[The Evaluation, Classification and Management of 300 Impotent Patients].

Three hundred impotent patients were evaluated by a general and sexual questionnaire, clinical examination, hormonal assay, penile blood pressure measurements, erectiometry, urodynamic studies and ultrasonography of the corpus cavernosum. The patients were classified according to the cause of the impotence; 44% had a psychogenic basis, 13% a neuropathy, 39% a vasculogenic cause and 4% a combination of neuropathy and angiopathy. Psychogenically impotent patients were referred for further treatment. Twenty penile prostheses were implanted in the organic group; 19 patients were satisfied with the result. This diagnostic approach to impotence classification and treatment according to the cause and the careful selection of patients for surgery improved the success rate.
