Direct vision internal urethrotomy. A critical review of 365 operations.

Internal urethrotomy under direct vision for urethral strictures in the male was employed on 369 occasions in 225 patients during a 4-year period. A retrospective review of results showed an overall cure rate of 77% but the cure rate after each individual operation was less than 50%. Operations for recurrence carried a significantly lower cure rate than initial operations but even after several recurrences there were reasonably good results considering the relatively minor procedure. An active post-operative follow-up employing routine urethroscopy showed significantly better results than mictiographic follow-up. The post-operative period of catheterisation and positive urine culture at the time of follow-up had no significant influence on the results.
