Surgical treatment of impotence due to venous outflow.

Coital impotence was studied in 94 patients. In 14 of them the history, as well as the papaverine-induced erection, penile Doppler test and dynamic cavernosography suggested venous outflow as a basic process. In 13 who underwent surgery, the draining vein visualized by dynamic cavernosography was tied down. Seven patients now have spontaneous erection, four present it upon intravenous papaverine injection. Two operations failed: one for an existent spongiocavernous fistula, the other for the development of collateral circulation in the early phase.
