Abstract
A total of 11 men (mean age 51.4 years, 1-year followup) with venous leakage impotence underwent surgical venous ligation. Of the men 8 had erections twice per week immediately after the procedure but at 3 months only 2 remained potent. Dynamic pharmacological cavernosography and cavernosometry were repeated 3 months postoperatively and 6 of the 11 men had venous leakage. These men with venous leakage underwent percutaneous embolization with platinum coils and 4 had successful results. Three additional men became potent after embolization. Of the 11 men 9 are documented to have normal dynamic cavernosography and cavernosometry findings after the combination of an operation and embolization, and 5 are potent. The postoperative and post-embolization dynamic cavernosometry data show that all 11 men have a marked decrease in the flow to maintain erection. Eight men have erections with papaverine or prostaglandin E1 intracorporeal injections. Postoperative dynamic cavernosography and cavernosometry can be diagnostic as well as therapeutic with embolization.
