Urethral stricture complicating transurethral prostatic surgery.

The incidence of urethral stricture was 9 per cent among 336 patients after transurethral prostatic resection for benign hyperplasia. The strictures were mostly in the penile part of the urethra and could be treated with regular dilation, internal urethrotomy or meatal incision. Bacteriuria or indwelling catheter preoperatively did not seem to predispose to stricture formation. When there is an indication of a narrow urethra before TUR, a fine-calibre resectoscope should be used and a preliminary internal urethrotomy is advisable.
