Features of nephrosclerosis and methods of treating a shrunken kidney

Different types of pathology

Kidney diseases, including nephrosclerosis, can occur in both men and women. According to statistics, they are more often diagnosed in children under seven years of age, in women during the reproductive period, elderly men, and people suffering from alcoholism.

Such changes lead to the fact that the size of the kidney changes, it becomes smaller. After its functions are significantly impaired, the tissues die, surgical intervention is required - the organ is removed.

There are two types of pathology:

• primary shrinkage of the kidney;
• secondary shrinkage of the kidney.

Primary wrinkled kidney is a rare pathology that leads to the development of chronic organ failure. The disease occurs against the background of vascular damage to the kidneys, which is a consequence of arterial hypertension.

Secondary wrinkled kidney - the formation of such a pathology is associated with the presence of an inflammatory or infectious process in the body. This is a more common form of nephrosclerosis, which occurs due to damage to kidney tissue, glomeruli (glomeruli) and other diseases.

A child may develop a wrinkled kidney due to secondary reflux that develops against the background of abnormal development of the kidneys (renal multicystic disease, Eagle-Barrett syndrome, meningomyelocele, etc.).

Secondary wrinkling can cause chronic renal failure or arterial hypertension in a malignant form.

With the active development of pathological processes, the chances of complete relief from the disease are very low.

Distinctive features of the primary and secondary forms of the disease

Primary and secondary wrinkled buds have minor differences. They lie in the factor that provoked the development of the pathology - a concomitant disease.

In patients who have been diagnosed with damage to their own arterial tissues, a primary shriveled kidney develops. The main precursors of this form of pathology are: high blood pressure, in which hypertensive crises are observed, and milder diseases of the cardiac and vascular system.

If a patient has pathologies of the excretory system, his parenchyma begins to thin out and lose its functional ability, and accordingly, a pathology develops - a secondary shriveled kidney.

When studying the features of the pathology, you should know the reasons under the influence of which a disease such as secondary wrinkled kidney develops:

• infectious damage to an organ by tuberculosis bacteria;
• bacterial damage to the kidney tubules of a nonspecific nature;
• damage to the glomeruli;
• formation of stones in the organ cavity;
• diabetes.

All of these diseases lead to circulatory problems. Lack of blood leads to unilateral or bilateral shrinkage of the organ. The process can last for years, and in weakened areas, connective tissue first grows, and then a scar forms.

Considering that a secondarily wrinkled kidney has various causes for its formation, and that renal failure develops against its background, this diagnosis is quite common in urology. Each patient needs regular medical examination and an extrarenal blood purification procedure, which allows toxic substances to be removed from the organ.

Why does nephrosclerosis develop?

The causes of drying out of the renal parenchyma directly depend on the form in which the disease occurs.

Primary changes are associated with the following pathologies:

• Atherosclerosis, which is accompanied by the appearance of seals in the vessels and a decrease in the elasticity of the arterial walls. The lumens of blood vessels narrow and sclerotic plaques form, which include fats, calcium and cholesterol.
• Arterial hypertension in a chronic form, which is accompanied by high blood pressure.
• Kidney infarction – as a result of this disease, atrophy of the kidney tissue occurs. Pathology develops due to blood flow disturbances.

Secondary desiccation is associated with various diseases that negatively affect kidney activity:

• diseases accompanied by kidney inflammation (glomerulonephritis, pyelonephritis);
• kidney tuberculosis caused by pathogenic microbacteria;
• nephrolithiasis - a disease in which stones form in the kidneys;
• diabetes mellitus accompanied by insulin deficiency;
• systemic lupus erythematosus is an autoimmune disease in which the immune system begins to attack the body’s cells, perceiving them as “strangers”;
• kidney amyloidosis - a disease caused by a disorder of protein metabolism;
• injuries and surgery on the kidneys - particles of kidney tissue can lead to blockage of arteries and renal arterioles. Impaired blood circulation leads to nephron death.

In addition, kidney shrinkage can be benign, in which the pathological processes proceed slowly, and malignant, in which the course of the disease progresses more quickly.

Disease prevention

Among the many preventive measures to prevent kidney shrinkage, the following should be highlighted:

• timely treatment of infectious pathologies (pyelonephritis, kidney tuberculosis, etc.);
• adequate measures for the treatment of glomerulonephritis;
• adherence to renal diet No. 7;
• timely correction of metabolic disorders and pathologies (metabolic syndrome, diabetes, obesity, etc.);
• prevention of colds of the genitourinary system;
• maintaining an active lifestyle;
• absence of bad habits (smoking causes a slowdown in blood flow, and alcohol, on the contrary, accelerates it excessively);
• prevention of kidney injuries;
• drinking purified water;
• periodic examination by a urologist or nephrologist.

