[Penile revascularization: report of 4 cases].

: From February to June in 1989, 4 patients consulted our ward with the complaint of impotence. After each patient's history and physical examination were taken, a series of tests were administered which included hepatic and renal function, blood sugar, cholesterol, triglyceride, testosterone, prolactin level, nocturnal penile tumescence (NPT), duplex sonography, cavernosography, and internal pudendal arteriography. The results of these tests suggested vasculogenic impotence and penile revascularization was attempted. In 2 patients the Michal-II method was used. The second patient was treated with the Virag-V method. In the fourth patient, the Michal-II method was combined with the administration of the Virag-V method. After 6 months of follow-up, objective tests such as NPT and a Duplex scanning examination showed moderate improvement in the patients who received the Virag-V method, alone or in combination with the Michal-II method. Subjectively, all the patients except the one who received just the Virag-V method, felt improvement in erection angle, penetration, and satisfaction. We conclude that penile revascularization may be a more noninvasive, physiological alternative to penile prosthesis for some cases of vasculogenic impotence.
