Ventral Onlay Oral Mucosal Graft Urethroplasty

Ventral onlay urethroplasty places the oral mucosal graft on the ventral urethral surface, taking advantage of the rich vascular supply of the corpus spongiosum to nourish the graft. The technique avoids urethral mobilization, theoretically preserving periurethral vascularity and innervation. It is commonly used for mid-to-distal bulbar strictures where spongiosal thickness is adequate to support graft incorporation.