The prognosis for a shriveled kidney is unfavorable, since in any case the pathological cascade will lead to its complete inability to perform its filtration function. But with proper treatment, the progression of the process can be significantly slowed down. Renal shrinkage is the main indication for transplantation or hemodialysis.



A wrinkled kidney is one of the symptoms of nephrosclerosis. The kidneys become deformed (shrink) as a result of the active growth of connective tissue in them, due to which they become significantly denser and change their shape and structure. This disorder has another name - nephrosclerosis.

This pathology occurs quite often in long-term renal diseases and in most cases leads to the patient developing a chronic version of renal failure. Therefore, patients with this diagnosis often require constant hemodialysis or a donor kidney transplant.

The disease can have 2 forms:

• nephrosclerosis resulting from impaired renal circulation;
• nephrosclerosis, which appears due to the inflammatory process or dystrophic transformation of the stroma, glomeruli and tubules of the organ.

How does the disease manifest?

Nephrosclerosis is accompanied by various kinds of symptoms that affect the body as a whole.

Table 1: Main signs of nephrosclerosis

In addition to the above, the patient experiences swelling.

Another symptom of a shriveled kidney is increased blood pressure. In this way, the body’s compensatory mechanisms are activated, temporarily improving blood flow to the kidneys. Also signs of the disease are decreased immunity and a tendency to bleed.

With the development of nephrosclerosis, the death of nephrons occurs gradually, affecting individual areas of the organ. Therefore, there are several stages of the disease, each of which is accompanied by certain processes.

What to do if your kidney hurts?

Have you been trying to cure your KIDNEYS for many years?

Head of the Institute of Nephrology: “You will be amazed at how easy it is to heal your kidneys just by taking it every day...

The kidneys hurt when their functions are impaired and various diseases occur. The symptoms are different. Unpleasant sensations in the lower back also occur with diseases of other organs. This article will tell you in detail how to understand that the problem is with the kidneys and what to do about it.

Where do the kidneys hurt?

These organs are located on both sides of the spine, at the level of the lower ribs. Outwardly, they look like bean grains weighing about 150 g. Under the outer shell there is a complex blood filtration system. As the blood passes through the kidney tissue, it is cleared of toxic metabolic waste. Necessary substances - minerals, proteins, vitamins - are returned to the blood. Waste is collected in the renal pelvis, sent through the ureter to the bladder and expelled during urination. Painful sensations occur on one or both sides, it depends on whether one kidney or both are affected by the disease.

Kidney pain is similar to signs of osteochondrosis, radiculopathy or intervertebral hernia, but spinal diseases have characteristic differences:

1. Aching or shooting pain radiates to the leg, intensifies with movement. It prevents a person from straightening up and forces him to maintain a tense posture.
2. The horizontal position of the body alleviates the patient's condition.
3. The temperature is not elevated, there is no chills, no sweating.
4. Urination is painless, there is no turbidity, blood or pus in the urine.

Such symptoms indicate that the cause of the pain is associated with the spine.

Important! When a back muscle is bruised or sprained, pain in the kidneys is often attributed to injury. But internal organs can also be damaged - bruised, ruptured or crushed. This is a dangerous situation in which it is impossible to do without medical help. If after a back injury the appearance of urine has changed, blood has appeared, or your body temperature has risen, you should consult a doctor.

Other diseases also cause discomfort in the lower back:

1. Gallstones.
2. Inflammation of the pancreas.
3. Gynecological diseases.
4. Stomach or duodenal ulcer.
5. Aortic aneurysm.
6. Acute appendicitis.

How can you tell if your kidney is hurting?

A characteristic symptom indicating kidney disease is a change in urine. The color, smell, transparency changes, and impurities of pus or blood appear. The amount of urine excreted decreases. Other symptoms may also appear:

1. Stinging, shooting or pulsating on one side of the spine.
2. Drawing or aching pain, a feeling of heaviness in the lower back.
3. Urination is frequent, painful, intermittent.
4. A person is thirsty and has a dry mouth.
5. Swelling - constant or morning - appears on the face, arms and legs.
6. General deterioration of health - intoxication causes weakness, dizziness, loss of appetite.
7. Body temperature rises, chills, nausea, and vomiting begin.
8. Blood pressure rises.

If there is pain in the kidneys and the presence of accompanying symptoms, treatment and observation by a nephrologist is required.

Why do my kidneys hurt?

The kidneys can hurt because a person has drunk a lot of liquid, and they work hard to remove it from the body. Alcoholic drinks load the kidney tissue with additional work - neutralizing toxic metabolites. During intense physical activity - fast running, training in the gym - discomfort arises from the fact that a large volume of blood is pumped through the kidneys.

