To evaluate the success rates of a simple posthypospadias urethrocutaneous fistula repair.
We evaluated children who underwent urethrocutaneous fistula closure by means of a simple standard technique in which the fistula tract was dissected to its base and resected and the urethral defect closed with a single layer of continuous sutures and covered with local subcutaneous tissue. No urethral stents or catheters were used, and the patients were discharged on the same day. Excluded were children who underwent fistula repair by a different technique, revision hypospadias repair for fistula, or concomitant meatoplasty for meatal stenosis. Study endpoints were fistula recurrence and the need for further penile surgery other than fistula repair.
Seventy-two children underwent 81 repairs. The mean follow-up was 7.9 years. Recurrence occurred in 17 cases (21%). Seven children (9%) underwent penile surgery other than fistula repair, including meatoplasty (n = 5) and re-do hypospadias repair for a diagnosis other than fistula recurrence (n = 2). There was no significant difference in recurrence rate between large and small fistulas, coronal or more proximal fistulas, or children w/wo prior fistula repairs.
Standard fistula closure solely by adjacent tissues yielded success rates of 79% after long-term follow-up. This repair can be safely offered with the expectation of similar results for a variety of urethrocutaneous fistulas in children.
评估一种简单的尿道下裂后尿道皮肤瘘修复的成功率。
我们评估了通过简单的标准技术进行尿道皮肤瘘闭合的儿童,在该技术中,瘘管被解剖到其基底并切除,尿道缺损用单层连续缝线闭合,并覆盖局部皮下组织。未使用尿道支架或导管,患者当天出院。排除了采用不同技术修复瘘管、修复瘘管后再次进行尿道下裂修复或同时进行尿道口狭窄成形术的儿童。研究终点为瘘管复发和需要进行除瘘管修复以外的阴茎手术。
72 名儿童进行了 81 次修复。平均随访时间为 7.9 年。17 例(21%)出现复发。7 名儿童(9%)进行了阴茎手术,除了瘘管修复外,还包括尿道口成形术(n=5)和因非瘘管复发而再次进行尿道下裂修复(n=2)。大、小瘘管、冠状或更靠近近端的瘘管或既往有瘘管修复的儿童之间,复发率无显著差异。
单纯通过相邻组织进行标准的瘘管闭合,在长期随访后成功率为 79%。对于儿童的各种尿道皮肤瘘,可以安全地提供这种修复方法,并期望获得类似的结果。
