This is a review of our experience with the Snodgrass technique for distal hypospadias repair and we point to lessons learned in improving results.
We reviewed all patients who underwent Snodgrass hypospadias repair for distal hypospadias over a four-year period by a single surgeon. Chart review followed by parental telephone interview was used to determine voiding function, cosmesis and complication rate.
Thirty children and three adults were identified. Age at surgery ranged from seven months to 39 years. The urinary stream was straight in 94%, and 97% reported a good or satisfactory final cosmetic outcome. One patient (3.3%) developed a urethral fistula and 21% developed meatal stenosis which required general anaesthetic.
The Snodgrass urethroplasty provides satisfactory cosmetic and functional results. High rates of meatal stenosis initially encountered have improved with modifications to technique which include modified meatoplasty and routine meatal dilatation by the parents.
本文回顾了我们采用斯诺德格拉斯技术修复远端尿道下裂的经验，并指出在改善手术效果方面所吸取的经验教训。
我们回顾了由单一外科医生在四年期间为远端尿道下裂患者实施斯诺德格拉斯尿道下裂修复术的所有病例。通过查阅病历并随后对患儿家长进行电话随访，以确定排尿功能、外观效果及并发症发生率。
共确定了30名儿童和3名成人。手术年龄从7个月至39岁不等。94%的患者尿流呈直线状，97%的患者最终外观效果良好或令人满意。1例患者（3.3%）出现尿道瘘，21%的患者出现尿道口狭窄，需在全身麻醉下处理。
斯诺德格拉斯尿道成形术可提供令人满意的外观和功能效果。通过对技术进行改进，包括改良尿道口成形术以及家长常规进行尿道口扩张，最初遇到的较高尿道口狭窄发生率已有所改善。
