New clinical developments in the diagnosis and treatment of male sexual dysfunction have occurred in the past several years. Much of this information has not been disseminated to the general medical public. Of particular note, a series of reliable penile prosthetic devices for the treatment of advanced erectile dysfunction is now considered to be established and valid surgical therapy. The new diagnostic techniques of nocturnal penile tumescence monitoring, penile plethysmography, penile sphygmomanometry and phalloarteriography are beginning to show that some patients with erectile impotence have arteriosclerosis of the penile arteries. These patients were formerly considered to have psychogenic or idiopathic impotence. Some of these patients with vasculogenic impotence may benefit from the new surgical technique of penile revascularization, thus obviating the need for penile prosthetic implants.A preliminary report of a small series of cases of corpus cavernosum revascularization using the microsurgical implantation of the inferior epigastric artery directly into the corpus cavernosum with prolonged systemic anticoagulation gives a cure/improvement rate of 40 percent. Better selection of patients for operation and perfection of surgical technique offer the chance for improvement in this rate of success. The proper role of corpus cavernosum revascularization in the treatment of impotence remains to be clearly defined. However, these preliminary results, coupled with several reports from Europe, are sufficiently encouraging to justify continued clinical investigation and surgical experience with penile revascularization for vasculogenic impotence.
