前列腺电切术对勃起功能的影响(附64例报告)

Impact of transurethral resection of the prostate on erectile function: A report of 64 cases

目的:分析经尿道前列腺电切术(TURP)对勃起功能的影响程度及引起术后勃起功能障碍(ED)的因素。方法:对64例老年前列腺增生患者TURP术前及术后3个月进行阴茎夜间勃起功能(NPT)检测、勃起功能国际问卷(IIEF-5)、焦虑自评量表(SAS)评估。结果:术中穿破前列腺包膜者较包膜完整者ED发生率比后者高(9/15 vs 11/49,P<0.05),术后SAS评分较术前明显升高(44.01±6.21 vs 38.28±5.66,P<0.01)。IIEF-5评分术后较术前降低,其差异具有统计学意义(19.06±4.55 vs 22.56±0.54,P<0.01)。结论:术中是否穿破前列腺包膜、术后焦虑心理因素对TURP术后勃起功能障碍影响明显。

Objective： To analyze the impact of transurethral resection of the prostate （TURP） on erectile function and the fac- tors influencing postoperative erectile function. Methods ： Altogether 64 male patients aged 53 - 75 （ mean 66.5 ） years underwent TURP for prostatic hyperplasia. Before and 3 months after surgery, we observed the nocturnal penile tumescence of the patients and analyzed their scores on the 5-item version of the International Index of Erectile Function （ IIEF-5 ） and the Self-Rating Anxiety Scale （SAS）. Results： Intraoperative prostatic capsule perforation and postoperative stress were significantly related to postoperative erectile dysfunction （ P 〈 0.05 ）. The mean score of IIEF-5 was significantly decreased （ P 〈 0. 01 ） while that of SAS remarkably increased （ P 〈 0.01 ） after TURP as compared with those before surgery. The frequency of nocturnal penile tumescence was reduced at 3 months after surgery, but with no statistically significant difference. Conclusion： Intraoperative prostatic capsule perforation and postoperative stress obviously affect postoperative erectile function.