Often, kidney pain is caused by more serious causes:

1. Inflammatory processes - glomerulonephritis, pyelonephritis.
2. Infections - urological or venereal.
3. Nephroptosis (organ prolapse).
4. Complications after sore throat, flu.
5. Urolithiasis disease.
6. Cysts - single, multiple (polycystic).
7. Neoplasms - benign or malignant.
8. Stenosis (narrowing) of the renal artery.
9. Blockage of an artery by a thrombus, atherosclerotic plaque.
10. Injuries - bruise, rupture, wound.

Diseases that cause kidney pain occur at any age. A nephrologist must determine their cause.

In children, congenital pathologies occur, inflammatory processes occur from hypothermia, and in case of disturbances in water-salt metabolism, sand and stones occur. A child’s complaints of lower back pain are a serious reason to contact a pediatrician.

During pregnancy, discomfort in the lumbar region appears from an enlarged uterus, which puts pressure on the organs surrounding it. Painful manifestations intensify with exacerbation of chronic diseases and the development of renal failure. This condition is dangerous for women and children. The expectant mother must be hospitalized for treatment under the supervision of specialists.

How do your kidneys hurt?

The nature of the pain syndrome depends on the disease that causes it. Based on the description of symptoms and examination results, the nephrologist makes a preliminary diagnosis and prescribes tests to clarify it. It is necessary to tell the specialist in detail where and how the kidney hurts.

Renal colic

Piercing, unbearable pain in the kidney area is a symptom of renal colic. It radiates to the groin, perineum, abdominal cavity, rectum. Urine excretion decreases, blood and cloudy sediment appear in it. The patient turns pale and breaks out in a cold sweat. An attack begins when the outlet of the ureter from the renal pelvis is blocked. Urine is not excreted, causing severe pain in the kidney. Often the urine output is blocked by stones, but blockage by a clot of pus or a neoplasm is possible.

Only a nephrologist can determine the cause of the attack. All that can be done at home is to provide the patient with peace and call an ambulance. You should not try to stop the attack on your own. When the stone or clot comes out, the pain in the kidney stops. But if this does not happen, complications will arise that cannot be dealt with without the help of a specialist. A late visit to the doctor reduces the patient’s chances of a successful outcome.

Colic attacks are dangerous for pregnant women and children. Pregnant women with acute colic are often hospitalized in the maternity ward, as the symptoms are similar to premature birth. It is difficult to diagnose renal colic in young children who are unable to explain what is bothering them. They require hospitalization for an accurate diagnosis and treatment.

Note! Often, renal colic begins when the patient attempts to independently remove stones due to kidney stones. Eating large amounts of cucumbers, watermelon or diuretic herbal preparations leads to the movement of stones and blockage of the ureters, provoking an attack.

Throbbing pain

Painful throbbing on one side of the lower back may be a sign of kidney failure. This is a pathological condition in which the kidney tissue cannot cope with the purification of the blood, so the body begins to suffer from intoxication. In addition to pain, dizziness and shortness of breath appear, blood pressure rises, and heart function is disrupted. Severe kidney failure can lead to death, so throbbing pain in the kidneys cannot be ignored.

Aching, pressing or pulling pain

Kidneys ache during inflammatory or infectious processes. Kidney pain is accompanied by urological signs of inflammation: the amount of urine decreases, it becomes foul-smelling, dark or colorless. Pain when urinating indicates irritation of the urinary tract. Swelling, dry mouth, and thirst appear. Weakness, loss of appetite, nausea, and vomiting often accompany aching pain in the kidneys. Rising temperature, chills and fever mean that the disease is progressing. If the disease is not cured, it will become chronic, then the kidneys will hurt with every exacerbation.

The back constantly aches due to kidney stones. Stones and sand irritate surrounding tissues, causing inflammation. If the stones move, getting stuck at the entrance to the ureter, acute pain occurs - renal colic.

If the lower back aches periodically, when lifting weights or being in a vertical position, this may be a symptom of nephroptosis. The organs are held in place by tendons and fat. If this layer becomes thinner and the ligaments become weaker, the kidney may move down or to the side. Tension of the ligaments causes pain. Prolapse most often occurs in women after pregnancy, childbirth, or with significant weight loss. This pathological condition is dangerous because when displaced, the kidney can turn, twisting the blood vessels. The access to blood will be blocked, which will lead to necrosis - tissue death.

Pressing pain in the kidney is a symptom of a cyst or tumor. It appears when the tumor grows so large that it begins to put pressure on the nerve endings. Pressing pain from neoplasms is accompanied by weight loss, loss of appetite, weakness, and sweating. With such symptoms, it is unacceptable to waste time on self-medication. Oncological diseases develop unnoticed, pain syndrome appears at a late stage of the disease, when it is difficult to cure.

What should you do if your kidneys hurt?

