Abstract
Of 62 hospitalized patients with Peyronie''s disease 18 (29%) had abnormal nocturnal penile tumescence studies that were characterized as indicating organic impotence. The majority of these patients had some underlying disease or factor other than the plaque itself to explain the altered nocturnal penile tumescence. In only 5% of these patients could the abnormal nocturnal penile tumescence be attributable to the plaque itself. Primary excision of the plaque and dermal grafting improved erectile function in all except a minority of patients who required insertion of a penile prosthesis to alleviate continued erectile impotence. For this reason insertion of a penile prosthesis during plaque excision is not recommended. The plaque of Peyronie''s disease does not appear to impede vascular flow distal to the plaque. Previous excision may result in altered hemodynamics that can result in erectile impotence.
