Buccal mucosal grafts perform less favorably in a radiated setting after bulbar urethroplasty
By Kennedy Dirk, Seth Thomas and Keith Francis Rourke.
Abstract
Introduction
Buccal mucosal grafts (BMG) are the preferred tissue for substitution bulbar urethroplasty; however, it is unclear if BMG performs equally well across all stricture etiologies. The objective of this study was to examine etiology-specific outcomes of bulbar urethroplasty using BMG.
Methods
From September 2003 to May 2023, patients undergoing bulbar urethroplasty at a single center were evaluated. The primary outcome was stricture-free survival, with recurrence defined as stricture <16 Fr on followup cystoscopy. Secondary outcomes included 90-day complications (Clavien ≥2), patient-reported erectile dysfunction (ED), and satisfaction. Multivariable Cox regression analysis was used to evaluate variables associated with stricture recurrence, and Chi-squared test to assess secondary outcomes.
