A 5-year-old girl underwent an elective left pyeloplasty for pelvoureteric junction obstruction (PUJO). At laparoscopy, two ureters were seen to be draining a left duplex kidney, with a PUJO of the lower moiety. Interestingly, however, the upper moiety ureter was bifurcating to drain both upper and lower moiety as well. All the preoperative investigations were suggestive of a single system. The ureteric bifurcation of this type has not been reported so far. It is of paramount importance to demonstrate anatomy clearly at an operation to prevent risk to the less defined ureters.
一名5岁女孩因肾盂输尿管连接部梗阻（PUJO）接受了择期左侧肾盂成形术。在腹腔镜检查中，发现两条输尿管引流左侧重复肾，下极存在PUJO。然而，有趣的是，上极输尿管也分叉以同时引流上极和下极。所有术前检查均提示为单一系统。迄今为止，尚未报道过这种类型的输尿管分叉情况。在手术中清晰显示解剖结构对于防止对不太明确的输尿管造成风险至关重要。
