阴茎背神经选择性切断术改善阴茎背神经敏感性的疗效分析

Improvement of sensitivity of dorsal nerves with dorsal neurectomy

目的:观察阴茎背神经选择性切断术改善阴茎背神经敏感性的临床疗效。方法:64例原发性早泄(PE)患者实施阴茎背神经选择性切断术,术中保留正中(12点)、两侧(3点及9点)主干神经共3支,其余全部切断。术后采用中国早泄患者性功能评价表(CIPE),阴道内射精潜伏期及国际勃起功能问卷(IIEF-5)评价PE患者的勃起功能,并进行疗效判断。结果:手术后CIPE测分较术前有明显提高、阴茎背神经敏感性均较术前有明显减弱(P<0.01);手术前后IIEF评分差别不大;显效39例(60.94%),有效18例(28.12%),无效7例(10.94%),总有效率为89.06%。结论:阴茎背神经选择性切断术改善阴茎背神经敏感性疗效确切。

Objectives： To observe clinical effects of dorsal neurectomy on the improvement of the sensitivity of Dorsal nerves. Methods： Sixty -four patients with premature ejaculation were treated by Dorsal neurectomy. Three nerve branches in the middle and both sides of the trunk nerves were reserved, and all the rest nerves were cut. China Index of Premature Ejaculation （CIPE）, and International erectile function questionnaire （IIEF -5 ） were adopted to estimate erectile function of patients after the surgery. Results： The CIPE test results showed significant increased function and decreased dorsal nerve sensitivity com- pared with the patients＇ function before surgery（ P 〈 0. 01 ） ; IIEF score didnt reveal much difference before and after surgery, with 39 cases （ 60. 94% ） significantly improved, 18 cases （ 28. 12% ） moderately improved, and 7 cases （ 10. 94% ） not improved. The overall response rate was 89. 06% （n = 64）. Conclusion： Dorsal neurectomy could significantly improve the sensitivity of Dorsal nerves.
