Kidneys—structure, membranes, fixing apparatus. Topography of the kidneys. Blood supply to the kidney. The structure of nephrons, their types.

Phonation of the kidneys is the effect on the organ of vibrations that have a certain amplitude. They have a positive effect on the human body. After this, patients noted that the functioning of many systems had returned to normal.

As for medical research, they also indicate a positive result. In particular, there is an improvement in the process of excretion of uric acid by the kidneys. Since the achieved therapeutic effect lasts for several hours, more than one procedure must be done per day, but positive changes are visible already after the first session.

If you understand why phonation of the kidneys has a positive result, then you need to turn to such a nuance as the cellular nature of the occurrence of certain pathological conditions. The fact is that many diseases actively develop with an increased content of dead cells in organs.

It does not matter what caused their death. However, if the immune system has not worked properly and they have not been eliminated from the body, it will not have the opportunity to regenerate new cells. Accordingly, there is an increase in the number of those elements that are already necrotic.

Thanks to phonation of the kidneys, the process of removing dead cells from the body improves. When performing the procedure, certain conditions are created under which the necessary substances move through the tissues and capillaries. Yes, the body has an identical process of its own, but its resource is limited, therefore, in the event of the development of pathology, the period of regeneration of healthy cells increases its duration.

It is due to microvibrations that the following processes occur in the body:

  1. Outflow of venous blood and lymph;
  2. Restructuring of cell mass during the regeneration period;
  3. Delivery of nutrients to cells;
  4. Removing unnecessary toxins and breakdown products;
  5. The progeny of stem cells is improved.

The main filtration organ, naturally, is the kidneys. Unfortunately, due to their anatomical features, they lack muscle cells, but at the same time they especially need microvibrations. Phonophonation helps compensate for this, and it is performed with a special device - a vibraphone, which is located in the area of ​​the muscular wall of the pelvis.

Why is the kidney called “dumb”

The term “silent kidney” was coined by radiologists. Experts use this phrase in cases where, based on the results of excretory urography, one of the organs does not function and, naturally, does not cope with the main task - the release of toxic substances and fluids from the body.

Clinically, a dumb kidney does not manifest itself in any way. It can be in the body for a long time, and the patient does not even realize that only one is functioning. In many cases, a silent kidney is an incidental finding during an examination for another reason.

You should know that a silent kidney is not a disease, but only a complicated consequence of it. This condition can provoke various congenital and acquired diseases of the excretory system.

Restrictions and contraindications

Kidney scintigraphy is contraindicated for patients in serious condition, since the procedure lasts up to 2 hours, it will be difficult for a person to withstand such a time. Diagnostics is contraindicated during pregnancy and during feeding, because the contrast has radiation properties. But in case of urgent need, after scintigraphy and administration of the drug, you will need to stop breastfeeding for a day.

It is contraindicated to undergo scanning after a course of chemotherapy and radiation exposure. Nephroscintigraphy is contraindicated in patients who have undergone major surgery, since when contrast is administered, a lot of fluid will accumulate in the kidneys, and this is dangerous. Scintigraphy should not be used in patients who have developed an allergic reaction to a radionuclide. Under other circumstances, the diagnostic procedure does not pose any danger or discomfort.

What is the danger?

If a person’s one kidney does not work, and the other is absolutely healthy, then, in principle, there is no danger. A healthy organ takes on its own load and copes well with the function and task of its “neighbor”.

There is a danger of developing an infection (cystitis, pyelonephritis), which can get into the hollow part of a non-functioning kidney. As a result, purulent inflammation may develop. It also happens that complete purulent melting of the kidney tissue occurs with the appearance of a large abscess, which can rupture at any moment and the pus infects the organs and tissue of the abdominal cavity, as well as the retroperitoneal space. This condition requires emergency surgery to save a person's life.

The decision to remove this organ must be made only by a doctor. If the risk of developing an infection is small, then it is not touched; it can remain in the body for a long time without causing harm. If the patient has a fairly high level of infection, then the silent kidney is then eliminated surgically so that there are no complications.

Methods and methods of treatment depend on the cause of the pathology, the presence of risk factors for its infection, and the condition of the second kidney.

You need to understand that it is simply impossible to cure a dysfunctional organ. The only exceptions are cases when very little time has passed since the loss of its functionality. Then a surgical operation that eliminates the cause can still save the organ. For example, an organ injury with a violation of its integrity or a stone clogs the ureter.

