End-to-end anastomosis

The surgical technique of “End-to-end anastomosis” is made by transecting the urethra at the level of the stricture site, removing the scar tissue and performing a direct anastomosis between the two urethral edges. This surgical technique is one of the fist operations described in the repair of urethral strictures. Basically, there are two basic types of End-to-end anastomosis:

  • End-to-end anastomosis. Using this technique, the scar tissue involving the stricture is completely removed and the new urethral lumen is made on healthy tissue with an adequate caliber (figures 1,2).

  • End-to-end anastomosis with skin or oral mucosal graft. Using this technique, the scar tissue involving the stricture is completely removed and the new urethral lumen is made on healthy tissue with an adequate caliber over the graft (figures 3,4).

The surgical technique of End-to-end anastomosis is generally suggested in the following cases:

  • patients with traumatic bulbar urethral strictures, not more than 2 cm in length.

  • patients who had undergone previous failed surgical attempt to repair urethral strictures showing a recurrent fibrous stricture not more than 2 cm in length.
