[Urethral stricture after TURP and transvesical prostatectomy].

In an attempt to elucidate factors predisposing to the occurrence of urethral stricture after transurethral resection of the prostate, we performed a prospective follow-up of 178 patients over 12-20 months. We took account of 11 factors that we considered important. Urethral strictures developed in 14.04% of the patients. The resection operations were carried out by five different surgeons, who had different rates of stricture. The only one of the 11 factors studied that was found to involve a statistically significant risk was the presence of an indwelling catheter for more than 3 days. No other factor influenced the result. This patient group was compared with a group of 73 patients followed up for 12-60 months following transvesical prostatectomy. In this group only one stricture (1.36% incidence rate) was observed retrospectively. It seems that urethral ischaemia might increase the risk of urethral stricture. Urethral injuries are considerably less frequent with open prostatectomy. Therefore, we recommend transvesical prostatectomy for pronounced prostatic hyperplasias.
