目的:总结Snodgrass和Duckett两种尿道成形术治疗中间位、后位尿道下裂的经验与体会。方法:对2008年1月~2012年12月接受Snodgrass和Duckett尿道成形术治疗的261例中间位及后位尿道下裂患者情况进行回顾性分析。结果:Snodgrass术与Duckett术尿道瘘的发生率分别为11.9%(15/126)和8.1%(11/135),尿道狭窄发生率分别为4.8%(6/126)和5.9%(8/135),差异无统计学意义(均P>0.05);中间位与后位尿道下裂尿道瘘的发生率分别为7.0%(10/142)和13.4%(16/119),尿道狭窄的发生率分别为3.5%(5/142)和7.6%(9/119),差异有统计学意义(均P>0.05);后位尿道下裂并发症的发生率高于中间位尿道下裂。结论:对阴茎头发育较好,尿道板发育良好,中、轻度阴茎下弯者,采用Snodgrass术是理想的手术选择。对背侧包皮发育良好,阴茎下弯明显需横断尿道板者,采用Duckett术是一种较好的手术选择。
OBJECTIVE: To summarize the experiences and experiences of Snodgrass and Duckett in the treatment of medial and posterior hypospadias. Methods: A retrospective analysis of 261 medically and posteriorly hypospadias patients undergoing Snodgrass and Duckett urethroplasty between January 2008 and December 2012 was performed. Results: The incidence of urethral fistulas was 11.9% (15/126) and 8.1% (11/135) for Snodgrass and Duckett respectively. The incidence of urethral stricture was 4.8% (6/126) and 5.9% (8/135), respectively ), The difference was not statistically significant (all P> 0.05); the median and posterior urethral fistula rates were 7.0% (10/142) and 13.4% (16/119), the incidence of urethral stricture (3.5% (5/142) and 7.6% (9/119) respectively), the difference was statistically significant (all P> 0.05). The incidence of posterior hypospadias complication was higher than that of median hypospadias. Conclusion: Good development of the penis, urethral plate well developed, moderate and mild penile bending, the use of Snodgrass surgery is the ideal choice. On the dorsal foreskin well-developed, penile bends need to transection urethra plate obviously, the use of Duckett surgery is a better surgical choice.
