For a true assessment of the patient’s body condition, the doctor can use not only the usual clinical studies, but also more highly specialized ones, for example, urine analysis according to Nechiporenko. The norm in this analysis differs significantly from the indicators of a normal urinalysis, because during its analysis the cellular composition of the urinary sediment is analyzed. In this case, the doctor gets the opportunity to assess the true condition of the kidneys and determine the place and phase of the inflammatory process - in acute and chronic inflammation, the indicators differ significantly.
Urine analysis according to Nechiporenko - quick and accurate result
The study of the cellular composition of the urinary sediment obtained by centrifugation was proposed by the Russian (Soviet) physiologist and nephrologist A.Z. Nechiporenko. The norm indicated in the form takes into account the presence of red blood cells (erythrocytes), white blood cells (leukocytes) and special formations - cylinders that form from a heterogeneous protein in the glomeruli of the cortical apparatus of the kidneys. A feature of this study is the fact that all these elements are examined not in the total volume of urine delivered to the laboratory, but in a very limited amount of it - 1 ml.
For the test, the total amount of urine received after a regular genital toilet or cystoscopy with a catheter should be mixed well. 5-10 ml of material for centrifugation is taken from the total volume, after which only 1 ml of the liquid located at the bottom of the tube is subjected to analysis - the rest of the urine is drained. Accordingly, urine according to Nechiporenko, the norm of which is indicated in the form for analysis, more accurately demonstrates the condition of the kidneys and urinary tract, because in this test the correction is made that the amount of urine excreted in various types of pathology can vary significantly.
The examination process itself takes a relatively short time. This test is prescribed if changes in the routine clinical analysis of urine are detected, or vice versa, the results of generally accepted examinations remain unchanged, and the patient's condition has signs of one or another pathological condition of the urinary system. That is why you need to remember that the analysis of urine according to Nechiporenko, the norm of a clinical study of urine and the indicators of analysis according to Addis-Kakovsky differ. So, in a urine clinic under sediment microscopy, the cylinders are not normally found at all, and the number of red blood cells and white blood cells is much lower.
When a Nechiporenko analysis is necessary
Urine analysis according to Nechiporenko, the norm and deviation as a result of it, possible diseases and their stage - all these questions should be answered only by a qualified doctor, most often a urologist, nephrologist or therapist. Attempts to independently establish a diagnosis only by the results of only laboratory studies without taking into account the clinical picture of the disease (the totality of all symptoms and syndromes) most often lead to the fact that treatment is ineffective.
Even if the patient was previously diagnosed and treatment was prescribed that brought the expected effect, it cannot be guaranteed that at the moment the patient is concerned about the same pathological process. That is why a doctor who prescribes a urinalysis according to Nechiporenko, whose norm remains unchanged at any age periods of a person’s life, will be able to correctly evaluate the result, make a diagnosis and prescribe treatment or recommend a program for further examination.
The diagnostic value of urinalysis according to Nechiporenko is a quick opportunity to get an accurate result. The use of research to monitor the effectiveness of the treatment and the relatively low cost of execution make this diagnostic test popular with doctors and their patients.
