Dorsal Onlay Oral Mucosal Graft Urethroplasty
The dorsal onlay technique, popularized by Barbagli in 1996, places a buccal mucosal graft on the dorsal urethral surface after mobilizing the urethra from the corpus spongiosum. The graft is sutured to the tunica albuginea of the corpora cavernosa, providing a vascular backing that promotes graft take. This approach is well-suited for bulbar urethral strictures and has demonstrated durable long-term patency rates.
