[Clinical significance of electrophysiological tests of BCR, ICR and PSEP for ED patients].

Objective:To 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).Methods:Electrophysiological 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.Results:Abnormal 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.Conclusion:Electrophysiological 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.Natl J Androl,2008,14(12):1115-1117
