Abstract

Objective: To assess the efficacy of local volume reduction of the dorsal glans groove in hypospadias repair with small glans.

Methods: This retrospective comparative study included 107 children treated between January 2017 and December 2020. Patients were divided into two groups: Group 1 (2017-2018) underwent onlay island flap urethroplasty alone, while Group 2 (2019-2020) underwent the procedure with additional local volume reduction of the dorsal glans groove. Hypospadias objective scoring evaluation (HOSE) scores and postoperative complications, including glans dehiscence, meatal stenosis, and urethrocutaneous fistula, were compared.

Results: The mean follow-up was 40 months (Group 1) and 32 months (Group 2). Urethrocutaneous fistula rates were 4% (Group 1) and 2% (Group 2; P = 1). Glans dehiscence occurred in 16% (Group 1) and 4% (Group 2; P = 0.0451). Meatal stenosis rates were 16% (Group 1) and 2% (Group 2; P = 0.0184). Overall success rates were 65% (Group 1) and 92% (Group 2; P = 0.0008). HOSE scores showed no significant difference (P = 0.219).

Conclusions: Local volume reduction of the dorsal glans groove significantly reduces postoperative complications in hypospadias repair with small glans.

局部缩小龟头背沟体积在小龟头尿道下裂修复中的应用：回顾性研究。

目的：探讨小龟头修复尿道下裂时局部缩小龟头背沟的效果。方法：本回顾性比较研究纳入了2017年1月至2020年12月期间接受治疗的107例儿童。患者分为两组：组1（2017-2018）单独行岛状皮瓣尿道成形术，组2（2019-2020）行背龟头沟局部体积缩小手术。比较尿道下裂客观评分评估（HOSE）评分和术后并发症，包括龟头开裂、金属狭窄和尿道瘘。结果：平均随访时间为40个月（第一组）和32个月（第二组）。尿道瘘发生率分别为4%（第一组）和2%（第二组）；p = 1)。龟头开裂发生率分别为16%（组1）和4%（组2）；p = 0.0451)。椎管狭窄率分别为16%（1组）和2%（2组）；p = 0.0184)。总成功率分别为65%（第一组）和92%（第二组）；p = 0.0008)。HOSE评分差异无统计学意义（P = 0.219）。结论：局部缩小龟头背沟的体积可显著减少小龟头修复尿道下裂的术后并发症。
