Plain-English summary
A 12-year-old spayed female goldendoodle was brought to the vet because she was drinking a lot of water and losing weight. Tests showed a large mass in her abdomen, specifically in the left ureter, which was causing additional complications. The vet performed surgery to remove the affected ureter and part of the bladder, as well as a mass from the liver. The results confirmed a rare type of cancer called ureteral hemangiosarcoma and another liver cancer. While chemotherapy was suggested, the owner chose not to pursue it.

Abstract
BACKGROUND: Primary ureteral neoplasia in dogs is extremely rare. To the best of the authors' knowledge, this is the second documented case of a primary ureteral hemangiosarcoma. This case report describes the clinical and pathological findings of a primary distal ureteral hemangiosarcoma. CASE PRESENTATION: A 12-year-old spayed female goldendoodle was presented with a history of polyuria and weight loss. Abdominal radiographs revealed a large cranial abdominal mass. Abdominal ultrasound and computed tomography (CT) identified a left sided distal ureteral mass with secondary hydroureter and a left lateral hepatic mass with no evidence of connection or diffuse metastasis. A left ureteronephrectomy, partial cystectomy, and left lateral liver lobectomy were performed. Histopathology was consistent with primary ureteral hemangiosarcoma and a hepatocellular carcinoma. Adjunctive therapy including chemotherapy was discussed but declined. CONCLUSION: Due to its rarity, the authors of this case presentation believe that ureteral hemangiosarcoma should be included as a differential diagnosis when evaluating a ureteral mass. With the unknown, and suspected poor prognosis, routine monitoring with adjunctive therapy should be considered.
