OBJECTIVE: The aim of this study was to evaluate outcomes and possible risk factors for failure of open urethroplasty due to penile urethral strictures. MATERIALS AND METHODS: A retrospective chart review was undertaken of 90 patients with penile stricture undergoing 109 open urethroplasties between 2000 and 2011. In 80 urethroplasties, a one-stage procedure was performed: 68 of these had a pediculated penile skin flap, nine had a free buccal mucosal graft and three had a free skin graft. A two-stage procedure using buccal mucosa was performed in 29 urethroplasties. Failure was defined as when further urethral instrumentation was needed. RESULTS: The mean age in the one-stage and two-stage groups were 50 and 54 years, respectively. The success rates in the corresponding groups were 65% and 72%, with follow-up times of 63 and 40 months, respectively. Multivariable analyses disclosed body mass index (BMI) and previous urethral surgery to be significant risk factors for failure in the one-stage group. Failure over time significantly decreased during the study period. CONCLUSIONS: Both one- and two-stage penile urethroplasty demonstrated success rates in line with previous reports. Limited experience, high BMI and previous urethral surgery appear to be associated with less favourable outcome.
