Urethral stricture after transurethral resection.

After 101 transurethral resections, iatrogenic postoperative urethral strictures have occurred in 10 cases due to pathologic changes in the bladder and bladder neck. Urethral stricture after transurethral resection (TUR) thus has represented the most common postoperative complication. No morbidity increase of urethral strictures after TUR could be demonstrated in one of the analysed groups. Fifty per cent of the incidence rate of strictures was localized in the pars pendulans urethrae. Factors causing the stricture have been demonstrated, and the incidence rate of strictures was reduced when these factors were taken into consideration. Preference is given either to conservative or surgical therapy depending on the localization of the stricture, even though endoscopic methods are used more frequently now in the treatment of stenoses of the urethra.