Contact your doctor. Kidney diseases are life-threatening and should not be treated on your own. If you have aching, throbbing, pressing pain, you should visit a therapist and get tested. Based on their results, the doctor will refer the patient to a specialist: a urologist, nephrologist or oncologist for detailed examination and treatment.

If the pain is sharp, cutting, you should immediately call an ambulance. If the pain is tolerable, you can use the following recommendations:

1. Drink No-shpa, Papaverine or another antispasmodic drug.
2. Maintain bed rest.
3. Stick to a diet.
4. Drink clean water, compote or fruit juice - these drinks are healthier for the kidneys than tea or coffee.

Therapeutic diet

A distinctive feature of this diet is the reduction in the amount of protein foods. It is recommended to eat vegetables, fruits, cereals, and dairy products. Lean meat, lean fish and poultry are included in the menu 1-2 times a week. The amount of salt is reduced to a minimum. Eating boiled, stewed, steamed dishes from permitted foods reduces the load on the urinary system. Vegetable soups, porridges, salads with vegetable oil, stewed vegetables, fresh fruits - a varied, healthy diet for a sick person. Watermelons and cucumbers, which have a diuretic effect, are recommended to be consumed in small quantities. Herbal teas are allowed with the permission of the attending physician.

If your kidneys hurt, you need to be treated by a nephrologist or urologist. To prescribe adequate treatment, it is necessary to conduct a detailed examination and make an accurate diagnosis. Self-medication for kidney diseases leads to severe complications, and in some cases, death. Treatment under the supervision of a competent specialist will eliminate the cause of painful manifestations and restore health.

Diagnosis of the disease

To identify pathological changes, a comprehensive diagnostic study is prescribed. The doctor collects medical history data:

• complaints and data on the manifestation of the disease - when the first signs of the disease appeared, whether the patient sought medical help, etc.;
• clarifies the presence of chronic diseases;
• finds out whether the patient’s close relatives have been diagnosed with a shriveled kidney and other kidney diseases, oncology.

The specialist examines the patient with obligatory palpation of the kidney area.

To detect the process of kidney drying, a number of laboratory tests are prescribed:

• general analysis of urine and blood;
• taking a biochemical blood test.

In nephrosclerosis, important indicators are the shape and size of the affected organ. To find out, the following research methods are used:

• Ultrasound (ultrasound examination);
• X-ray of the peritoneum is one of the most informative research methods at the early stage of the disease, allowing one to assess the condition of the glomerulus and urinary tubules.
• Angiography is a contrast X-ray examination of the blood vessels, which allows one to assess the condition and number of renal arteries and their structure.
• MRI - Magnetic resonance imaging is prescribed to obtain an accurate three-dimensional image of the affected organ.
• Contrast computed tomography – the result is a layer-by-layer image of the kidney.

In most cases, it is recommended to consult a urologist.

The diagnosis of nephrosclerosis is made on the basis of complex data obtained.

How is kidney shrinkage diagnosed?

First of all, the doctor analyzes the patient’s medical history:

1. An analysis of the patient's complaint history is carried out to establish the time of the first development of symptoms, the nature of the symptoms, and the nature of their development over time. The presence of previous visits to a doctor and treatment, the type of examination performed and its results are also established.
2. An analysis of the life history is carried out to clarify the presence of chronic kidney pathologies, to clarify the patient’s bad habits, the presence of diseases of the genitourinary system, and to identify the patient’s working conditions and living conditions.
3. An analysis of family history is carried out to determine the presence of kidney damage and cancer pathologies in the patient’s closest relatives.

Next, the patient is examined by a doctor and palpated the kidney area, which makes it possible to identify the presence of pain, changes in the skin, such as redness or rashes in the kidney area.

Laboratory methods for diagnosing renal shrinkage include the following: a complete blood count, a complete urinalysis and a biochemical blood test.

Methods for diagnosing the location, size and shape of the kidneys include:

• Ultrasound examination of the kidneys, that is, examination of tissues and organs using ultrasonic waves - high-frequency sound vibrations.
• Abdominal radiography is a diagnostic method that allows one to obtain a picture of internal organs due to the property of X-ray radiation to penetrate the human body and be absorbed by tissues in different quantities.
• Angiography is a diagnostic method that involves organizing an X-ray examination of blood vessels with additional preliminary administration of a contrast agent into the body. This method makes it possible to determine the number and condition of the kidney arteries, as well as the vascular structure of the kidney. When the kidney dries out, a characteristic sign is revealed - this is kink and narrowing of the lumen of the kidney artery and its branches, as well as the absence of a pattern of small branches.
• MRI or magnetic resonance imaging is a diagnostic method in which a specialist takes special images. This method is based on the use of the physical properties of nuclear magnetic resonance. The examination is completely safe for the human body.
• Computed tomography using a contrast agent is a type of x-ray diagnostics using contrast, which helps to obtain a complete picture of the necessary organs on a computer.

