INTRODUCTION
To assess the effectiveness of buccal mucosa patch graft in the treatment of recurrent large urethrocutaneous fistula after hypospadias repair.
MATERIALS AND METHODS
A free graft of buccal mucosa was used for closure in 7 boys (mean age 4.8 years) with large (>4 mm) urethocutaneous fistula. Four fistulas were in the midshaft, 2 of them penoscrotal and 1 coronal type. All patients had undergone at least two previous unsuccessful fistula repairs, and 3 of them had undergone three attempts for closure. Fistula repairs were similar in all cases.
RESULTS
The repair was successful in 6 out of 7 cases, and in these cases the urinary stream was good after the removal of the catheter. The unsuccessful case was the coronal one.
CONCLUSION
Based on our experience it seems that in cases with recurrent large fistula after hypospadias reconstruction, the use of buccal mucosa patch graft for closure is a good treatment choice.
引言
评估颊黏膜补片移植治疗尿道下裂修复术后复发性大型尿道皮肤瘘的有效性。
材料与方法
7名男孩（平均年龄4.8岁）患有大型（>4毫米）尿道皮肤瘘，采用游离颊黏膜移植进行闭合。4例瘘位于阴茎体部，其中2例为阴茎阴囊型，1例为冠状沟型。所有患者此前至少经历过两次瘘修复失败，其中3例曾尝试三次闭合瘘口。所有病例的瘘修复方法相似。
结果
7例中有6例修复成功，这些病例拔除导尿管后尿流良好。失败的病例是冠状沟型的那例。
结论
根据我们的经验，对于尿道下裂重建术后复发性大型瘘的病例，使用颊黏膜补片移植进行闭合是一种不错的治疗选择。