It is important! It is useless to treat a dumb kidney if it does not function for a long time. In such situations, there are two options: firstly, surgical removal of the silent kidney for prophylactic purposes, and secondly, wait-and-see tactics with constant medical examinations.

If both organs stop working in a person, then the only chance to save life is surgery to transplant a donor organ.

Removing a silent kidney is called a nephrectomy. The operation can be carried out in several ways:

  1. Laparoscopic surgery is a minimally invasive surgical method that helps remove the organ through three small punctures made in the anterior abdominal wall.
  2. Lumbar approach - an incision is made in the lumbar region and the kidney is eliminated, bypassing the abdominal organs.
  3. Cavitary access - the anterior abdominal wall is cut and the organ is removed.

Kidneys are a vital organ, without which a person cannot live even three days. The main function of this paired organ is to cleanse the blood of harmful, toxic and unnecessary substances for the body, get rid of excess fluid, maintain a stable acid and electrolyte composition of the internal environment of the body (homeostasis). Also, the kidneys perform other, no less important, tasks. Kidney cells secrete hormonal substances that affect the production of erythrocytes (red blood cells) by the bone marrow, regulate blood pressure levels, and the formation of vitamin D and other essential substances for life.

The compensatory capabilities of the human body are impressive. Thus, a person can live his entire life with only one kidney (congenital absence or loss of function of the second organ) and not even suspect it. The answer to the question of whether life is possible with one working kidney is clearly positive. Life with one kidney is absolutely no different from the life of people who have two, provided it is healthy. Therefore, if you only have one kidney, you need to take care of its well-being.

How to Maintain a Healthy, Functioning Kidney

If it happens that a person is found to have one non-functioning kidney, there is no need to fall into a depressive state; one should take care of the health of the second (healthy) kidney in order to live a full life. Therefore, it is very important to keep your functioning kidney healthy. There are some rules to follow.

It is necessary to protect yourself from colds, take a specially selected complex of vitamins, and antiviral medications during epidemics. Don't forget about the flu shot. If the first signs of a cold appear, you should stay at home and stay in bed, and do not suffer the disease on your feet.

If suddenly such a misfortune happens to you, and you find out that one of your kidneys is not working, there is no need to lose heart. After all, the capabilities of the human body are limitless. Many people live full lives with only one organ. And there are people who do not even know about such a problem in their own body, if the second one is healthy.

Basic diagnostic techniques

There are several types of renal scintigraphy:

  • nephroscintigraphy;
  • renoscintigraphy;
  • Circuloscintigraphy.

Renal nephroscintigraphy is performed dynamically or statically. Static nephroscintigraphy is carried out after an X-ray examination, which reveals the main parameters of the kidneys:

  • location;
  • dimensions;
  • the presence of pathological changes.

Static renal scintigraphy is an additional examination method. The method does not provide a comprehensive picture of functional disorders and the presence of pathological changes in the kidneys.

Dynamic nephroscintigraphy is performed after the patient has been administered a radiopharmaceutical. The scanner records the entry of the radioactive drug into the kidneys and the movement of the RPF within the urinary system at certain intervals. All changes occurring in organs during manipulation are recorded. Dynamic kidney scintigraphy makes it possible to see step by step all the processes of urination as a whole and to study in detail the work of each organ.

Kidney failure: symptoms, signs, what to do and how long to live?

The kidneys in the human body perform a function that other organs cannot do - they regulate homeostasis or, to put it simply, they filter blood and plasma and remove urea. Also, these organs contribute to the removal of end products of nitrogen metabolism, toxic compounds, and participate in carbohydrate and protein metabolism.

Violation of the excretory function of the kidneys entails a number of consequences that can significantly harm health, and sometimes even lead to death.

What can cause kidney failure?

Impaired kidney function occurs with renal failure - acute or chronic. The main difference between these forms is the period from the onset of the disease to the appearance of the first signs:

  1. Acute renal failure (ARF) develops within a matter of hours or days. The cause of the disease is a violation of water, acid-base, electrolyte, osmotic balance. These changes are reversible because they are ischemic or toxic in origin.
  2. A sharp drop in the number of active nephrons (cells that are responsible for cleansing organs) indicates the development of chronic renal failure (CRF).

    This provokes poisoning of the kidneys with its own waste products, which the organs were unable to remove.

    In the initial stages of the disease, healthy organ tissues are forced to work for themselves and for those parts of the kidneys that are unable to function.

