Visual internal urethrotomy (VIU) is an option for the management of urethral stricture. However, little is known regarding sexual function after surgery.
Seventy-six patients who underwent VIU were evaluated by using the Korean version of the Male Sexual Health Questionnaire. Three sexual functional domains of erection (EFD), satisfaction (SAD), and ejaculation (EjFD) were assessed at baseline, 3 months, 6 months, and 12 months after surgery. We assessed clinical factors (age, etiology, and maximum flow rate) and radiologic factors (stricture site, stricture length, frequency of recurrence, and duration until first recurrence). We compared with each sexual functional domain score by age group (range: 40-49, 50-59, 60-69, and 70-79 years).
A total of 76 men with mean age of 57.1±13.07 years completed this study. In univariate analysis, there were significant losses of EFD scores at postoperative 3 months for all age groups (P<0.05). And these scores were regained after postoperative 6 months. There was no statistically significant difference in SAD. Age, length of stricture, frequency of recurrence, and duration until first recurrence were significant differences in EjFD (P<0.001, P=0.006, P=0.005, and P=0.013, respectively). In 40 to 49 and 50 to 59 age groups, VIU improves EjFD (P<0.001, respectively). Multiple linear regression analysis revealed that age and stricture length were independent factors of VIU on EjFD (P<0.001 and P=0.013, respectively).
VIU can improve ejaculatory function in younger age group (40-59 years). Age and stricture length are independent predictive factors of VIU on ejaculatory function.
尿道内切开术（VIU）是治疗尿道狭窄的一种选择。然而，对于手术后的性功能知之甚少。
76 名接受 VIU 治疗的患者使用韩国版男性性健康问卷进行了评估。在手术前、术后 3 个月、6 个月和 12 个月，评估了勃起功能（EFD）、满意度（SAD）和射精功能（EjFD）这三个性功能领域。我们评估了临床因素（年龄、病因和最大尿流率）和影像学因素（狭窄部位、狭窄长度、复发频率和首次复发时间）。我们将每个性功能领域的评分与年龄组（40-49 岁、50-59 岁、60-69 岁和 70-79 岁）进行了比较。
共有 76 名平均年龄为 57.1±13.07 岁的男性完成了这项研究。在单因素分析中，所有年龄组术后 3 个月的 EFD 评分均显著下降（P<0.05）。这些评分在术后 6 个月后恢复。SAD 无统计学差异。年龄、狭窄长度、复发频率和首次复发时间是 EjFD 的显著差异因素（P<0.001、P=0.006、P=0.005 和 P=0.013）。在 40-49 岁和 50-59 岁年龄组，VIU 改善了 EjFD（P<0.001，分别）。多元线性回归分析显示，年龄和狭窄长度是 VIU 对 EjFD 的独立影响因素（P<0.001 和 P=0.013）。
VIU 可改善年轻年龄组（40-59 岁）的射精功能。年龄和狭窄长度是 VIU 对射精功能的独立预测因素。
