A case of metastatic seminoma to the ureter is presented. The metastasis formed a polypoid intraluminal mass that led to complete obstruction of the ureter, leading to advanced hydronephrosis of the kidney. This is the second case in the world literature of a primary testicular tumor metastasizing to the ureter.
