The requirements of hypospadias surgery today not only include the creation of a straight phallus with optimal meatal placement but also call for excellent cosmetic outcomes with minimal complications. Specialty fellowship training as well as advanced surgical materials and techniques allow for consistent, successful results. We report the outcomes of hypospadias surgeries performed by two academic Pediatric Urologists in the first 3 years of practice after completing a 2-year fellowship.
A retrospective chart review of all patients with hypospadias treated by two surgeons (DF and JC) between July 2004 and August 2007 was performed. The two surgeons had completed a 2-year Pediatric Urology fellowship at two different institutions (Johns Hopkins and Texas Children's Hospital). Level of hypospadias, patient age, type of repair and follow up as well as complications were recorded. Midshaft and distal hypospadias were classified as distal.
In all, 187 patients were operated on. No significant difference in numbers and complications occurred between the two surgeons. Distal hypospadias was found in 149, proximal in 29, and penoscrotal or perineal was found requiring a two-stage repair in nine patients. Distal hypospadias was repaired using either dorsal plate incision with tubularization (TIP) (n=112) or meatal advancement and glanuloplasty (MAGPI) (n=37). All proximal lesions were repaired using TIP. All patients were seen after 1-2 weeks, and 6 and 12 months postoperatively. Fistulae occurred in 10 patients (three in distal, four in proximal, and three in two-stage repairs) for an overall fistula rate of 5.3%. Meatal obstruction occurred in three distal repairs and one two-stage repair, diverticulum in one proximal. No complications occurred with MAGPI repairs. All complications, except for one, were successfully repaired in a single operation.
Modern hypospadias surgical techniques pioneered through decades of surgical innovation can now be successfully transferred to the new generation of specialty-trained Pediatric Urologists. Modern pediatric fellowship training allows performing distal hypospadias repair with a minimal fistula rate of 2.8%. Proximal hypospadias remain more challenging with complication rates of 13.8% for one-stage and 33.3% for two-stage repairs.
如今尿道下裂手术的要求不仅包括打造笔直的阴茎并使尿道口位置最佳,还需要实现极佳的美容效果且并发症最少。专科进修培训以及先进的手术材料和技术能带来持续、成功的手术结果。我们报告了两位小儿泌尿外科专科医生在完成两年进修后的头3年临床实践中所做的尿道下裂手术的结果。
对2004年7月至2007年8月间两位外科医生(DF和JC)治疗的所有尿道下裂患者进行回顾性病历审查。这两位医生在两个不同机构(约翰·霍普金斯医院和德克萨斯儿童医院)完成了为期两年的小儿泌尿外科进修。记录尿道下裂的程度、患者年龄、修复类型、随访情况以及并发症。阴茎中段和远端尿道下裂归类为远端型。
总共对187例患者进行了手术。两位医生在手术数量和并发症方面无显著差异。发现远端尿道下裂149例,近端尿道下裂29例,阴茎阴囊型或会阴型尿道下裂9例,这9例患者需要进行两期修复。远端尿道下裂采用背侧包皮板切开加尿道成形术(TIP)修复112例,尿道口前移阴茎头成形术(MAGPI)修复37例。所有近端病变均采用TIP修复。所有患者在术后1 - 2周、6个月和12个月进行复查。10例患者出现瘘管(远端3例,近端4例,两期修复3例),总体瘘管发生率为5.3%。3例远端修复和1例两期修复出现尿道口梗阻,1例近端修复出现憩室。MAGPI修复未出现并发症。除1例之外,所有并发症均在一次手术中成功修复。
经过数十年手术创新开创的现代尿道下裂手术技术如今能够成功传授给新一代经过专科培训的小儿泌尿外科医生。现代小儿专科进修培训使得远端尿道下裂修复的瘘管发生率最低可达2.8%。近端尿道下裂手术仍然更具挑战性,一期修复并发症发生率为13.8%,两期修复并发症发生率为33.3%。
