We treated seventy venogenic impotents with ligation of the deep dorsal vein of the penis. Their corporal veno-occlusive function was evaluated by dynamic infusion cavernosometry and cavernosography (DICC). Under local anesthesia, we made a longitudinal skin incision at the base of the penis. The deep dorsal vein was ligated and also a portion of this vein of 1. 5 cm long was resected together with branches surrounding the vein.

As four years after the treatment only thirty percent of those who had achieved the initial erectile capability still remained potent. This operation is easy to perform without any major complications, and its outcome is as good as that achieved by other more invasive venous ligation in the treatment of patients with venogenic impotence. We therefore conclude that penile deep dorsal vein ligation and partial resection of the vein one of the most useful treatments currently available for venogenic impotence and should be the treatment of choice.
