Kidney and upper urinary tract anomalies account for 23% of all birth defects. Partial duplication is slightly more prevalent than complete, 70% and 30%, respectively. A very low fusion of ureters, i.e., in the intramural part, is a rarer case. As a result, the joint section is very short (<1 cm) and may be invisible for radiological diagnosis. This case shows a rare variation of incomplete bifid ureter coupled with urolithiasis, which should be taken into account by the physician when determining urolithiasis treatment.
肾脏和上尿路异常占所有出生缺陷的23%。部分重复比完全重复略为常见，分别为70%和30%。输尿管的极低融合，即在壁内部位，是一种较罕见的情况。因此，联合段非常短（<1厘米），可能在放射学诊断中不可见。本病例显示了不完全双输尿管合并尿路结石的罕见变异，医生在确定尿路结石治疗方案时应予以考虑。
