To examine the impact on sexual function of treatments for lower urinary tract symptoms in men.
Multicentre pragmatic randomised controlled trial of standard surgery (transurethral resection of the prostate), non-contact laser therapy, and conservative management (no active intervention).
Three clinical centres in the United Kingdom.
340 men aged between 48 and 90 years with lower urinary tract symptoms related to benign prostatic enlargement.
ICSsex questionnaire items concerned with erectile stiffness, ejaculatory volume, pain or discomfort on ejaculation, whether sex life was spoilt by urinary symptoms.
Erectile and ejaculatory dysfunction were common (70%) and problematic at baseline and showed the expected trends with ageing. After treatment, reduced ejaculation was reported in all groups but was not significantly worse after standard surgery than after laser therapy. Erectile function was significantly improved after standard surgery; no significant difference was found between standard surgery and laser therapy (odds ratio 0.70, 95% confidence interval 0.36 to 1.38). Standard surgery was significantly better at relieving pain or discomfort on ejaculation than either conservative management (0.06, 0.007 to 0.49) or laser therapy (0.09, 0.01 to 0.73).
Compared with laser therapy standard surgery for lower urinary tract symptoms has a beneficial effect on aspects of sexual function-particularly in improving erectile function and reducing reported pain or discomfort on ejaculation. Older men who need treatment and want to retain or improve sexual function may thus want to consider standard surgery rather than non-contact laser therapy.
研究男性下尿路症状治疗方法对性功能的影响。
对标准手术(经尿道前列腺切除术)、非接触激光治疗和保守治疗(无积极干预)进行多中心实用随机对照试验。
英国的三个临床中心。
340名年龄在48至90岁之间、患有与良性前列腺增生相关的下尿路症状的男性。
国际尿控学会性问卷中有关勃起硬度、射精量、射精时的疼痛或不适、性生活是否因尿路症状而受影响的项目。
勃起功能障碍和射精功能障碍很常见(70%),且在基线时就存在问题,并呈现出随年龄增长的预期趋势。治疗后,所有组均报告射精减少,但标准手术后的射精减少情况并不比激光治疗后更严重。标准手术后勃起功能显著改善;标准手术与激光治疗之间未发现显著差异(优势比0.70,95%置信区间0.36至1.38)。标准手术在缓解射精时的疼痛或不适方面明显优于保守治疗(0.06,0.007至0.49)或激光治疗(0.09,0.01至0.73)。
与激光治疗相比,下尿路症状的标准手术对性功能的某些方面有有益影响,特别是在改善勃起功能和减轻报告的射精时疼痛或不适方面。因此,需要治疗且希望保留或改善性功能的老年男性可能会考虑标准手术而非非接触激光治疗。