    This creates an overload of healthy parts of the organs. This leads to even greater disruption of the kidneys. The disease is chronic, so not all symptoms appear immediately, which greatly complicates the diagnosis of the disease. If chronic renal failure is not detected in time, complete organ failure may occur.

Doctors are of the opinion that impaired renal function manifests itself as a consequence of such conditions of the body:

  • Renal failure - problematic functioning of the renal parenchyma. The causes of this condition may be: thrombosis of blood vessels;
  • glomerulonephritis (acute stage);
  • renal infarction;
  • intoxication of the body of various origins;
  • intense organ trauma.
  • Prerenal insufficiency, which occurs as a result of circulatory failure in the patient’s body. A critical drop in blood pressure can be caused by:
    • severe blood loss as a result of injuries;
    • sepsis;

  • anaphylactic shock;
  • burns;
  • disorders of the heart.
  • Postrenal insufficiency, the development of which is caused by obstruction of the urinary tract. The causes of kidney failure, in this case, are:
    • malignant formations;
    • hematomas of various origins;

  • kidney stones.
  • Severe symptoms of kidney failure

    Kidney failure is a disease in which healthy cells take over all the work done by the kidneys. This compensates for the inactivity of dead tissue.

    A person can continue to live normally, without feeling intoxication in the body and without suspecting how poorly the kidneys are working.

    But over time, it becomes increasingly difficult for healthy organ tissues to perform their functions, given the heavy loads, the excretory process is disrupted.

    If a patient drinks alcohol or takes medications that can release toxic compounds into the body, functioning cells begin to die en masse, unable to withstand the harmful effects.

    At the first stage of the disease, the following symptoms of kidney failure appear in a person:

    • sleep disorders;
    • constant fatigue;
    • headache;
    • strong thirst;
    • formation of edema.

    Signs of kidney failure in acute renal failure:

    • urine output becomes partial or stops completely;
    • severe swelling of the face and ankles appears;
    • the patient gains weight;
    • attacks of nausea accompanied by vomiting;
    • skin itching;
    • there is blood in the urine;
    • a foul odor is felt from the patient’s mouth;
    • Chronic weakness and malaise develop.

    Having noticed the symptoms of acute renal failure, you must immediately consult a doctor and begin appropriate treatment, otherwise the patient’s lungs will fill with fluid, resulting in shortness of breath, drowsiness, and periodic clouding of consciousness. Hematomas that appear on the body will provoke massive internal bleeding.

    Most often, the outcome of such an advanced state is coma.

    Renal dysfunction associated with chronic renal failure has the following symptoms:

    • polyuria (excessive urine production as a result of problems with the urinary system);
    • frequent but scanty urination at night;
    • bad feeling;
    • formation of edema;
    • dyspnea;
    • loss of appetite, nausea ending with vomiting;
    • bad breath;
    • increasing pain in the chest area, as well as in the bones;
    • the skin is pale, often has a yellowish or even brown tint;
    • gums bleed;
    • amenorrhea (disruptions of menstrual function in women of childbearing age with a complete absence of menstruation for several months or longer);
    • formation of white urea crystals on the skin;
    • convulsive conditions, muscle spasms;
    • uremic coma (caused by intoxication of the body due to renal failure).

    Important! To avoid irreparable disturbances in the normal functioning of the kidneys, it is necessary to consult a specialist at the first symptoms.

    The alarming consequences of the disease

    In most cases, the development of acute renal failure results in necrosis of the renal cortex. It occurs due to long-term disruption of the blood circulation of these organs. Stagnation of blood serves as the basis for the formation of edema. In such a situation, there is a high probability of developing an infection.

    The situation is worse with the consequences of chronic renal failure. Uremic toxic substances, accumulating in the patient’s body, have a detrimental effect on the nervous system and cause convulsions. A person’s mental function is disrupted, and there is clouding of consciousness.

    Kidney dysfunction leads to anemia. It occurs as a reaction to a decrease in the level of erythropoietin, the hormone responsible for the formation of red blood cells. Hematological disorders become the basis for disruptions in the activity of leukocytes, so the risk of blood infections increases significantly.

    Kidney failure can lead to problems with the cardiovascular system - hypertension. But what is more dangerous is that strokes and myocardial infarctions provoked by this disease can occur.

    The patient's bone tissue is also subject to the harmful effects of chronic renal failure. As a result, osteodystrophy often occurs.