Treatment of the disease

Therapy is prescribed based on what stage of development the organ shrinkage is at.

If the pathology can be identified at an early stage, when it does not have severe symptoms, drug treatment is used. This may include taking the following medications:

• anticoagulants (“Heparin”, “Antithrombin III”, etc.) - anticoagulants;
• potassium preparations (“Asparkam”) – normalizing salt balance;
• antiplatelet agents (“Acecardol”, “Trentaloma”) – improving blood flow;
• multivitamin complexes;
• vitamin D;
• iron preparations (“Hemofera”, “Ferroplexa”, etc.) - eliminating the anemic condition;
• sorbents (“Polysorb”, “Enterosgel”, etc.) – absorbing and removing toxic components from the body);
• calcium antagonists (“Verapimil”, “Anipamil”) - drugs that eliminate arterial hypertension;
• diuretics (Furosemide) - used for high blood pressure.

Such therapy will stop the progression of the disease and improve the condition and functionality of the affected organ. But what to do if the disease is detected at later stages of development? In this case, the patient is recommended to undergo regular hemodialysis or surgery.

If chronic hemodialysis is indicated, the patient requires a kidney transplant.

Modern medicine offers several options for performing the operation:

• abdominal surgery is a traditional method in which an incision is made in the peritoneal cavity;
• laparoscopic surgery - insertion of tubes connected to equipment into the peritoneum through microscopic holes.
• performing percutaneous endoscopic retroperitoneal nephrectomy - removal of the organ through a puncture in the lumbar region.

Any surgical intervention requires further recovery, but with minimally invasive procedures this process goes faster.

Diet food

For nephrosclerosis, a diet is necessarily recommended, the main goal of which is to reduce the load on the affected kidney.

To unload the organ, you should adhere to the following rules:

• Reduce salt and protein intake.
• Eat lean meat and fish.
• Eliminate foods that contain potassium from your diet.
• It is recommended to stick to fractional meals.
• Eat more foods rich in magnesium.
• Stick to a fluid intake regimen (as prescribed by your doctor individually).

With a wrinkled kidney, it is important to follow all recommendations, since any violation can significantly worsen the patient’s condition.

As for the outcome of the disease, everything depends on the available factors. With benign nephrosclerosis, the patient has a chance to return to his usual lifestyle, however, some correction will be required. With malignant lesions, the prognosis is not so favorable - most often regular hemodialysis followed by transplantation is required.

Kidneys are one of the most hardworking organs, capable of functioning fully, even if the right or left part is lost. However, it requires careful treatment and adherence to the regime - after all, avoiding an illness is much easier than treating it.

What are the forms of nephrosclerosis?

Depending on the operating factors, there are 2 forms of nephrosclerotic lesions:

Both options have an unfavorable prognosis and can cause death. In each specific case, it is necessary to identify the cause and begin treatment as early as possible in order to prevent the development of irreversible renal failure.

Primary wrinkling

Hypertension or atherosclerosis in the vessels causes disruption of arterial-venous blood flow: without receiving the necessary nutrition, renal parenchyma cells quickly die and their size rapidly decreases. Primary nephrosclerosis is caused by external vascular factors - high blood pressure or plaque thrombosis of the artery kills the organ, sharply increasing the risk of developing primary renal failure.

How to stop nephrosclerosis using folk remedies

Patients very often experience sleep disturbances, weakness, general condition worsens, and they quickly get tired. If the main cause of nephrosclerosis is diabetes mellitus, atherosclerosis or hypertension, then the process of reducing the kidney in size can take several years. In such situations, the patient may not even be aware of the violations and complain only about the deterioration of his general condition.

With amyloidosis or glomerulonephritis, organ damage occurs much faster, in about two years. If the cause is glomerulonephritis, then both kidneys are immediately affected. For diabetes mellitus - one. However, the process progresses quite quickly.

If creatinine and urea continue to rise even while taking medications, then it is necessary to follow a diet that will reduce the load on the kidneys.

Healthy nutrition and diet

First of all, you should limit the amount of protein and table salt you consume. It is better to replace fatty meat with lean poultry and fish. You can also diversify your diet with cereals, pasta and potato dishes.

You need to exclude from your diet fruits that contain a lot of potassium, for example, grapes, bananas, apricots, as well as cottage cheese and cheese, dried fruits such as dried apricots, dates and prunes.

You need to eat small and often. The diet should include foods rich in magnesium, for example, pine nuts and walnuts, buckwheat, and seaweed. It is also worth preparing to consume homemade infusions of medicinal herbs that increase blood flow, and mineral waters with magnesium, for example, Borjomi and Essentuki No. 4.

