集団検診で発見された顕微鏡的血尿の臨床的検討

Abstract

集団検診で発見された血尿を主訴に来院した症例は高齢になるほど, 尿路腫瘍の存在する率が高い.高齢者に対しては, 尿細胞診, 膀胱鏡, 腹部超音波検査, 静脈性腎盂造影を施行する必要があると考えられる

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.
