There are four basic types of Urethroplasty with skin or oral mucosal graft:

  • Urethroplasty with ventral oral mucosal graft. Using this technique, the oral graft is sutured on the ventral site of the urethra (figures 1,2).
  • Urethroplasty with dorsal skin or oral mucosal graft. Using this technique, the oral graft is sutured on the dorsal site of the urethra (figures 3,4).
  • Urethroplasty with lateral oral mucosal graft. Using this technique, the oral graft is sutured on the lateral site of the urethra.
  • Urethroplasty with complete substitution by oral mucosal graft. Using this technique, the urethral mucosa is completely replaced by an oral graft.


The surgical technique of Urethroplasty with skin or oral mucosal graft is generally suggested in the patients with no traumatic bulbar urethral strictures, more than 2 cm in length.
