緒言
尿道狭窄の外科的療法が成功したかどうかの判定,あるいは不幸にして狭窄が再発した場合にどの時期に苦痛の多い尿道拡張術を行なうかについては判断に迷うことが多い。
われわれは14例の尿道狭窄患者に尿流量測定(Uroflowmetry以下UFMと略す)を行ない,予後判定や尿道拡張術を行なう時期の決定にUFMが非常に有効な方法であるという結論を得たので報告する。
Fourteen male patients with urethral stricutres were studied by uroflowmetry, retrograde urethrogram and subjective condition of urination. Maximum flow rate (MFR), which was carried 7 times pre-operatively, was 2-10 ml/sec (5. 3 ml/sec average). MFR, which was carried 22 times postoperatively, was 8-32 ml/sec (16 ml/sec average). In all cases, MFR was improved after operation.
Postoperatively, MFR was less than 10 ml/sec in 3 cases, however we could not find stricture by urethrogram, and subjective condition of urinary flow was good in 2 of them.
