title: [Clinical assessment of patients with microscopic hematuria pointed out by mass screening examination].
abstract: We clinically examined 445 patients with positive urine occult blood test found by mass screening examination. Among them, 41 cases had the history of macroscopic hematuria. Urological abnormalities were observed in 169 (41.8%) of the patients with microscopic hematuria, and in 22 (53.7%) of those with a history of macroscopic hematuria. Genitourinary neoplasms were found less frequently in the patients with microscopic hematuria (1.2%) than in those with macroscopic hematuria (22%). We couldn't find a correlation between the degree of hematuria and the severity of the underlying diseases. Hematuria is often thought to appear intermittently, and urinalyses of the patients with so-called significant disease may not be found at the first visit.
