目的探讨横裁带蒂包皮岛状皮管尿道成形术(Snodgrass术)与尿道板纵切卷管尿道成形术(Duckett术)治疗尿道下裂的疗效和适应证。方法回顾性分析831例尿道下裂患儿的临床资料,比较Snodgrass术式(436例)与Duckett术式(395例)进行治疗的手术成功率及其并发症。结果患儿均获得随访,随访2～36个月。采用Snodgrass术一次手术成功395例,成功率90.6%(395/436);术后发生并发症41例(9.4%)。Duckett术一次手术成功330例,成功率83.5%(330/395);术后发生并发症65例(16.5%)。结论 Duckett与Snodgrass是治疗尿道下裂常用的术式,且效果满意,临床术式的选择应根据患儿阴茎下弯程度、尿道缺损情况及术者对术式理解掌握水平决定。
Objective To investigate the curative effect and indications of transcutaneous bandaged island preputial island urethroplasty (Snodgrass) and urethral plaque (ureteroplasty) in treating hypospadias. Methods The clinical data of 831 children with hypospadias were retrospectively analyzed. The operative success rates and complications of Snodgrass operation (436 cases) and Duckett operation (395 cases) were compared. Results All patients were followed up for 2 ~ 36 months. A total of 395 cases were successfully treated with Snodgrass, with a success rate of 90.6% (395/436). Postoperative complications occurred in 41 cases (9.4%). Duckett operation was successful in 330 cases, the success rate was 83.5% (330/395); postoperative complications occurred in 65 cases (16.5%). Conclusion Duckett and Snodgrass are commonly used in the treatment of hypospadias, and the results are satisfactory. The choice of clinical operation should be based on the degree of penile curvature, urethral defect, and the surgeon’s understanding of the surgical procedure.
