title: Visual internal urethrotomy with postoperative cystostomy or urethral catheter.
abstract: Visual internal urethrotomy is nowadays considered by many to be a very useful method of treating urethral strictures. There is still controversy, however, about how long the postoperative urethral catheter should be left in situ. A prospective randomised study was therefore performed to evaluate the influence on the results of urethral catheterisation versus a suprapubic cystostomy for 5 weeks. After 12-36 months of follow-up (mean 25 months) there was a significant difference in result in favour of the urethral catheter. In the catheterised group, 13 out of 20 patients were without recurrence, compared to 4 out of 17 patients in the cystostomy group. Of the total number of 76 patients treated by postoperative urethral catheterisation, 37 (48%) had a normal or slightly subnormal flow-rate 12-60 months after the urethrotomy. Young patients and patients with stricture treated for the first time showed significantly better results than older patients or patients who had previously been treated twice or more. The stricture diameter-prestenotic urethral diameter ratio, obtained by combined retrograde and antegrade urethrography, provided a fairly accurate measure of the functional significance of a stricture.
