目的探讨尿道板纵切卷管尿道成形术(Snodgrass法)对治疗失败尿道下裂的临床疗效。方法回顾性分析广州军区总医院泌尿外科2002年3月-2011年4月接受Snodgrass法治疗的81例阴茎皮肤少的治疗失败尿道下裂患者的临床资料,并与36例同期应用Duplay尿道成形术修复的阴茎皮肤相对充裕的治疗失败尿道下裂患者进行比较。2种治疗方法均留置尿道U形支架管,U形支架管两端分别从会阴部尿道及尿道外口引出,均采用肉膜瓣覆盖成形尿道。结果随访6个月～2 a,应用Snodgrass手术治疗81例,成功65例(80.2%),术后并尿道瘘11例,尿道狭窄5例。Duplay尿道成形术治疗36例,成功29例(80.6%),术后并尿道瘘5例,尿道狭窄2例。2组手术成功率比较差异无统计学意义(P>0.05)。结论 Snodgrass手术用于儿童阴茎皮肤少的治疗失败尿道下裂的修复,可取得满意效果。
Objective To investigate the clinical effect of urethral plaque urethroplasty (Snodgrass) on the treatment of failed hypospadias. Methods The clinical data of 81 patients with hypospadias treated by Snodgrass method from March 2002 to April 2011 were retrospectively analyzed. The clinical data of 36 cases with hypospadias treated by Dupla urethroplasty The repair of penis skin relatively plentiful treatment failed hypospadias patients were compared. Urethra U-shaped stents were placed in the two kinds of treatment methods. Both ends of the U-shaped stents were led out from the perineal urethra and urethral orifice, respectively. Results The follow-up ranged from 6 months to 2 years. 81 cases were treated with Snodgrass operation, 65 cases were successful (80.2%). There were 11 cases of urethral fistula and 5 cases of urethral stricture. Dupla urethroplasty in 36 cases, the success of 29 cases (80.6%), postoperative urethral fistula in 5 cases, urethral stricture in 2 cases. There was no significant difference in the success rate of operation between the two groups (P> 0.05). Conclusion Snodgrass surgery for the treatment of children with small penis skin hypospadias repair failure can be satisfactory.
