Urinalysis by Nechiporenko: the norm differs from the clinical trial
For a true assessment of the patient's conditionthe doctor can use not only the usual clinical studies, but also more narrowly specialized, for example, urine analysis according to Nechiporenko. The norm in this analysis differs significantly from the results of an ordinary urinalysis, because during its analysis the cellular composition of the urinary sediment is analyzed. In this case, the doctor is able to assess the true state of the kidneys and determine the place and phase of the inflammatory process - in acute and chronic inflammations, the indicators vary significantly.
Urinalysis by Nechiporenko - fast and accurate result
Study of the cellular composition of urinary sediment,obtained by centrifugation, was proposed by the Russian (Soviet) physiologist and the nephrologist A.Z. Nechiporenko. The norm indicated in the form takes into account the presence in the urine of red blood cells (erythrocytes), white blood cells (leukocytes) and special formations - cylinders, formed 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 - 1 ml.
For the test, the total amount of urine,obtained after a normal toilet of genitals or cystoscopy with a catheter, should be well mixed. From the total volume, 5-10 ml of centrifugation material is taken, after which only 1 ml of liquid at the bottom of the tube is analyzed, the rest of the urine being drained. Accordingly, urine according to Nechiporenko, the norm of which is indicated in the form for analysis, more accurately demonstrates the state of the kidneys and urinary tracts, because in this test an amendment is made to the fact that the amount of urine released during various pathologies can vary significantly.
The survey process itself is relativelysmall time. This test is prescribed if changes are detected in the routine clinical analysis of urine, or vice versa, the results of conventional examinations remain unchanged, and the patient's condition shows signs of a certain pathological condition of the urinary system. That is why it is necessary to remember that the analysis of urine according to Nechiporenko, the norm of clinical urinalysis and the indicators of the analysis for Addis-Kakovsky differ. So, in the urine clinic, with microscopic sediment, the cylinders are not normally found at all, and the number of erythrocytes and leukocytes is much lower.
When the execution of the Nechiporenko analysis is compulsory
Urine analysis by Nechiporenko, norm and deviation inthe 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 establish an independent diagnosis on the basis of the results of only laboratory studies, without taking into account the clinical picture of the disease (a combination of all the symptoms and syndromes) often lead to the fact that the treatment is ineffective.
Even if the patient had previously been diagnosedand treatment was prescribed, which brought the expected effect, it can not be guaranteed that at the moment the patient is concerned about the same pathological process. That is why a doctor who prescribes a urine test for Nechiporenko, whose norm remains unchanged at any age of a person's life, will be able to correctly evaluate the result, diagnose and prescribe a treatment or recommend a program for further examination.
Diagnostic value of urinalysis byNechiporenko is a quick opportunity to get an accurate result. Using a study to monitor the effectiveness of the treatment and the relatively low cost of doing make this diagnostic test popular with doctors and their patients.
