Calyceal diverticula are non-secretory transitional-epithelium lined cavities that are connected to the collecting system through a small ostium. They are rarely seen in young children. Although most remain asymptomatic, the presence of stagnant urine can result in infection, stone formation and pain. Treatment may consist of percutaneous ablation or open surgical excision. Failure of the ostium to completely seal can result in a persistent leak. We present a case of a massive calyceal diverticulum in a child who developed a postsurgical nephrocutaneous fistula recalcitrant to conservative management that was successfully managed with injection of fibrin glue.
肾盏憩室是由非分泌性移行上皮衬里的腔隙，通过一个小开口与集合系统相连。它们在幼儿中很少见。尽管大多数患者无症状，但尿液潴留可导致感染、结石形成和疼痛。治疗方法包括经皮消融或开放手术切除。开口未能完全封闭可导致持续性渗漏。我们报告一例儿童巨大肾盏憩室病例，该患儿术后发生肾皮肤瘘，保守治疗无效，通过注射纤维蛋白胶成功治愈。
