Excision of the urogenital diaphragm: a method of repair of the completely obstructed membranous urethra.

A 15-year experience with 16 patients who suffered complete rupture of the membranous urethra and obliteration of the apex of the dislocated prostate gland is described. In 2 cases repair was done immediately after injury. The technique is described. Entrance into the perineum follows the path of the bulbous urethra rather than that of the rectal wall. After the bulbous urethra is mobilized the urogenital diaphragm is excised. The end of the bulbous urethra is approximated to the mobilized distal half of the prostate, via the shortest route between the 2 organs.
