We describe our experience with 2-stage proximal hypospadias repair. We report outcomes, and patient and procedure characteristics associated with surgical complications.
We retrospectively studied patients with proximal hypospadias who underwent staged repair between January 1993 and December 2012. Demographics, preoperative management and operative technique were reviewed. Complications included glans dehiscence, fistula, meatal stenosis, nonmeatal stricture, urethrocele/diverticula and residual chordee. Cox proportional hazards model was used to evaluate the associations between time to surgery for complications and patient and procedure level factors.
A total of 134 patients were included. Median patient age was 8.8 months at first stage surgery and 17.1 months at second stage surgery, and median time between surgeries was 8 months. Median followup was 3.8 years. Complications were seen in 71 patients (53%), with the most common being fistula (39 patients, 29.1%). Reoperation was performed in 66 patients (49%). Median time from urethroplasty to surgery for complication was 14.9 months. Use of preoperative testosterone decreased risk of undergoing surgery for complication by 27% (HR 0.73, 95% CI 0.55-0.98, p = 0.04). In addition, patients identified as Hispanic were at increased risk for undergoing surgery for complications (HR 2.40, 95% CI 1.28-4.53, p = 0.01).
We review the largest cohort of patients undergoing 2-stage hypospadias repair at a single institution. Complications and reoperation rates were approximately 50% in the setting of complex genital reconstruction.
我们描述两阶段近端尿道下裂修复术的经验。我们报告手术并发症相关的结果、患者及手术特征。
我们回顾性研究了1993年1月至2012年12月间接受分期修复的近端尿道下裂患者。回顾了人口统计学资料、术前管理及手术技术。并发症包括龟头裂开、瘘管、尿道口狭窄、非尿道口狭窄、尿道膨出/憩室及残留阴茎弯曲。采用Cox比例风险模型评估并发症手术时间与患者及手术层面因素之间的关联。
共纳入134例患者。第一阶段手术时患者中位年龄为8.8个月,第二阶段手术时为17.1个月,两次手术之间的中位时间为8个月。中位随访时间为3.8年。71例患者(53%)出现并发症,最常见的是瘘管(39例,29.1%)。66例患者(49%)接受了再次手术。从尿道成形术到并发症手术的中位时间为14.9个月。术前使用睾酮使并发症手术风险降低27%(风险比0.73,95%置信区间0.55 - 0.98,p = 0.04)。此外,确定为西班牙裔的患者并发症手术风险增加(风险比2.40,95%置信区间1.28 - 4.53,p = 0.01)。
我们回顾了在单一机构接受两阶段尿道下裂修复术的最大患者队列。在复杂生殖器重建的情况下,并发症和再次手术率约为50%。
