Urethroplasty for treatment of long anterior urethral stricture: buccal mucosa graft versus penile skin graft-does the stricture length matter?

Purpose: To investigate the surgical outcomes of dorsal onlay urethroplasty (DOU) using buccal mucosa graft (BMG) or penile skin graft (PSG) and to assess the effect of stricture length in men with anterior urethral strictures.

Methods: A prospective cohort included men with anterior urethral strictures between 2008 and 2015. Patients underwent DOU using PSG or BMG.
