The recurrence of renal cell carcinoma (RCC) in the remnant urothelium is rare, and in this paper we report a case in which the condition recurred in the remnant ureter five years after radical nephrectomy. The recurrent mass was seen on retrograde ureterograms as polypoid filling defect, and on CT images as soft tissue mass-like density. In view of the radiologic and pathologic findings, we believe that in this case, the mechanism of intraureteral recurrence was direct implantation.
