目的通过前瞻性研究明确经尿道前列腺等离子切除术对性功能的影响。方法 2008年1—12月共198例良性前列腺增生患者行经尿道前列腺等离子切除术,根据国际阴茎勃起功能指数表对术前及术后6个月时患者的阴茎勃起功能情况、性欲、射精情况及性生活质量进行对比。结果 198例患者均接受调查,其中165例资料完整且术后有性生活者入选,平均年龄为(71.2±9.8)岁。术前阴茎勃起功能指数评分为(23.4±4.7)分,与术后6个月(24.1±4.9)分的差异无统计学意义(P>0.05)。术前及术后6个月有性欲者分别占74.5%(123/165)及80.0%(132/165),手术前、后的差异无统计学意义(P>0.05);射精异常者分别占18.8%(31/165,其中逆行射精19例)及75.2%(124/165,其中逆行射精106例),手术前、后的差异有统计学意义(P<0.05);对性生活满意者分别占77.6%(128/165)及80.0%(132/165),手术前、后的差异无统计学意义(P>0.05)。结论经尿道前列腺等离子切除术对阴茎勃起功能和性欲无明显影响,术后射精功能障碍明显增多,但对性生活满意度无明显影响。
Objective To investigate the effect of transurethral resection of prostate on sexual function through prospective study. Methods A total of 198 benign prostatic hyperplasia patients underwent transurethral resection of the prostate from January to December in 2008. According to the International Penile Erectile Function Index (EAPI), the erectile dysfunction, libido and ejaculation in preoperation and postoperative 6 months were analyzed. Sexual quality comparison. Results A total of 198 patients were enrolled. Among them, 165 patients were complete and had sex after operation, with an average age of (71.2 ± 9.8) years. Preoperative penile erectile function index score was (23.4 ± 4.7) points, and 6 months after operation (24.1 ± 4.9), the difference was not statistically significant (P> 0.05). There were 74.5% (123/165) and 80.0% (132/165) of patients who had preoperative and postoperative 6 months of sexual desire, respectively, with no significant difference before and after operation (P> 0.05). The patients with abnormal ejaculation accounted for 18.8% (31/165, retrograde ejaculation in 19 cases) and 75.2% (124/165 cases, including retrograde ejaculation 106 cases), before and after surgery were statistically significant differences (P <0.05) Accounting for 77.6% (128/165) and 80.0% (132/165) respectively. There was no significant difference between before and after surgery (P> 0.05). Conclusions Transurethral resection of prostate with no effect on erectile function and libido has obvious effect on postoperative ejaculation dysfunction but no significant effect on sexual satisfaction.
