[Postoperative results of ligation of crura penis for impotence with corporal veno-occlusive insufficiency].

We performed ligation of the crura penis for 34 impotents with corporal veno-occlusive insufficiency without arterial insufficiency and neural dysfunction from October 1987 to April 1991. Ages ranged from 24 to 72 (52.6 +/- 12.7) years old and follow up period was from 1 to 41 (17.7 +/- 12.6) months. For six patients ligation of the crura only was performed, for 22 ligation of the crura and deep dorsal vein (DDV) as well was performed at the same time, and for 6 crural ligation was performed after ligation of DDV. These operations required less than one hour and there were no severe complications. The postoperative results at 1 month were as follows: Excellent (sufficient spontaneous erection was recovered); 18, Improved (complete erection with intracavernous papaverine injection was achieved); 13, and Failure; 3. Erectile function was maintained only in 50% of the 18 pts. graded excellent. Ninety percent of the 31 patients graded either excellent or improved could maintain erectile function after 40 months with papaverine injection. Venous surgeries could not be a primary treatment for correcting the outflow abnormalities (of the veins). So it is conceivable that failure or recurrence could occur during a long follow up period. We concluded that crural ligation was acceptable as the first line treatment for erectile dysfunction due to corporal veno-occlusive insufficiency because of its relative non-invasiveness compared to other venous surgeries.
