BackgroundThere are only a few publications in the medical literature reporting on complication rates in proximal hypospadias surgery, particularly with regard to long-term follow-up.MethodsOver a 17.5-year period, we operated 100 patients with penoscrotal, scrotal and perineal hypospadias. Sixty-four had a single-stage repair, including 15 who received a buccal mucosa inlay “Snodgraft” repair. Thirty-six had a two-stage Bracka repair of which 19 received buccal or lower lip grafts and 17 had preputial grafts. Overall, 34 patients received buccal grafts. The median follow-up was eight years (range 1–16 years). Three patients were operated for residual chordee years later.ResultsUrethral fistulae occurred in a total of 26/100 (26.0%) cases, meatal stenosis in 16/100 (16.0%), wound breakdown in six (6.0%) and graft failure in one (1.0%). The fistula rate after the single-stage approach was 15/64 (23.4%), whereas it was 11/36 (30.6%) following two-stage repair (P = 0.4811).ConclusionsProximal hypospadias remains a challenging condition to treat. It is possible to perform a single-stage repair in 64.0% of cases. This brings down the median number of operations to only two. Lower lip grafts were used in 34.0% but are now used in redo-surgeries only. Our fistula rate was 26.0% but has decreased significantly in recent years.Level of evidenceLevel III.  相似文献

目的:总结口腔黏膜背侧游离移植结合阴茎带蒂皮瓣腹侧覆盖尿道扩大成形术治疗阴茎部尿道狭窄的临床效果及经验。方法:选择北京积水潭医院泌尿外科2015年11月至2018年10月采用口腔黏膜背侧游离移植结合阴茎带蒂皮瓣腹侧覆盖尿道扩大成形术治疗阴茎部尿道狭窄患者22例的病例资料进行回顾性分析。所有患者均无术前尿瘘等合并症,均为单纯性单处阴茎部尿道狭窄,其中医源性狭窄14例(63.6%)、感染性狭窄2例(9.1%)、特发性狭窄6例(27.3%)。术中均从腹侧纵行切开尿道狭窄段,先采用游离口腔黏膜做狭窄段背侧嵌式修补,腹侧采用纵行阴茎带蒂皮瓣(Orandi皮瓣)覆盖修补,留置16F或14F硅胶尿管,3周后拔除尿管并行尿道造影及膀胱镜检查。术后最大尿流率≥15 mL/s且不需要尿道扩张等外科干预可视为手术成功。结果:本组患者年龄平均52.6(18~73)岁。患者尿道狭窄均位于前尿道阴茎部,长度平均5.3(2.5~10.0) cm,术前平均最大尿流率6.7 mL/s。口腔黏膜取材长度平均5.5(3.2~10.5) cm,阴茎皮瓣长度平均6.0(3.5~11.0) cm。手术时间平均225(150~420) min,术中平均估计失血量53(20.0~110.0) mL。采用颊黏膜19例(86.4%), 舌黏膜3例(13.6%),其中双侧颊黏膜取材5例(22.7%)。平均随访20.5(5~51)个月,术后6个月平均最大尿流率21.2(15~32) mL/s。术后尿瘘形成1例、再狭窄2例,手术成功率为81.8%(18/22), 2例再狭窄患者1例再次行尿道成形术后治愈,另1例行定期尿道扩张治疗。术后感染2例,表现为尿道口脓液溢出、阴茎肿胀,对症处理后治愈。局部皮肤坏死1例,给予保守治疗成功。尿瘘患者行瘘修补术后治愈。结论:口腔黏膜背侧游离移植结合阴茎带蒂皮瓣腹侧覆盖尿道扩大成形术治疗阴茎部尿道狭窄22例平均随访20.5个月,手术成功率为81.8%,临床效果明确,适用于严重前尿道阴茎部狭窄且局部阴茎皮肤状况良好的患者。  相似文献

Objective

To describe our technique of retrograde pericatheter urethrography (RPU) and its clinical use after urethroplasty.

