Successful use of the Snodgrass modification of Tiersch-Duplay urethroplasty for repair of distal hypospadias has been reported. Given the features of the repair: technical simplicity, preservation of the urethral plate, single suture line in the urethroplasty and no need for vascularized pedicle graft, we felt that the technique could be applied to the treatment of proximal hypospadias.
A retrospective review of the records of 35 patients with either midshaft or penoscrotal hypospadias who underwent a Snodgrass type of hypospadias repair was carried out. Age at surgery was 3 to 54 months (mean age: 8.4 months). No patients with significant chordee were included. All patients had indwelling urethral stents for 5 to 7 days postoperatively. Follow-up ranged from 6 months to 3 years.
There were no immediate postoperative complications. Four patients experienced a urethrocutaneous fistula in association with meatal stenosis. After meatal dilatation, 2 of these fistulae closed spontaneously for an overall fistula rate of 5.7%. The overall cosmetic result of the glans and urethral meatus was noted to be excellent. Urinary stream was normal in all cases.
Our results indicate that the Snodgrass modification of Tiersch-Duplay hypospadias repair provides satisfactory cosmetic and functional results in the treatment of proximal hypospadias with a low surgical complication rate. In young patients, it is our procedure of choice for penile and penoscrotal hypospadias without major degrees of chordee.
已有报道成功运用蒂尔施 - 杜普莱尿道下裂修复术的斯诺德格拉斯改良术式修复远端尿道下裂。鉴于该修复术的特点:技术操作简单、保留尿道板、尿道成形术中仅有一条缝合线且无需带血管蒂移植物,我们认为该技术可应用于近端尿道下裂的治疗。
对35例接受斯诺德格拉斯式尿道下裂修复术的阴茎体部或阴茎阴囊型尿道下裂患者的病历进行回顾性分析。手术年龄为3至54个月(平均年龄:8.4个月)。未纳入有明显阴茎下弯的患者。所有患者术后均留置尿道支架5至7天。随访时间为6个月至3年。
术后无即刻并发症。4例患者出现尿道皮肤瘘合并尿道口狭窄。经尿道口扩张后,其中2例瘘口自行闭合,总体瘘管发生率为5.7%。阴茎头和尿道口的整体外观效果良好。所有病例尿流均正常。
我们的结果表明,蒂尔施 - 杜普莱尿道下裂修复术的斯诺德格拉斯改良术式在治疗近端尿道下裂时能提供令人满意的外观和功能效果,手术并发症发生率低。对于年轻患者,对于无严重阴茎下弯的阴茎型和阴茎阴囊型尿道下裂,这是我们的首选术式。
