[Alternative endourologic methods for treatment of urethral stricture]

Advances in endoscopic instrumentation and techniques offer new alternatives for safe and effective treatment of urethral strictures. Visual internal urethrotomy, the standard treatment modality, is associated with new scar formation with stricture recurrence. This experience has led to the investigation of alternative techniques which would avoid or ameliorate this result. This article reviews the current literature and discusses these newer approaches, including balloon dilatation, laser urethrotomy, endoscopic urethroplasty, "cut to the light" and "core through" procedures, and urethral wallstent implantation.
