The metastasis of renal cell carcinoma to the contralateral ureter: a case report / 中华泌尿外科杂志

ABSTRACT

The metastasis of renal cell carcinoma to the ureter is a rare phenomenon, and synchronal detection of metastasis to the contralateral ureter is a rarer phenomenon. A 62-year-old male patient with painless hematuria was examined and detected a renal cell carcinoma on the right kidney and bleeding from the left ureter. Ureteroscopy revealed a tumor in the left upper ureter, and biopsy suggested clear cell carcinoma. Laparoscopic radical nephrectomy was performed to resect the right renal cell carcinoma, and the pathology revealed a clear cell carcinoma, with Fuhrman nuclear grade 2 class. The ureteral tumor was resected 3 months later and the pathology revealed renal clear cell carcinoma. Sunitinib was used for 37 months, and there was no tumor recurrence or metastasis so far.
