486例原发性早泄患者龟头敏感神经检测结果分析

Analysis of penile nerve detection in 486 cases with premature ejaculation

目的:探讨原发性早泄(PE)患者龟头敏感神经检测结果,以及龟头敏感神经检测对诊断原发性早泄的临床意义。方法:收集486例原发性早泄患者作为观察组,另选156例性功能正常男性作为对照组,分别采用Sensiometer数字震动感觉阈值(VPT)检查仪检测龟头3点、6点、9点和12点方向,并统计分析。结果:观察组中分年龄段比较VPT结果,年龄小于30岁共236人,记为组1;大于或等于30岁、小于40岁共153人,记为组2;年龄大于或等于40岁共97人,记为组3。组1中3、6、12点与组2比较有统计学差异(P<0.05),组1中9点与组2比较无统计学差异(P>0.05);组1中3、6、9、12点与组3比较均有统计学差异(P<0.05);组2中3、6、9、12点与组3比较亦有统计学差异(P<0.05)。观察组和对照组四位点VPT检测结果比较,均有显著性统计学差异(P<0.01)。结论:随着年龄的增长,原发性PE患者VPT检测的各点数值有逐渐增大趋势,龟头敏感度有不同程度减低。VPT检测可考虑作为PE诊断筛选的一种方法。

Objectives： To analyze and discuss penile nerve detection result of patients with premature ejac- ulation （PE） as well as clinical significance of penile nerve detection for the diagnosis of PE. Methods： 486 patients with PE were selected as observation group; 156 males with normal sexual function were selected as control group. The 3- o＇ clock, 6- o＇ clock, 9 -o＇ clock and 12 -o＇clock position of glans penis were tested by using VPT inspection tester. Statistical analysis of detection results was conducted. Results： In the observation group, ac- cording to different ages, 236 patients younger than 30 years old was selected as Group 1 ; 153 patients older than or equal to 30 years old or younger than 40 years old was as Group 2 ; 97 patients older than or equal to 40 years old as Group 3. The 3 -o＇ clock, 6 - o＇ clock and 12 - o＇ clock position in Group 1 and those in Group 2 had significantly statistical differences （ P 〈 0. 05 ）. The 9 - o＇ clock position in Group 1 and that in Group 2 had no significantly sta- tistical difference （P 〉 0. 05）. The 3 - o＇ clock, 6 - o＇ clock, 9 - o＇ clock and 12 - o＇ clock position in Group 1 and those in Group 3 had significantly statistical differences （ P 〈 0.05 ）. The 3 - o＇ clock, 6 - o＇ clock, 9 - o＇ clock and 12 - o＇ clock position in Group 2 and those in Group 3 had significantly statistical differences （ P 〈 0. 05 ）. Significantly statistical differences in the VPT detection results were found in 3 - o＇ clock, 6 - o＇ clock, 9 - o＇ clock and 12-o＇ clock position between observation group and control group （P 〈 0. 01 ）. Conclusions： With the growth of age, VPT detection values at different positions of patients with PE have gradually increasing trend, and the penis sensitivity has different degrees of reduction. VPT test can be taken as a method of PE diagnosis and screening.
