Analysis of the factors involved in the failure of urethroplasty in men

Abstract

Outcome of urethroplasty techniques in our environment and risk factors for recurrence of stenosis in these patients are studied in this paper.

Retrospective study on men with urethral strictures treated with urethroplasty in the period 2000–2012. Maximum flow (Qmax), post-void residual (PVR) urine and patient perception of voiding were obtained pre- and postoperatively. Complications were recorded according to the Clavien-Dindo scale. Recurrent stricture was defined according to clinical criteria and endoscopic or imaging confirmation (failure of urethroplasty). Univariate analysis (log-rank) and multivariate (Cox regression) analysis were performed to define the variables implied in the recurrence.