Lingonberry leaves, honey and lemon are a real salvation

Taking traditional medicine for nephrosclerosis does not completely cure the disease, but it will help stop its development. The most effective remedy for cleansing the kidneys is a decoction of lingonberry leaves. To prepare it, take 50 grams of lingonberry leaves and fill them with 400 grams of water.

Put everything on fire. Let the decoction boil and boil for another 15 minutes. Strain the finished decoction of lingonberry leaves and cool. Use the product 4 times a day, 100 milliliters before meals.

Honey has long been considered a panacea for all ailments. For the treatment of nephrosclerosis, the following medicine can be prepared. Take 200 grams of honey and lemon. Mix everything and heat in a water bath. Take this remedy once a day, a tablespoon 30 minutes before meals. Store the remaining mixture in the refrigerator.

Cleansing the body

Also, with nephrosclerosis, it is worthwhile to improve the digestive system. However, toxins should be released not through the kidneys, but through the intestines.

In any case, porridge is good for the body. In addition, this product perfectly cleanses the body of toxins and waste. To prepare healing porridge you will need oats and rice. Take them in equal parts, wash them thoroughly and then boil them. Cook the porridge until it becomes thick.

Eat this porridge without oil and almost no salt. For a glass of washed cereals, take two and a half glasses of water. It is worth noting that such porridge not only removes harmful substances from the body, but also promotes the healing of accidentally damaged walls of the digestive system.

Beetroot removes waste and toxins

Another excellent remedy that allows you to cleanse the body of toxins is beets. To prepare, you will need one boiled beet and three tablespoons of beet pulp. Grate the beets and squeeze out the juice. Let it sit for two hours and take it at night. Roll beet pulp into balls and take them 30 minutes before meals. The balls should simply be swallowed without chewing.

If you experience general malaise and other signs of a wrinkled kidney, do not self-medicate. Contact a specialist immediately. Only a doctor can prescribe the correct treatment after an examination.

Causes of kidney pathology

To establish the cause of the disease, it is first necessary to correctly diagnose the form of the disease. Thus, a primary wrinkled kidney occurs as a result of damage to its blood vessels. Diseases that can disrupt the integrity of the vascular system of an organ:

1. Atherosclerosis. Reduced elasticity of artery walls and, as a result, their hardening. The blood vessels narrow, which leads to the formation of calcium, fat and cholesterol plaques.
2. High blood pressure (hypertension).
3. Kidney infarction. Due to impaired blood flow in the organ, tissue atrophy occurs.

The secondary form of kidney shrinkage is the result of other diseases of the organ if they are not treated. These include:

1. Kidney tuberculosis. It is caused by microbacteria tuberculosis.
2. Nephrolithiasis. Formation of stones in the organ cavity.
3. Glomerulonephritis and pyelonephritis. They arise as a result of inflammatory processes.
4. Diabetes. Shrinking occurs due to lack of insulin.

Diagnosis of the disease

Regardless of the causes and form of the disease, there are symptoms that clearly indicate nephrosclerosis. One of these is poor urine outflow or a high daily rate of urine excretion, the main percentage of which occurs at night. Other symptoms include:

• detection of protein in urine with low specific gravity;
• increased blood pressure;
• lower back pain.

To make an accurate diagnosis, identify the causes of alarming symptoms and determine the form of the disease, as well as the degree of organ damage, a set of diagnostic measures is prescribed.

A survey and visual inspection is carried out. The doctor collects information about the presence of other diseases, lifestyle, whether there were previously problems with the urinary system and what treatment methods were used. The kidneys are palpated and the skin is visually examined to identify a rash or other manifestations of the disease. If nephrosclerosis is suspected, the doctor prescribes tests to determine the clinical picture of the disease. The patient is prescribed:

• general blood and urine analysis;
• biochemical blood test;
• Ultrasound;
• radiography;
• MRI;
• computer diagnostics with the introduction of a contrast agent into the body.

Treatment of nephrosclerosis

According to the tests, treatment is prescribed strictly on an individual basis.

If changes in the kidney do not affect the general health, except for increasing blood pressure, the patient is prescribed a salt-free diet. Medications that increase metabolic processes and antioxidants are prescribed. If the disease is accompanied by renal failure, then the above drugs are unacceptable, as they lower blood pressure, which will lead to disruption of the blood supply to the organ. A diet that excludes meat products is prescribed to normalize the level of nitrogen toxins.

If the disease affects only one kidney, then the second can compensate for its loss of functionality.

When both kidneys are affected, arterial embolization and lifelong hemodialysis are prescribed. An alternative is a donor organ transplant.

