目的 :探讨经尿道前列腺电气化术 (TV P)中出现闭孔神经和阴茎勃起反射的有关问题。方法 :采用TVP治疗前列腺增生症 (BPH ) 15 6例。结果 :术中分别出现闭孔神经反射和阴茎勃起反射 8例 (5 .1% )和 7例(4 .5 % ) ,均发生于气化电极接近神经分支和气化电流较强时。结论 :高频电流中混有低频电流是引起术中神经反射的主要原因 ,气化电流的大小决定此类反射发生与否 Objective: To investigate the related problems of obturator nerve and penile erection reflex in transurethral electrovaporization (TVP). Methods: TVP treatment of benign prostatic hyperplasia (BPH) 15 6 cases. RESULTS: Occult and penile erection occurred in 8 cases (5.1%) and 7 cases (4.5%), both of which occurred when the gasification electrode was close to the nerve branch and the gasification current was strong. Conclusion: The high-frequency current mixed with low-frequency current is the main cause of intraoperative nerve reflex, the size of the gasification current determines the occurrence of such reflexes or not
