【摘要】 目的通过开展球海绵体肌反射（ＢＣＲ）。坐骨海绵体肌反射（ＩＣＲ）及阴部诱发电位（ＰＥＰ）等电生理检测，评价该技术对伴有马尾神经损伤患者的诊断价值。方法１２７例男性均经影像学和手术证实为腰椎间盘突出症及腰椎管狭窄症患者，进行ＢＣＲ、ＩＣＲ、ＰＥＰ检查。另选１０例正常受试者进行相同的检查对照。结果１２７例患者中，发现异常者５９例（４６．５％），表现为潜伏期延长或波形消失，提示这些患者已存在不同程度的马尾神经损害。而经临床诊断为马尾神经损害患者只有３９例（３０．７％），此结果明显高出临床对马尾神经损害的诊断。经χ２检验Ｐ＜０．００５。结论ＢＣＲ、ＩＣＲ、ＰＥＰ检查能灵敏地、客观地反映马尾神经的功能状态。对马尾综合征患者具有诊断价值，该检查对手术疗效和预测预后也提供了有效的客观指标。更多还原

【Abstract】 Objective To evaluate the clinical value of the electrophysiological tests of bulbocay-ernosus refiex (BCR) , ischiocavernosus reflex (ICR) and pudenda evoked potential (PEP) in diagnosis ofcauda equina injury. Methods BCR, ICR and PEP were perfomied in 127 males with lumbar disc pro-trusion and lumbar spinal stenosis. The results were compared with 10 norinal controls. Results 59 of127 (46. 5%) patients had abnornial data, which were more sensitive than clinical findings. BCR, ICR andPEP were either absent or presented with a profonged latency. Conclusion BCR, ICR and PEP wereable to objectively and sensitively reflect the functions of the cauda equina. Therefore, BCR, ICR and PEP were reliable methods for the diagnosis of cauda equina syndrome, and were useful in evaluation of the efficacy of surgical procedure and in prediction of the prognosis.更多还原
