MONONEUROPATHY OF PUDENDAL NERVE IN ALCOH OLIC PATIENTS WITH ERECTILEDYSFUNCTION - AN ELECTROPHYSIOLOGICAL STUDY ON BULBOCAVERNOSUS-REFLEX-LATENCIES, EMG AND MOTOR-NERVE CONDUCTION-VELOCITY OF PERONEAL NERVE

Our study aims to show that there may be a different allocation as to neuronal impairment in pudendal and peroneal nerve fibres in patients with alcoholic and diabetic neuropathy. 49 patients with erectile fail ure (16 alcohol abusers, 15 type-I-dabetics, 18 type-II-diabetics), we re assessed by bulbacavernosus-reflex-latency-measurement, EMG of bulb acavernous muscle, EMG of several distal muscles of the legs and motor conduction velocity of peroneal nerve. The average of mean bulbocaver nosus-reflex-latencies in alcoholics was considerably longer than in t he diabetics, whereas the average of peroneal motor conduction velocit y was higher in the alcoholics. In the alcoholics, seven subjects (43. 8%) showed pathological bulbocavernosus-reflex-latencies in combinatio n with a normal motor nerve conduction velocity, in the diabetics this was the case only in two subjects (6,0%). Slowed conduction velocitie s on the other hand were combined to normal bulbocavernosus-reflex-lat encies only in one of the alcoholics (6.3%) but in 17 (51.7%) of the d iabetics. These results suggest, that alcoholic neuropathy in contrast to diabetic neuropathy may be able to impair pudendal nerve fibres ea rly and severely in a moment, when impaired function in lower limbs ne rves only starts to reveal.