Clinical picture and mechanism of formation

At the first examination, doctors cannot make a final diagnosis. However, there are a number of symptomatic manifestations that are characteristic exclusively of nephrosclerosis. The most striking is the dysfunction of urine excretion, which the patient indicates when collecting anamnesis. Analysis of biological material shows that the daily norm has been exceeded. At the same time, more urine is excreted at night than during the day.

Less obvious manifestations include:

1. Presence of protein in urine.
2. The specific gravity of urine is below normal.
3. Blood pressure is consistently elevated.
4. There have been cases of hypertensive crisis.
5. There is pain in the lumbar region.

A secondary wrinkled kidney is a macropreparation, the characteristic feature of which is partial preservation of its shape, while simultaneously reducing weight and size. As the pathology progresses, the color of the organ changes. In the initial stage, the kidney has a clear shade of blood, and with its deficiency, the organ acquires a gray tint, and visible scars appear on the surface. No sites of hemorrhage are detected.

The probable cause of the clinical indicators can primarily be considered the deposition and blockage of the renal vessels by cholesterol plaques, which led to the development of hypertension. Secondary causes are often pathologies of the stroma, tubules and glomeruli, for example, inflammation or dystrophy.

The preliminary outcome of treatment may be favorable, provided that the patient is diagnosed with a primary wrinkled kidney. Treatment with regular hemodialysis will lead to the development of chronic suburemia.

In their reports, doctors often indicate such a fact as a physiological change in the parenchyma (degeneration into connective tissue occurs).

Based on the clinical picture, a diagnosis is made: secondary wrinkled kidney.

Main types and reasons for their development

Primary nephrosclerosis

Sclerotic changes occur due to disruption of the functioning of the vessels feeding the cells of the paired organ. High pressure provokes spasms of blood vessels, as a result of which their elasticity and conductivity are lost. A primarily wrinkled kidney can result from:

• atherosclerosis;
• involutive sclerosis;
• hypertensive nephrosclerosis.

Atherosclerotic

Atherosclerotic nephrosclerosis is a disease that is not dangerous and responds well to treatment.
The pathology is a consequence of the formation and sedimentation of cholesterol plaques on the vascular walls. Due to the narrowing of the lumen of blood vessels, their elasticity and patency are lost. The kidney is insufficiently supplied with blood and nutrients and shrinks, resulting in ischemia. However, in this case, a small area of ​​the paired organ shrinks, so atherosclerotic nephrosclerosis is considered the safest.

Return to contents

Involutive nephrosclerosis

With this type of primary sclerosis, drying out of the kidneys occurs due to age-related changes; accordingly, the disease is diagnosed in the elderly category of patients. Due to the aging of the body, calcium deposits form on the arterial walls, which negatively affects the elasticity and conductivity of blood vessels. As a result, the kidneys are not supplied with blood and shrink, causing ischemia.

Return to contents

Hypertensive

The cause of the disorder is hypertension, which is characterized by vascular spasms that disrupt the normal blood supply to the kidney. As a result, a sclerotic change occurs and the parenchyma is replaced by connective tissues. Hypertensive nephrosclerosis or nephroangiosclerosis has its own subtypes:

• benign arteriolosclerotic;
• malignant arterionecrotic.

Return to contents

Secondary

Tuberculosis may be one of the causes of secondary nephrosclerosis.
The pathological change in this form of the disease concerns tissue damage to the paired organ, which occurs as a result of complications of various diseases that are inflammatory and dystrophic in nature. A secondary wrinkled kidney is a complication of the following pathologies:

• tuberculosis;
• glomerulonephritis;
• chronic pyelonephritis;
• amyloidosis;
• diabetes;
• nephropathy;
• formation of kidney stones;
• infarction of a paired organ.

What are the complications and consequences

A non-functioning kidney has an extremely negative effect on the entire body. Adverse complications include:

1. Untreatable arterial hypertension with inexorable disruption of the heart and blood vessels;
2. A rapid increase in renal failure, when it is necessary to find a donor as quickly as possible in order to save the patient’s life.

A partially wrinkled kidney can perform its functions for a long time without any dangerous consequences, but it is impossible to accurately determine when it will enter the terminal stage with a poor prognosis for life.

Characteristic symptoms of a shriveled kidney

Sclerotic renal pathology is insidious in that at the very initial stages it does not manifest itself in any way.

The patient learns his diagnosis by chance, during a routine medical examination. Even if the symptoms are not yet bothersome, it is still important to begin treatment immediately. Otherwise, the desiccation will progress, and kidney failure will gradually develop, the worst outcome of which is the death of the patient. Therefore, if the kidneys are wrinkled, it is important to pay attention and take action with the following symptoms:

• swelling of the face and limbs;
• nagging and aching pain on the right or left side of the lower back;
• increased blood pressure, accompanied by headaches that cannot be relieved by conventional means;
• increased urge to urinate;
• changes in the composition, color and smell of urine;
• irresistible thirst;
• aversion to meat dishes;
• disturbance of general well-being;
• lack of appetite;
• weight loss;
• Iron-deficiency anemia.

