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 influence of transurethral resection of prostate (TURP) on erectile function and the factors that cause postoperative erectile dysfunction (ED). Methods: Sixty-four elderly BPH patients underwent preoperative TURP and 3 months after operation. The penile nighttime erectile function (NPT) test, IIEF-5 and SAS were evaluated. Results: The incidence of ED was higher in patients with penetrated prostate capsule than those with intact capsule (9/15 vs 11/49, P <0.05), and postoperative SAS score was significantly higher than that before operation (44.01 ± 6.21 vs 38.28 ± 5.66, P <0.01). The score of IIEF-5 was significantly lower than that before operation (19.06 ± 4.55 vs 22.56 ± 0.54, P <0.01). Conclusion: Whether or not to perforate the prostate capsule during operation, postoperative anxiety and psychological factors have obvious effect on erectile dysfunction after TURP.
