Iatrogenic prostatic urethral strictures: classification and endoscopic treatment.
OBJECTIVE
The treatment of posterior urethral strictures is a controversial subject. For proper treatment, it is important to differentiate between iatrogenic prostatic urethral strictures and post-traumatic membranous urethral strictures.


METHODS
Iatrogenic strictures of the prostatic urethra have been classified according to location and etiology into three categories: type I, located exclusively at the bladder neck; type II, located in the midportion of the prostatic fossa; and type III, when the whole prostatic fossa is replaced by stricture. From 1970 to 1996, 163 patients with postoperative strictures of the prostatic urethra were treated endoscopically.


RESULTS
The results obtained in 122 patients are reported; 41 patients are not evaluable. The median follow-up was 63 months (range 12 to 239). Seven patients required a second endoscopic procedure to attain cure. Good results were achieved in 54 (91%) of 59 patients with type I strictures, in 45 (98%) of 46 patients with type II strictures, and in 13 (76%) of 17 patients with type III strictures. The overall success rate was 92% (112 of 122). Complications occurred in 21 patients (17%), including postoperative urinary tract infection (11%), incontinence (4%), stress incontinence (1%), and severe bleeding (1%).


CONCLUSIONS
Postoperative strictures of the prostatic urethra must be recognized and can be easily treated with endoscopic therapy.
