[Neuroandrologic considerations in impotent patients with Peyronie's disease].
To asses the neuroandrologic profile of impotent patients with Peyronie's disease. We conducted a pharmacological erection test and a study of the neuroandrologic profile of 13 impotent patients with Peyronie's disease. Eight patients hhad associated conditions and no associated disease was demonstrated in the remaining 5 patients. The neuroandrologic profile was based on bulbocavernous EMG, S2-S4 evoked potentials, somatosensorial potentials of pudendal nerve, cavernous smooth muscle electromyography (SPACE), sympathetic skin response, and cystometrogram. SPACE was altered in all the cases. In the patients with no associated disease, all other data of the neuroandrologic profile were normal. Patients with associated conditions demonstrated more alterations in all other data of the neuroandrologic profile and significant differences were observed in 7 cases. No differences in the type of alterations of SPACE were observed in 7 cases. No differences in the type of alterations of SPACE were observed between both groups. The impotence associated with Peyronie's disease could be due to an intrinsic lesion of the erectile smooth muscle.