What are the signs of kidney drying out?

Symptoms of nephrosclerosis depend on the stage of the disease. They are divided into 3 - single, moderate and pronounced changes in tissues.

At the last stage of kidney nephrosclerosis, when their performance decreases, the following symptoms appear:

• pain in the lower back,
• renal colic - cramping pain in the lower back,
• increase or decrease in daily urine volume,
• hyperthermia (fever) due to a bacterial infection,
• the appearance of blood in the urine.

Diagnostic measures

An ultrasound of the kidneys makes it possible to assess how much the kidney has shriveled.
Renal sclerosis must be diagnosed promptly and correctly. Therefore, if characteristic symptoms are present, one or both kidneys hurt, it is important to visit a nephrologist and undergo a series of diagnostic tests. First of all, the patient will be prescribed clinical tests of urine and blood, and it is also necessary to submit a sample for a biochemical study of blood plasma. Using instrumental measures, the degree of organ damage, structural changes and the presence of concomitant pathologies are determined. Prescribed:

• Ultrasound diagnostics, which can be used to assess how wrinkled and deformed the kidneys are;
• X-ray of the pelvic organs;
• angiography;
• CT or MRI, which can also identify a malignant process.

What treatment is prescribed?

Before starting drug and auxiliary therapy, the pathological anatomy of the disease is studied in detail, then a treatment regimen is selected, and a specific diet is prescribed. In severe cases, the doctor decides to perform surgical intervention, but first they try to cure the disease conservatively.

Traditional

At the initial stages the following is prescribed:

The use of sorbents at the first stage of nephrosclerosis brings positive effects.

• anticoagulants - Heparin;
• potassium-containing drugs - “Asparkam”;
• antiplatelet agents - "Trental";
• multivitamins;
• iron-containing medications;
• sorbents.

Secondary kidney shrinkage is treated by eliminating the root cause of the disorder. In the later stages, drug therapy does not bring the desired effect; in this case, hemodialysis or an operation that involves organ transplantation is prescribed. This is a difficult procedure, which is performed only in the most advanced and hopeless cases, the outcomes of which are unfavorable.

Folk remedies

Before you decide to start using traditional treatment, you need to consult a nephrologist, otherwise dangerous complications may develop that could cost the patient’s life. If the doctor does not mind, you can try to relieve unpleasant symptoms and alleviate the condition using the following means:

Taking rose hips in the form of tea or infusion will help cure the disease.

• infusion of licorice root or lingonberry fruit;
• Birch juice;
• rosehip decoction;
• alcohol tincture with the addition of aspen buds.

Healthy diet

In addition to treatment with medications and folk remedies, it is also important to monitor nutrition, in particular, in case of kidney pathologies, it is primarily recommended to limit protein foods and diversify the diet with plant, fermented milk and dairy foods. You should eat regularly, but little by little, salt your food to a minimum, and don’t get carried away with spices and food additives. In case of cardiovascular disorders, it is important to control the amount of fluid you drink, but if there are no heart problems, then you need to drink at least 2 liters per day.

Recovery prognosis

A wrinkled kidney is characterized by a long course with periods of remission and exacerbation. Tissue necrosis is an irreversible process; they cannot be restored. However, timely therapy allows you to compensate for the function of the organ.

When diagnosing nephrosclerosis in the initial stages, the outcome of the disease is favorable: it is possible to restore the functioning of the kidney and blood flow in its tissues.

With a malignant form of nephrosclerosis and large areas of renal tissue degeneration into connective tissue, the prognosis is less favorable. Hemodialysis or surgical removal of the damaged organ is necessary. Timely surgery increases the chances of recovery for nephrosclerosis, since a healthy kidney compensates for the functions of the removed one.

Preventive actions

To reduce the chances of developing kidney nephrosclerosis, it is first of all important to start monitoring your health, lifestyle and diet, which significantly affects the condition of the paired organ and the development of pathological disorders in it. It is important to undergo routine, preventive examinations, treat diseases in a timely manner, and in case of suspicious symptoms, do not self-medicate, but go to see a doctor, find out the cause, and begin to eliminate it. The earlier kidney disease is diagnosed, the greater the chance of a successful and rapid recovery.

Forms of development of pathology

There are two main forms of the disease, namely:

Primary kidney shrinkage is a form that develops due to damage to the renal vessels. It can occur with arterial hypertension, the main manifestation of which is a strong increase in blood pressure.

Secondary kidney shrinkage is a form that develops due to damage to the renal parenchyma as a result of the development of various pathologies, for example, as a result of kidney damage by glomerulonephritis, etc.
