[A clinical study of 80 endoscopic urethrotomies: an investigation of factors influencing recurrence].

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.
