This type of urine examination was first proposed by the Soviet scientist Alexander Zakharovich Nechiporenko. This analysis allows you to clarify the diagnosis, confirm or refute the development of inflammatory diseases in the kidneys and other organs of the urinary system.

Features of the analysis

Urine analysis according to Nechiporenko is considered one of the most accurate and allows you to identify even hidden infections. In the course of its conduct, the sediment of 1 ml of biological fluid is examined and the content of leukocytes, erythrocytes and cylinders is detected in it. The analysis helps not only to diagnose pathology, but also to determine the degree of violations. He is appointed if:

  • when conducting a general analysis of urine, deviations from the norm were found;
  • it is necessary to clarify the preliminary diagnosis;
  • monitoring of the prescribed treatment or the performed surgical intervention is required.

This type of research is often prescribed during pregnancy.

It is necessary to pass the analysis correctly. 2 days before urine collection, spicy, salty, fatty foods, alcohol, as well as foods that can change the color of the biological fluid should be excluded from the diet. If possible, it is better to refuse to take antibiotics, diuretics, as this can distort the result significantly enough. When this is not possible, it is imperative to inform your doctor about the medications you are taking.

It is necessary to collect urine in the morning and preferably immediately after waking up. Before this, you should conduct a thorough hygiene of the external genital organs. Women cannot be tested during menstruation. For research, only the middle portion of urine is suitable. This means that you need to urinate in the toilet for 2-3 seconds and only then into the container. It is also necessary to complete urination outside the container. For the analysis, you will need 20-30 ml of urine. A child, especially a baby, cannot control the process of urination, therefore, in this case, it is permissible to take the entire volume of fluid for analysis.

A special sterile container with a screw cap is ideal for storing urine. It must be delivered to the laboratory no later than 2 hours after collecting the biological fluid.

Decoding the result

To decipher the result, it is necessary to compare the obtained values ​​with the normative ones. The following indicators are considered the norm:

  • leukocytes - up to 2000 cells in 1 ml of urine;
  • erythrocytes - up to 1000 cells in 1 ml of urine;
  • hyaline cylinders - up to 20 cells in 1 ml of urine.

The content of only hyaline cylinders in the biological fluid is considered permissible. There should be no other forms. A high percentage of erythrocytes and leukocytes, the detection of various cylinder shapes, proteins, epithelial cells, bacteria and other types of microorganisms may indicate inflammation, infections or other pathologies of the organs of the urinary system. Urine analysis according to Nechiporenko suggests the presence of pathology, but a more accurate diagnosis should be made by a specialist based on other data.

An increase in the content of leukocytes in urine and an excess of the norm may indicate the development of:

  • kidney stones;
  • pyelonephritis;
  • prostatitis;
  • cystitis.

The higher the content of leukocytes, the more pronounced and neglected is the inflammatory process.

An increase in the concentration of red blood cells in the urine indicates a possible development:

  • urolithiasis
  • kidney failure;
  • acute glomerulonephritis (damage to the renal glomeruli);
  • nephrotic syndrome;
  • tumors;
  • kidney tuberculosis;
  • cystitis.

If more than 20 healin cylindrical cells can be found in 1 ml of urine, this may be caused by an increase in blood pressure, taking diuretics or pyelonephritis.The presence of granular casts in the urine indicates the possibility of the development of glomerulonephritis, pyelonephritis, viral diseases. This deviation from the norm is also observed with lead poisoning.

Detection of erythrocyte casts in urine is a reason to be wary. This is one of the signs of a kidney infarction or venous thrombosis. Waxy casts should also not be present in the urine. If present, it may indicate the development of nephrotic syndrome and renal amyloidosis. Detection of epithelial-type cylinders is a sign of an acute viral infection, damage to the renal tubules. The same symptom may indicate heavy metal poisoning.

To decipher the results of urine analysis and make a diagnosis, you need to take into account the data obtained during the collection of anamnesis. But more research is almost always required. This can be a blood test, ultrasound, or magnetic resonance imaging.
