Close concept: blood in urine
Each patient with the hamaturia as expressed, and microscopic, demands careful inspection. In spite of the fact that at a hamaturia it is necessary to take a large number of various factors into account, the age and a sex of the patient, and also possible communication of a hamaturia with an injury first of all are important for definition of the direction and volume of research. So, the glomerulonephritis is the reason of a hamaturia at 40 — 50% of the children inspected concerning not traumatic macro - or microhematurias. Oncological diseases, first of all Vilms's tumor, and also a rhabdomyosarcoma of a bladder and prostate, are the uncharacteristic reasons of a hamaturia for this age group. To the contrary, new growths, both high-quality, and malignant, act as the most frequent reason of a hamaturia at the adult patients who are in a hospital while the glomerulonephritis in this age group is found infrequently. According to it in each section of the present article the hamaturia at adults, at children separately is considered and at injuries.
It is indisputable that the expressed hamaturia is the important symptom demanding serious inspection. However criteria of expressiveness of a microhematuria are not established. At children the diagnosis of a microhematuria is made in case of detection at microscopic examination of a tsentrifugat at big increase by more than 5 erythrocytes under review at least in 2 of 3 sequential analyses of urine. At adults such installation can lead to a diagnostic mistake as at a cancer of a bladder and kidneys of bleeding can periodically arise. In doubtful cases the doctor himself has to make microscopic examination of urine. If doubts remain, it is better to conduct careful laboratory and X-ray research, than to pass a serious disease of uric ways.
