目的:评价尿道板纵切卷管尿道成形术(Snodgrass术)治疗尿道下裂的疗效。方法:回顾性分析2005年1月～2008年12月间31例行改良Snodgrass术的尿道下裂患者临床资料:患者年龄2～18岁,平均7.2岁,其中阴茎头型尿道下裂11例,阴茎体型尿道下裂18例,阴囊型尿道下裂2例。结果:一次手术治愈29例(93.55%);1例(3.22%)发生尿道狭窄,经尿道扩张治愈;1例(3.22%)发生尿瘘,术后6个月再次行改良Snodgrass术治愈。结论:改良Snodgrass术保留了尿道板,操作简单,手术时间短,并发症较少,手术成形效果好,对于首次手术失败后再次尿道成形效果良好,是适用于各型尿道下裂治疗的较好方法。
Objective: To evaluate the efficacy of urethral plaque urethroplasty (Snodgrass) in the treatment of hypospadias. Methods: The clinical data of 31 patients with hypospadias treated with modified Snodgrass from January 2005 to December 2008 were retrospectively analyzed. The patients were aged from 2 to 18 years (average, 7.2 years), of which 11 had hypospadias, Penis type hypospadias in 18 cases, 2 cases of scrotal hypospadias. Results: One operation was cured in 29 cases (93.55%). One case (3.22%) had urethral stricture and was cured by urethral dilatation. One case (3.22%) developed fistula and was cured by modified Snodgrass again 6 months after operation. Conclusion: The improved Snodgrass technique retains the urethral plate and has the advantages of simple operation, short operation time, less complications, good operation and good reformation, good re-urethral forming after the first operation failure, and is suitable for all kinds of hypospadias treatment method.
