Abstract

We present an exceptionally rare scenario of obstructive uropathy secondary to a ureteral mass. This case details a 68-year-old female with metastatic stage IIID melanoma of the right heel found to have a two cm right proximal ureteral mass with associated hydronephrosis. Pathology from ureteroscopic biopsy revealed metastatic melanoma to the ureter, creating a unique treatment quandary.

Keywords: Hydronephrosis; Immunotherapy; Metastatic melanoma; Obstructive uropathy.
