A 4-year-old girl with the history of repeated urinary tract infections was referred from the pediatric department to our department on January, 1987. Under the diagnosis of right ectopic ureterocele of everting type with complete duplication of renal unit, the one-stage operation, that is, right hemi-nephroureterectomy with complete excision of the ureterocele and ureteral stump was carried out on January 27, 1987. Reimplantation of the orthotopic mate ureter was done because of injury to lower part of the mate ureter during operation, although reflux of the mate ureter did not exist. After the operation, the voiding symptom became better except for large residual urine volume (300 ml). In order to protect renal function, intermittent catheterization was carried out. Two years and 8 months after that operation, residual urine volume was reduced to 20 ml. Judging from the literature and our experience, if the patient is not in a severe condition, we recommend one-stage operation, that is, total correction (a single operation designed to correct abnormalities of the upper and lower urinary tract) for ectopic ureterocele in children.
一名有反复尿路感染病史的4岁女孩于1987年1月从儿科转诊至我科。诊断为右外翻型输尿管囊肿伴肾单位完全重复，于1987年1月27日进行了一期手术，即右半肾输尿管切除术，同时完全切除输尿管囊肿和输尿管残端。由于术中对健侧输尿管下段造成损伤，尽管健侧输尿管不存在反流，仍对其进行了原位再植。术后，除残余尿量较大（300ml）外，排尿症状有所改善。为保护肾功能，进行了间歇性导尿。该手术后两年零八个月，残余尿量降至20ml。根据文献和我们的经验，如果患者病情不严重，我们建议对儿童异位输尿管囊肿进行一期手术，即完全矫正术（一种旨在矫正上尿路和下尿路异常的单一手术）。
