RESUMO
PURPOSE: To evaluate the interplay of stricture recurrence, sexual function, and treatment satisfaction after substitution urethroplasty. METHODS: Observational study of men undergoing 1-stage buccal mucosal graft urethroplasty for anterior urethral stricture between 2009 and 2016. Patients were dichotomized by self-reported treatment satisfaction. Sexual function was assessed by validated and non-validated patient-reported outcome measures. Functional recurrence was defined as symptomatic need of re-intervention. Bivariate analyses, Kaplan-Meier estimates, qualitative and quantitative analyses by uni- and multivariable regression were employed to evaluate the interplay of sexual function, functional recurrence, and treatment satisfaction. RESULTS: Of 534 men with bulbar (82%), penobulbar (11%), and penile strictures (7.3%), 451 (84%) were satisfied with the surgery. There were no differences in stricture location, previous treatment, graft length, or surgical technique between satisfied and unsatisfied patients (all p ≥ 0.2). Recurrence-free survival was 85% at a median follow-up of 33 mo and decreased significantly with each Likert item towards increasing dissatisfaction (p < 0.001). Dissatisfied patients more often reported postoperative loss of rigidity, tumescence, reduced ejaculatory volume, ejaculatory pain, and reduced penile length (all p ≤ 0.042). In 83 dissatisfied men, functional recurrence (28%) and oral morbidity (20%) were the main drivers of dissatisfaction in qualitative analysis. Multivariable analyses revealed functional recurrence and impaired postoperative ejaculatory function as independent predictors of treatment dissatisfaction (all p ≤ 0.029) after adjusting for confounders. CONCLUSION: We found an association of both functional success and sexual function with patient-reported treatment satisfaction after substitution urethroplasty. Such findings validate the clinical significance of defining the symptomatic need for re-intervention as an endpoint and underline the importance of further research evaluating sexual function before and after open urethral reconstruction.
