Overview

Presence of >5 red blood cells (RBCs) per high-power microscopic field in the urine is called hematuria. It can have either benign or malignant etiology. Patients with hematuria could be asymptomatic. Therefore, all patients presenting with a single episode of haematuria require urgent investigation. Microscopic hematuria, or microhematuria (MH), is defined as the presence of RBC on microscopic examination of the urine not evident on visual inspection of the urine. The prevalence of MH among healthy participants in screening studies is 6.5% (95% confidence interval [CI] 3.4 to 12.2), with higher rates in studies with a predominance of males, older patients, and smokers.
