阴茎勃起障碍病人神经诱发电位146例临床分析

本文对１４６例阴茎勃起障碍病人的阴部神经诱发电位（ＰｕｄｅｎｄａｌＥＰｓ）进行了检测分析，其中骨盆骨折３１例，腰椎骨折１１例，盆腔手术９例，高血压１６例，糖尿病１７例，严重手淫６２例。分析结果：阴部皮层体感神经诱发电位（ＣＰＥＰ）、骶髓反射时（ＳＲＬ）和生殖皮层运动诱发电位（ＣＭＥＰ）总体异常率在骨盆骨折、腰椎损伤、盆腔手术、高血压、糖尿病及严重手淫组分别为５１．６１％、５４．５５％、７７．７７％、３１．２５％、４７．０５和３２．２６％，超强度电流刺激在骨盆骨折、腰椎损伤、盆腔手术、高血压、糖尿病及严重手淫组依次为５５．５５％、４５．５４％、４１．１７％、３８．７０％、３０．６０％和６．２５％。研究结果表明：在骨盆骨折、腰椎损伤、盆腔手术及糖尿病人，其ＰｕｄｅｎｄａｌＥＰｓ异常率及超强度刺激率都相当高。提示在这些病人中阴部神经受损的机率较高，而ＰｕｄｅｎｄａｌＥＰｓ检测将有助于阴茎勃起障碍的病因学诊断

Analysis of the pudendal evoked potentials of 146 cases of patients with erectile dysfunction

Extensive pudendal evoked potentials evaluation were carried out in the patients with erectile dysfunction. The tests consisted of scalp somatosensory evoked potentials, scalp motor evoked potenials and sacral reflex latency. Of these patients, 31 have the erectile dysfunction after the fracture of pelvic, 11 after lumber fracture or lumber nerve damages, 9 after pelvic surgery, 16 with hypertention, 17 with diabetes and 62 with the history of severe masturbation more than 5 years. The results showed that the rate of the abnormality of the pudendal evoked potentials were 51.61%, 54.53%, 77.77%, 31.25%, 47.05% and 32.26% in the groups of the patients with pelvic fracture, lumber fracture or lumber nerve damages, pelvic surgery, hypertention, diabetes and severe masturbation respectively. The rate of extra-electricle stimulation were 55.55%, 45.54%, 41.17%, 33.70%, 30.60% and 6.25% respectively. This study indicated that the above mentioned patients have high possibility of the pudendal, sacral and spinal nerve injuries, and the pudendal evoked potentials are very useful in the diagnosis of the erectile dysfunction.
