RESUMO
PURPOSE: We now know that outflow restriction is essential for maintaining a rigid erection, which can be achieved after satisfactory smooth muscle relaxation. The aim of this study was to assess retrospectively the efficacy of penile vein surgical ligation in patients with a follow-up of at least 3 years. MATERIALS AND METHODS: Thirty-two men with impotence due to cavernovenous occlusive disease underwent penile vein ligation for management of organic erectile dysfunction. Cavernovenous occlusive disease was diagnosed by gravity cavernosometry. RESULTS: Long-term evaluation revealed sustained potency without adjunctive therapy in only 7 patients (21.87%). Twenty-five patients (78.12%) did not show any improvement in the erectile mechanism. Associated complications included penile shortening in 4 (12.5%), hypoesthesia of the glans area in 2 (6.25%), and Peyronie's disease in 1 (3.2%). CONCLUSION: Based on these data, we conclude that the long-term success of penile vein ligation is poor.
