indication for the study are: diagnosis of acute and chronic diseases of the urinary system (UTI, cystitis, pyelonephritis, glomerulonephritis);dynamic monitoring of the course of the disease;monitor the effectiveness of treatment and others.
To analyze the need to collect an average morning urine.After morning toilet hygiene external genital organs patient begins to urinate in a glass jar first, then continues into a second sterile container and ends in the third.All containers should be clean and sterile.The largest amount of urine should be in the second pot.The resulting portion of urine is poured into the vacuum tube (special tube holder for urine
sampling).It can be purchased at a pharmacy or obtain prior to the study in the diagnostic center.
in clinical-diagnostic laboratory service analysis is carried out for 24 hours at a temperature of +2 to 24.The period of study is 1.5-2 hours.In the analysis of urine by Nechiporenko physician assistant determines the number of white blood cells, red blood cells and the cylinder using a special counting chamber.Standards of urine in adults: leucocytes - no more than 2000 in 1 ml of urine;erythrocytes - not more than 1,000 in 1 mL of urine;cylinders - not more than 20 per 1 ml of urine.The doctor evaluates the test results, diagnoses, if necessary, appoint additional research and selects a course of treatment at diagnosis.
for differential diagnosis of glomerulonephritis and pyelonephritis is important to clarify the degree of predominance leukocyturia or hematuria.As a rule, chronic or acute pyelonephritis in the urine within a patient is determined by a significant increase in the prevalence and the number of leukocytes.Patients with glomerulonephritis predominate erythrocytes in urine.Increasing the number of cylinders is found in diseases such as hypertension, heart disease, heart failure, gout, and others.
