Abstract:
OBJECTIVETo assess the clinical significance of electrophysiological tests of bulbocavernosus reflex (BCR), ischiocavernosus reflex (ICR) and pudenda somatosensory evoked potential (PSEP) for patients with erectile dysfunction (ED).
METHODSElectrophysiological tests of BCR, ICR and PSEP were performed for 232 ED patients with IIEF-5 scores of 2-20 (10.39 +/- 5.52), another 21 normal volunteer controls underwent the same tests, and the results were compared.
RESULTSAbnormal results, such as prolonged and advanced latencies, were found in 94 (40.5%) of the patients, which suggested neurotic ED with different degrees of cauda equine nerve injuries.
CONCLUSIONElectrophysiological tests of BCR, ICR and PSEP can objectively reveal the functional state of the cauda equine nerve and offer an important support to the diagnosis of nerve-mediated ED.
