n. surgical repair of the urethra, especially a urethral stricture. The operation entails the insertion of a flap or patch of skin from the scrotum or perineum into the urethra at the site of the stricture, which is laid widely open. The operation can be performed in one stage, although two stages are usual in the reconstruction of a posterior urethral stricture (see urethrostomy). Transpubic urethroplasty is performed to repair a ruptured posterior urethra following a fractured pelvis. Access to the damaged urethra is achieved by partial removal of the pubic bone.
