Metachronous presentation of metastatic renal cell carcinoma (RCC) to the ureter is extremely rare. We report a solitary metachronous metastatic RCC in the contralateral ureter 14 months after right radical nephrectomy for Fuhrman grade 2 pT3a clear cell disease after the patient re-presented with gross hematuria. The proximal left ureteral lesion was excised followed by ileal-ureteral interposition. Pathologic examination confirmed metastatic RCC. To date, only 51 cases of metastatic RCC to the ureter have been reported, with only 6 occurring metachronously in the contralateral ureter. Also, we report the presence of focal extramedullary hematopoiesis occurring within this metastatic lesion.
转移性肾细胞癌（RCC）异时性转移至输尿管极为罕见。我们报告1例在因Fuhrman 2级pT3a透明细胞癌行右侧根治性肾切除术后14个月，对侧输尿管出现孤立性异时性转移性RCC的病例，该患者再次出现肉眼血尿。切除了左侧输尿管近端病变，随后行回肠-输尿管间置术。病理检查证实为转移性RCC。迄今为止，仅报告了51例RCC转移至输尿管的病例，其中仅6例为对侧输尿管异时性转移。此外，我们报告了在该转移性病变内存在局灶性髓外造血。
