Clear cell renal cancer metastasis in the contralateral ureter: a case report

Clear cell renal carcinoma is known for its propensity for metastatic spread. Common sites of metastasis are the lungs, bones, lymph nodes, liver, adrenals and brain, but all organs can be affected. Contralateral ureteral metastasis is a rare phenomenon, and only a few cases have been reported in the literature.

We present the case of a 58-year-old Caucasian patient with a single contralateral ureteral metastasis of a clear cell renal carcinoma.

Ureteral metastasis of clear cell renal carcinoma is very rare, and there is no well-established treatment. For patients with low metastatic spread/volume, the aim should be to preserve kidney function, and thus metastasectomy should be considered.
