A 12-year-old girl complained of left flank pain 4 months after the onset of symptoms of polyarthritis nodosa with hypertension, multiple neuritis and impaired renal function. Intravenous pyelography (IVP) revealed no stone. Several months later the flank pain recurred, and IVP now showed a calcified stone midway in the left ureter. Ureterolithotomy was performed, and a 3 cm long stone embedded in the mucosa was removed. Two months postoperatively IVP showed severe ureteric obstruction due to stenosis at the level of the incision. Dilation of the stricture was accomplished with a 4 mm balloon, and further dilation 2 weeks later with a 6 mm balloon. A third dilation was performed with a 4 mm balloon. At examination 3 months later the girl was free from symptoms and IVP with forced diuresis was normal, as were the findings after 6 more months. Transluminal balloon dilation of postoperative ureteral strictures in children should be considered as an alternative to surgery.
一名12岁女孩在结节性多关节炎合并高血压、多发性神经炎及肾功能损害症状出现4个月后，诉说左侧胁腹疼痛。静脉肾盂造影（IVP）未显示结石。数月后胁腹疼痛复发，此时IVP显示左输尿管中段有一钙化结石。施行输尿管切开取石术，取出一枚嵌入黏膜的3厘米长结石。术后2个月IVP显示因切口处狭窄导致严重的输尿管梗阻。用4毫米球囊扩张狭窄部位，2周后用6毫米球囊进一步扩张。第三次用4毫米球囊进行扩张。3个月后检查时，女孩无症状，强制利尿下的IVP正常，再过6个月后的检查结果也正常。儿童术后输尿管狭窄的腔内球囊扩张术应被视为手术的一种替代方法。