Subjects and methods

Between January 2008 and December 2013, 387 patients with urethral stricture underwent urethroplasty at our center. A total of 343 of these patients underwent RPU 3 weeks post-operatively. For this retrospective study their files were evaluated with regard to: demographics, duration of symptoms, site, mean length of stricture, type of surgery, RPU findings, contrast-medium related complications and need of re-intervention. The eventual surgical success was defined as asymptomatic voiding with no clinical evidence of residual stricture (good flow rate and no residual urine) until the last follow up.

Results

Follow up ranged from 8 to 41 (mean 28) months. The mean duration of symptoms was 4.8 months. The mean stricture length, as seen on radiography, was 2.1 cm. 183 patients (53.3%) underwent anastomotic urethroplasty, while 160 (46.6%) underwent substitution urethroplasty. RPU showed urethral healing in 292 (85.2%) and contrast extravasation in 51 (14.8%) patients. No contrast-medium related complications were reported. Re-intervention was needed in 7.2% (21/292) of the patients who showed normal urethral healing and in 74.5% (38/51) of the patients who showed contrast extravasation on RPU. By the time of the last follow up the overall success rate was 82.7% (284/343 patients).

Conclusion

RPU is the most useful radiological diagnostic method for evaluating the appropriate time for catheter removal after urethroplasty. It helps to assess urethral healing and patency after urethroplasty. Prolonged catheterization in patients showing contrast extravasation may be helpful.  相似文献

目的 探讨尿道下裂分期修复的价值及策略.方法 回顾性分析重型及复杂性尿道下裂163例.按手术方式分为2组,分期修复组:阴茎下曲矫正及尿道重建分期完成,共46例,其中重型尿道下裂31例,复杂性尿道下裂15例.一期修复组(对照组):阴茎下曲矫正及尿道重建一期完成,共117例,其中重型尿道下裂108例,复杂性尿道下裂9例.结果 分期修复组中阴茎严重畸形及局部修复材料缺乏等不利因素多见,其修复条件较一期修复组差.重型尿道下裂分期修复组远期阴茎下曲的发生率明显低于一期修复组(P<0.05),分期修复组仅1例有轻度阴茎下曲(3.2%),而一期修复组23例出现阴茎下曲(21.3%),7例合并阴茎扭转,其中20例于阴茎腹侧可及弓弦状短缩的尿道,19例再次手术(17.6%).2组尿瘘、尿道狭窄及尿道憩室的发生率比较差异均无统计学意义(P均>0.05).复杂性尿道下裂分期修复组尿瘘的发生率明显低于一期修复组,尿瘘率分别为20.0%和66.7%(P<0.05).远期阴茎下曲、尿道狭窄及尿道憩室的发生率比较差异均无统计学意义(P均>0.05).结论 分期修复手术相对简单,效果好,适用于重型或复杂性尿道下裂的矫治,尤其是修复条件不良的病例.术式的选择应根据阴茎及其皮肤条件,结合术者自身技术及经验进行,避免勉强而为的一期修复手术.  相似文献

We report the follow-up of 47 patients with penile hypospadias who were treated by the Scuderi procedure between 1988 and 1998 at Sahlgrenska University Hospital, Göteborg, Sweden. Forty of the patients (85%) had had no previous operations, while the remaining seven had had meatotomy with chordectomy only, or an unsuccessful Dennis-Browne procedure. Hypospadias was distal in 35 (74%), mediopenile in 8 (17%), and proximal in 4 (9%); 21 (45%) showed signs of curvature. After a Scuderi urethroplasty one patient developed a fistula (2%) and 4 developed mild stenosis. The early success rate was therefore 42/47 (89%) and this later increased to 46/47 (98%) after non-surgical treatment of the stenoses. The results support the use of the Scuderi procedure for correction of primary and secondary penile hypospadias with a low complication rate.  相似文献
