摘要
目的通过阴茎生物震感阈值测定法评估阴茎背神经选择性切断术前后阴茎敏感度的变化。方法原发性早泄患者92例行阴茎背神经选择性切断术,分别检测术前、术后1个月和术后3个月的阴茎生物震感阈值。结果阴茎头震感阈值(GPVT):术前为(0.048±0.015)μm,术后1个月为(0.280±0.084)μm,术后3个月为(0.282±0.081)μm;阴茎体震感阈值(PSVT):术前为(0.061±0.014)μm,术后1个月为(0.064±0.022)μm,术后3个月为(0.065±0.020)μm。统计学方差分析:(1)术后1个月GPVT比术前明显升高(P<0.05);(2)术后3个月GPVT比术前显著升高(P<0.05);(3)术后1个月和3个月GPVT无明显变化(P>0.05);(4)术前、术后PSVT无明显变化(P>0.05)。结论(1)阴茎生物震感阈值测定法是简便、无创、可定量、重复性好的阴茎背神经感觉客观检测方法之一。(2)阴茎背神经选择性切断术后阴茎头敏感度降低、震感阈值提高。(3)阴茎背神经选择性切断术治疗原发性早泄安全、有效。
Objective To study the effect of dorsal penile nerve selective neurectomy on the sensitivity of the penile before and after surgery. Methods The penile vibration thresholds of penils in 92 cases of patients with primary premature ejaculation who underwent the dorsal penile nerve selective neurectomy were detected before operation and a a month and 3 months fter operation. Results The glans penis vibration thresholds （GPVT） was （0.048±0.015） μm before operation, （ 0.280± 0.084） μm 1 month after operation, （0.282±0.081）μm 3 months after operation; The penile shaft vibration thresholds （PSVT） was （0.061±0.014）μm before operation, （0.064±0.022） μm 1 month after operation, （0.065±0.020） μm 3 months after operation.Statistical analysis showed： （1）GPVT at a month after operation significantly higher than that before operation（P〈0.05）. （2）GPVT at 3 months after operation was significantly higher than before operation （P 〈0, 05）. （3）Between one month after.operation and 3 months after operation non significant change was found in GPVT（P〉 0.05）. （4）No significant change was found in PSVT preoperative and postoperative （P〉 0.05）. Conclusion 1, Detection of penile vibration thresholds is simple, noninvasive, quantitative, reproducible methods for dorsal penile nerve sensitivity of objective testing methods. 2, After dorsal penile nerve selective neurectomy ,the sensitivity of the glans penis decreased and the threshold level become higher. 3, Dorsal penile nerve selective neurectomy is safe and effective for the treatment of primary premature ejaculation.
