一名79岁女性，表现为肉眼血尿。2年前因G2 pT2型肾细胞癌行右侧根治性肾切除术。静脉肾盂造影显示左侧输尿管充盈缺损。全身检查未发现其他转移灶。行部分输尿管切除术和端对端输尿管输尿管吻合术。组织学显示转移性透明细胞癌与原发性肾肿瘤一致。术后6个月，患者血清肌酐稳定在1.6 mg/dl，病情良好，无复发迹象。肾细胞癌单发转移至对侧肾盂或输尿管极为罕见，仅报道7例。我们在此描述本病例并回顾相关文献。
A 79-year-old woman presented with gross hematuria. She had undergone a right radical nephrectomy 2 years previously for G2 pT2 renal cell carcinoma, clear cell variant. Intravenous pyelography showed a filling defect in the left ureter. Systemic work-up demonstrated no evidence of other metastases. Partial uretectomy and end-to-end ureteroureterostomy were performed. Histology showed metastatic clear cell carcinoma consistent with the primary renal tumor. Six months after surgery, her serum creatinine was stable at 1.6 mg/dl and she was doing well without evidence of recurrent disease. Solitary metastasis of renal cell carcinoma to the contralateral renal pelvis or ureter is extremely rare, with only 7 cases having been reported. We herein describe the present case and review the relevant literature.
