Plain-English summary
A 3-year-old male mixed breed dog was brought in for chronic vomiting and diarrhea. An abdominal ultrasound showed a large mass in the abdomen that was pressing on the left ureter, causing a blockage and swelling of the kidney (hydronephrosis). Tests confirmed that the mass was large cell lymphoma, a type of cancer. This case highlights a rare instance where lymphoma directly invaded the ureter. The dog’s treatment options would typically include chemotherapy, but the specific outcome isn't detailed in the study.

Abstract
A 3-year-old male neutered mixed breed dog was presented for chronic vomiting and diarrhea. Abdominal ultrasound revealed a large amorphous, heterogeneous mass within the left mid to caudal abdomen most consistent with medial iliac lymph node. It appeared to invade the left ureter and extend distally causing ureteral obstruction and hydronephrosis. Concurrent additional ultrasound findings were consistent with metastatic or multicentric neoplasia. Fine needle aspirates of the lymph node and spleen both confirmed large cell lymphoma. These findings present evidence of lymphoma invading directly from an organ into the ureter which has not previously been reported in dogs.
