Substitution urethroplasty for posterior urethral stenosis.

ABSTRACT: Posterior urethral stenosis occurs commonly following traumatic urethral injury, treatment for prostatomegaly or prostate cancer, and pelvic radiation. Perineal reconstruction for posterior urethral stenosis can be performed via excisional urethroplasty with primary anastomosis, or via substitution urethroplasty with the use of buccal mucosa graft (BMG). This article provides a stepwise description and comprehensive review of our technique for posterior substitution urethroplasty. Helpful tips and recommendations regarding common pitfalls encountered perioperatively are also presented. Key maneuvers described include unilateral urethral mobilization, graft fixation using laparoscopic suturing devices, fibrin sealant, or a barbed-suture sewing machine, as well as the use of the RaViNi light
