I potenziali evocati pudendi, i potenziali evocati motori del muscolo bulbocavernoso e il test della tumescenza peniena notturna nella diagnosi di impotenza in pazienti con sclerosi multipla

Abstract

Pudendal evoked potentials, motor evoked potentials of the bulbocavernosus muscle to magnetic stimulation and bulbocavernosus reflex were recorded in 34 MS patients: responses were delayed in 26, 20 and 3 cases respectively. No relationship was found between neurophysiological abnormalities and the presence or severity of erectile dysfunction, showing that these tests have little diagnostic usefulness in MS patients with impotence. Nocturnal penile tumescence test was assessed in 14 cases: the test was normal in 10 patients, with no additional diagnostic help.
