Ureteric duplication is a rare anomaly in the urinary tract, with an incidence of 0.5% to 3%. Bilateral double ureters are even rarer, occurring in 1 of 500 individuals. A 25-year-old man presented with right flank pain and nausea. Physical examination revealed tenderness at the right renal angle. Urinalysis demonstrated microscopic hematuria, and Ultrasound showed enlargement in the lower pole of the right kidney, while the upper pole appeared normal. Intravenous pyelography confirmed bilateral complete ureter duplication. However, after a week of observation, a 5 mm calcium oxalate stone was passed, and this event demonstrated the underlying cause of hydronephrosis in the lower pole of the right kidney. Bilateral complete ureter duplication is a rare anomaly in the urinary tract. To our knowledge, the presence of bilateral complete ureter duplication with a single stone in the right limb of the right double ureter is a unique case that has not been reported in the existing literature.
输尿管重复畸形是一种罕见的泌尿系统异常，发病率为0.5%至3%。双侧双输尿管更为罕见，每500人中会有1人出现。一名25岁男性出现右侧腰痛和恶心症状。体格检查发现右肾角有压痛。尿液分析显示镜下血尿，超声显示右肾下极增大，而上极外观正常。静脉肾盂造影证实双侧完全性输尿管重复畸形。然而，经过一周的观察，排出了一颗5毫米的草酸钙结石，这一情况揭示了右肾下极肾积水的潜在病因。双侧完全性输尿管重复畸形是一种罕见的泌尿系统异常。据我们所知，双侧完全性输尿管重复畸形且右侧双输尿管右侧分支中有单一结石的情况是一个独特病例，现有文献中尚未有报道。
