This study summarizes the short-term efficacy of the one-stage tubularized urethroplasty using the free inner in proximal hypospadias.
A retrospective analysis was conducted on 42 patients with proximal hypospadias. All cases were treated with one-stage tubularized urethroplasty from January 2020 to June 2021. The postoperative complications like urethral fistula, urethral stricture, diverticulum, and split penis head were recorded.
Patients were followed up for 3 to 15 months (an average of 8.5 months). A total of 26 cases (62%) were repaired without any complication. Five patients (11.9%) developed urinary fistulas and underwent secondary repair: three cases with anastomotic fistulas and two cases of coronal fistulas. Nine patients (21.4%) had stenosis of the head segment of the penis, six (14.3%) had stenosis that was relieved by urethral dilatation combined with topical mometasone furoate 1 month after urethral catheter removal. Two patients (4.8%) had severe stenosis with secondary surgical stenosis incision, and one (2.4%) had combined urethral diverticulum in which urethral stenosis incision and diverticulectomy were performed.
Tubularized urethroplasty using the free inner bears the advantages of easy access, reduced short-term complications, low incidence of diverticula.
本研究总结了一期管状尿道成形术在近端尿道下裂中的短期疗效。
回顾性分析 2020 年 1 月至 2021 年 6 月期间 42 例近端尿道下裂患者。所有病例均采用一期管状尿道成形术治疗。记录术后并发症，如尿道瘘、尿道狭窄、憩室和阴茎头分裂。
患者随访 3 至 15 个月（平均 8.5 个月）。26 例（62%）无并发症修复。5 例（11.9%）发生尿瘘，行二期修复：吻合口瘘 3 例，冠状口瘘 2 例。9 例（21.4%）阴茎头部前段狭窄，6 例（14.3%）在拔除尿道导管后 1 个月行尿道扩张联合局部糠酸莫米松治疗后狭窄缓解。2 例（4.8%）有严重狭窄，行二期手术狭窄切开术，1 例（2.4%）合并尿道憩室，行尿道狭窄切开术和憩室切除术。
游离内层管状尿道成形术具有操作简便、短期并发症少、憩室发生率低等优点。
