Drapkina, O M; Samorodskaya, I V; Larina, V N

The review article presents data on: a) definition of microhematuria and diagnosis; b) prevalence estimation and causes of the asymptomatic microscopic hematuria; c) diagnostic approaches for the first time identified of microhematuria; d) follow-up monitoring of patients with asymptomatic hematuria; e) feasibility of medical screening for microhematuria. The analysis includes recommendations of Russian and foreign urological associations, the results of cohort and observational studies, previous study reviews. The identification of 3 or more red blood cells during microscopic examination should be considered microhematuria. There is no uniform examination algorithm for all patients. The basic principle is an individual diagnostic tactic, taking into account the anamnesis, age, concomitant diseases and risk factors. The purpose of a comprehensive examination is to exclude life-threatening conditions (malignant neoplasms and/or glomerular kidney damage). In some cases, after research, the cause of microhematuria remains unclear and monitoring is required. Routine screening of the population in order to detect microhematuria is currently not justified.
