A case of contralateral ureteral metastasis from renal cell carcinoma is reported. A 52-year-old man underwent left nephrectomy for renal cell carcinoma of November 20, 1986. He was clinically asymptomatic for 4 years 8 months after the operation. He was admitted on August 14, 1991, because of right loin pain. Right retrograde pyelography and percutaneous pyelography showed a filling defect in the right ureter at the level of L3. After the right ureter was explored, the tumor lesion of ureter was resected and end to end anastomosis of the ureter was performed. Histopathologic examination showed a metastatic clear cell carcinoma consistent with a renal primary. The contralateral ureteral metastasis from renal cell carcinoma is very rare and only 15 cases have been reported previously.
报告1例肾细胞癌对侧输尿管转移病例。一名52岁男性于1986年11月20日因肾细胞癌接受左肾切除术。术后4年8个月他临床无症状。1991年8月14日，他因右腰部疼痛入院。右逆行肾盂造影和经皮肾盂造影显示L3水平右侧输尿管有充盈缺损。探查右侧输尿管后，切除输尿管肿瘤病变并进行输尿管端端吻合。组织病理学检查显示为转移性透明细胞癌，与肾原发性肿瘤一致。肾细胞癌对侧输尿管转移非常罕见，此前仅报道过15例。
