摘　　要：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 。Purpose:To evaluate the possible mechanism of nervi obturatorius reflex and penis erection reflex appeared in the operation of electrovaporization of the prostate (TVP) and investigate the preventive measures against the reflexes.Methods:The clinical data of 156 cases of benign prostatic hyperplasia (BPH) treated with TVP were summarized.Results:Nervi obturatorius reflex and penis erection reflex appeared in 8 ( 5.1 %) and 7 ( 4.5 %) patients respectively.These reflexes were all appeared when the electrovaporization probe was near the branch of the nervi and the electrovaporization electricity was higher.Conclusions:The main reason of the appearence of the reflexes is lower frequence electricity mixed into high frequence one.The power of the electrovaporization electricity determines the appearence of the reflexes.More attention must be paid to the reflexes in order to avoid perforation of bladder wall or prostate capsule.
