直視下内尿道切開術80例の臨床的考察--特に再発に関する考察--

Abstract

男子尿道狭窄80例に対して直視下内尿道切開術を施行した.1)3ヵ月から5年間経過観察し, 非再発率は43.2%であった.2)再発の時期は50%が3ヵ月以内に, 80%が1年以内であった.3)数回の手術により再発率が著しく低下した.4)外傷性尿道狭窄が炎症性尿道狭窄に比して有意に再発しやすかった.5)カテーテル留置期間に関しては4日留置例の再発が少なかった.6)狭窄の部位, 長さ, 径, 数に関する再発率には有意差がなかった

Internal urethrotomies under direct vision for urethral strictures were carried out in 80 male patients during the past 5 years. None of the patients died and morbidity was minimal. The immediate postoperative success rate was 96.3%. A retrospective review of results showed an overall cure rate of 43.2%. In the patients in whom the stricture recurred after the first operation, the recurrence was recognized in 50% during the first three months and in 80% during the first year. Repeated operations resulted in a significantly higher cure rate than the initial operation. The results were unrelated to the site, length, width, or the multiplicity of the stricture. However, the recurrence rate was significantly higher for traumatic strictures than inflammatory ones. The recurrence rate was lowest when the catheter was indwelling for 4 days.
