無症候性顕微鏡的血尿232例の臨床的検討

STUDY OF 232 PATIENTS WITH ASYMPTOMATIC MICROHEMATURIA

　無症候性顕微鏡的血尿を主訴とした患者で，検尿，尿細胞診，腎超音波，IVP，膀胱鏡のすべてを施行し得た232例を検討した。悪性腫瘍が3.4％（膀胱癌6例，腎癌1例，前立腺癌1例）で，これを含む泌尿器科的重要疾患が6.0％で発見された。重要疾患の発見率は男性で有意に高かつたが，血尿の度合には影響されなかつた。何らかの泌尿器科的異常を48.3％の症例で認めたが，血尿原因を指摘し得たのは15％未満であつた。今回の検討より，成人の無症候性顕微鏡的血尿患者には，尿細胞診，腎超音波，IVPを，そして40歳以上の際は膀胱鏡，前立腺触診も加えて施行すべきと考えられた。また当初の検索で著変を認めない場合の経過観察法についても考察した。

To evaluate the clinical significance of microhematuria, 232 patients with asymptomatic microhe-maturia who had undergone complete urologic examination were reviewed. Highly significant urologic lesions were found in 6.0% of all patients, with 16.4% in men and 2.3% in women. Genitourinary neoplasms were found in 3.4%(6 bladder cancers, 1 renal cell cancer and 1 prostatic cancer). Overall urologic abnormalities were identified in 48.3% of patients, but the lesions which represented a firm explanation for microhematuria were seen in less than 15%. We could find no relationship between the degree of hematuria and the cause.
