Risk factors of postoperative sexual function in patients with urethral diverticulum and their partners: A cohort study of 83 women

ABSTRACT Introduction and Objective: Several studies have focused on the treatment and recurrence of urethral diverticulum (UD). However, few investigations have addressed sexual function in patients with UD. Therefore, we sought to examine sexual function in women affected by UD. Materials and Methods: There were 108 accepted cases involving transvaginal diverticulectomy at our institution. Ultimately, 83 women were included for further analysis, only 61 of these women had sexual partners. We collected data for the Female Sexual Function Index (FSFI) from the female patients and the Male Sexual Health Questionnaire (MSHQ) from their male partners before and after surgery. Results: Preoperatively, the UD size affected the female patient's arousal and lubrication (p=0.04), and the UD location affected their satisfaction. However, no significant between-group differences were found in the total FSFI score. For all women, sexual activity improved after surgery (p=0.0087). In addition to improvements in arousal for women with a large UD, improvements in lubrication were affected by the UD size, number and shape, increases in satisfaction scores were impacted by the UD location and shape, and pain relief was linked to the UD number and shape. Analysis of the MSHQ results revealed no between-group differences among the male partners. Conclusion: Only the UD size and location affected sexual function in women with a small UD. Surgery could improve female sexual function but did not affect the sexual function of the patient's partners.

摘要
引言与研究目的：多项研究已围绕尿道憩室（urethral diverticulum, UD）的治疗与复发展开，但鲜有研究关注尿道憩室患者的性功能状况。因此本研究旨在探讨罹患尿道憩室的女性患者的性功能水平。
材料与方法：本机构共收治108例接受经阴道憩室切除术的病例，最终纳入83例女性患者进行后续分析，其中仅61例拥有性伴侣。我们分别于术前及术后收集女性患者的女性性功能指数（Female Sexual Function Index, FSFI）数据，以及其男性伴侣的男性性功能健康问卷（Male Sexual Health Questionnaire, MSHQ）数据。
结果：术前，尿道憩室体积会影响女性患者的性唤起与润滑状态（p=0.04），憩室位置则对其性满意度存在影响，但各组间的女性性功能指数总评分未呈现显著差异。所有女性患者的性生活质量均在术后得到改善（p=0.0087）。对于憩室体积较大的女性患者，其性唤起症状得到改善之外，润滑状态的改善与憩室体积、数量及形态相关；性满意度评分的提升则受憩室位置与形态影响；而疼痛缓解程度与憩室数量及形态存在关联。对男性伴侣的男性性功能健康问卷结果分析显示，各组间无显著差异。
结论：仅憩室体积与位置会对小型尿道憩室女性患者的性功能产生影响。手术可改善女性患者的性功能，但不会对其伴侣的性功能造成影响。
