clearly, a person may not be aware of the sluggish inflammatory process of his body, and during this period salts accumulate in the kidney.

A particular problem is that it is very difficult to diagnose this disease at an early stage, when single calcifications appear in the kidneys and there are no symptoms. Usually, this pathology is detected during a routine examination using ultrasound diagnostics performed on this area of ​​the body to identify another ailment.

How does the disease manifest itself?

It is almost impossible to notice nephrocalcinosis at the initial stage of the formation of calcium salt deposits. The peculiarity of the structure of the kidneys has such a problem. The kidneys are a paired organ, so if a violation occurs in one side of it, the second will completely take over all the functions.

The acute course of this disease may have characteristic signs by which the doctor may suspect nephrocalcinosis.

Signs of the disease:

Intense pain in the kidney area can appear only when the lumen of the ureter is blocked by a large calculus, and often there is an admixture of blood in the urine, which is due to constant irritation of the mucous membrane with grains of salt.

In addition, such patients often complain of an increase in blood pressure, if the disease has already developed enough, then blood pressure is constantly elevated. Nephrocalcinosis in children develops, as a rule, very quickly. If a child has swelling or other signs of this pathology, immediate hospitalization is necessary for a thorough examination and treatment.

The peculiarity of the course of this disease in a child is that the body of babies is not able to fight the disease for a long time, as is observed in adults. It should be noted that the tactics of treating this disease are the same in children and adults, the differences are in the treatment of concomitant diseases that caused nephrocalcinosis.

We must not forget that multiple calculi in the kidneys can mean a tumor process of a malignant nature in this area of ​​the body, and single calcifications do not give rise to suspicions of oncology.

There are several varieties of such formations, on which the treatment and course of the pathology depends.

1. Cortical nephrocalcinosis appears as a result of the development of acute necrotic disorders.
2. Medullary nephrocalcinosis is a continuation of the cortical one.
3. Independent nephrocalcinosis appears against the background of metabolic disorders in the human body.

Deterioration of sleep and loss of appetite, as well as general ailments accompany the patient for a long time. The more neglected the process of pathology, the stronger the manifestations of the disease, especially in children.

Diagnostics and therapy

The first method of examination of such patients is x-ray. Due to the similarity of calcifications with bone tissue, an x-ray will perfectly reveal the presence of these formations in the kidneys. For a more accurate examination of patients, MRI and CT diagnostics are used, as well as laboratory methods for examining urine and blood.

Ultrasound diagnostics is also able to detect the presence of salt stones in the kidneys, but there is a possibility that the doctor may confuse nephrocalcinosis with another ailment that is similar to kidney calcifications.

A tissue biopsy is carried out at the initial stage of the development of this pathology, since the histological examination will determine the extent of the disease and prescribe the correct therapy.

Drug treatment of this disease is to eliminate the cause that caused the disease. There is no special therapy for this disease, the doctor makes a decision on prescribing drugs, assessing the specific situation of each patient. Surgery to eliminate formations from the kidneys is usually ineffective, therefore, it is used in rare cases. This disease is not considered deadly, but its complications can be very severe.

Therapy is usually based on the removal of inflammatory processes in the kidneys and urinary tract, the prevention of calcification in the problem area, and the appointment of a therapeutic diet. Severe cases of this disease require the appointment of drugs that eliminate pain, as well as improve kidney function.

For this purpose, the following drugs are used:

• anti-inflammatory (Voltaren, Rifampicin);
• antispasmodic (No-shpa, Papaverine);
• improving renal blood flow (Kurantil).

Diet is considered a very important element of therapy, so you need to strictly limit the consumption of prohibited foods. The following foods should not be consumed:

The basis of all meals for people with nephrocalcinosis is diet number 7, which helps to remove all harmful substances from the body.

It is necessary to treat the formation of calcifications in the kidneys in a timely manner so that the complications of the pathology do not have time to appear, then the prognosis of the disease will be favorable, and the person will be able to live fully. For children, it is especially important to identify this disease in time and start treating it; the consequences of this pathology in babies can develop much faster than in adults.
