OBJECTIVE
The aim of this study was to compare the results of the tubularized incised plate (the Snodgrass technique) and tubularized urethral plate (the Duplay technique) in distal hypospadias repair.
MATERIAL AND METHODS
Between April 2000 and September 2008, 245 distal hypospadias was corrected by a single surgeon: 132 patients underwent repair by tubularized incised plate and 113 by tubularized urethral plate. The age of the patients ranged from 16 to 48 months (mean 27 months).
RESULTS
Mean follow-up was 84 months (21-120 months). With the tubularized incised plate, the meatus was vertically oriented and expanded to the apex of the glans, and the rate of fistulae formation was low (3%) but that of neourethral stenosis was high (22%). The Duplay technique led to fistulae in nine patients (8%) and stenoses in only eight (7%).
CONCLUSIONS
The tubularized incised plate gave an excellent cosmetic result with fewer fistulae; however, more stenoses occurred than with the tubularized urethral plate technique.
目的
本研究旨在比较管状切开板法（Snodgrass技术）和管状尿道板法（Duplay技术）修复远端尿道下裂的效果。
材料与方法
2000年4月至2008年9月期间，由同一位外科医生矫正245例远端尿道下裂：132例患者采用管状切开板法修复，113例采用管状尿道板法修复。患者年龄为16至48个月（平均27个月）。
结果
平均随访84个月（21 - 120个月）。采用管状切开板法时，尿道口呈垂直方向并延伸至龟头顶端，瘘管形成率低（3%），但新尿道狭窄率高（22%）。Duplay技术导致9例患者出现瘘管（8%），仅8例出现狭窄（7%）。
结论
管状切开板法美容效果极佳且瘘管较少；然而，与管状尿道板技术相比，出现的狭窄更多。
