Abstract:
Secondary malignancies of the ureter are uncommon. We report the diagnosis and management of metastatic colon cancer to the bifurcation of a bifid ureter. A 59-year-old man presented with diffuse metastasis with right hydronephrosis in both renal moieties of a partially duplicated system and an enhancing lesion within the proximal common ureter. Ureteral biopsy was positive for colorectal adenocarcinoma. The patient was subsequently started on palliative chemoradiation. The ureter is a rare location for hematogenous/lymphatic metastases. When a ureteral mass is present on imaging, ureteroscopy should be performed to characterize the extent of tumor and to rule out secondary malignancy.