    The gastrointestinal tract suffers in its own way - due to loss of appetite and weight loss, anorexia may develop, and bleeding may begin in the stomach or intestines.

    Problems that accompany the course of the disease are also metabolic failures and the production of insufficient amounts of vital hormones.

    The natural reaction of the patient is the desire to get rid of the disease and return to life with healthy kidneys.

    The ability to restore functionality to these organs directly depends on the stage of the disease and the correctness of treatment.

    The earlier poor kidney function is diagnosed, the higher the chance of preserving and curing them. Therefore, at the first symptoms, the patient should consult a doctor.

    Prognosis for kidney failure

    How long can a person live if his kidneys fail is a question that can be answered by knowing all the nuances of a particular case of illness. It all depends on timely diagnosis and proper treatment.

    Another factor influencing life expectancy after failure of these organs is the ailments that precede this condition. We are talking about heart attacks, diabetes, damage to blood vessels and the heart.

    It happens that a patient dies after kidney failure due to other diseases.

    Modern medicine claims that a person suffering from this disease has a chance to survive if treatment is aimed at eliminating the causes of the symptoms and artificial blood purification (hemodialysis). There are cases where this procedure extended the life of patients by 20 years.

    If the functionality of the kidney cannot be restored using a conservative method, a donor organ transplant is necessary. This operation will help a person live more than 20 years. But, despite this opportunity, many people cannot undergo a transplant - the likelihood of finding a donor is low, and most patients simply cannot afford to pay for a transplant.

    Kidney failure is a disease that modern medicine can successfully combat. But this is only possible when the disease is diagnosed in time, and this is where difficulties arise in most cases.

    Every person should understand that the ability of organs to recover is not limitless. Therefore, it is necessary to pay special attention to the occurrence of symptoms of diseases - timely changes in the activity of individual organs sometimes not only prevent serious health problems, but also prolong a person’s life.

    Symptoms of kidney failure

    When the kidney is not working well, symptoms can vary. One of the serious diseases, the signs of which must be paid attention to, is kidney failure. The main symptom is severe renal colic. Usually, in this condition, patients immediately consult a doctor, since the colic is severe and painful. How can we explain this malaise? Stones come out of the renal pelvis, they clog the ureters, begin to seriously injure the walls, all this causes quite strong pain that is impossible to tolerate.

    With renal failure, all the ureters begin to contract, the outflow of urine is disrupted, and the nerve endings in the renal pelvis and walls of the urinary tract begin to be irritated.

    In addition to colic, the following symptoms also appear:

    1. Acute pain of the so-called cramping nature, they appear in the lumbar region.
    2. Spread of pain to the ureter area, lower abdomen, inner thigh. In women, pain occurs in the labia area, and in men - in the scrotum.

    An important sign is pain in the kidneys themselves. During colic, a patient cannot find a comfortable body position, the pain does not get better, blood pressure and body temperature rise. Painful sensations can become simply unbearable; a person in this state experiences nausea, a gag reflex, dizziness, and an unpleasant urge to urinate. Blood clots appear in the urine.

    After the colic subsides, sand and small stones begin to be excreted in the urine.

    Painful sensations can last from a few minutes to 3-5 hours.

    Symptoms of kidney disease can vary. They are divided into local and general, but are almost always accompanied by severe pain. When the first signs of the disease appear, you need to consult a doctor for examination. An advanced disease can lead to serious consequences; this should not be allowed.

    Signs of glomerulonephritis

    Glomerulonephritis is an infectious-allergic pathology. This disease has several forms; the main symptom is the presence of blood in the urine. In the acute form, urine may not be excreted at all, and anuria occurs. During the examination, protein and a large number of leukocytes are detected in the urine. Usually both kidneys are damaged at once, rarely only one is affected.

    All symptoms of the disease occur against the background of general metabolic disorders. The water-electrolyte balance of the body changes, the elimination of salts is also carried out with disturbances, and arterial hypertension occurs. A lot of protein is lost in the urine, this provokes severe swelling, and dropsy can be diagnosed.

    In severe forms, serious complications can occur - swelling of the brain and even the lungs. Moreover, local symptoms in this case are weak. There is almost no pain, there are no significant changes in urination. If signs of this disease appear, you should never self-medicate, as this can lead to disastrous consequences. If the disease is advanced, then surgical intervention cannot be avoided; organ removal is possible.
