Plain-English summary
A 5-year-old female dog developed a noticeable lump in her right side after having surgery to remove her ovaries and uterus. The vet used ultrasound to find a fluid-filled mass near her right kidney, which indicated a condition called urinoma (a type of fluid buildup). During surgery, they discovered the mass was caused by urine leaking from a cut ureter. After confirming the diagnosis, the vet was able to treat the issue, and the dog was expected to recover well.

Abstract
A urinoma is an encapsulated extravasation of urine. In this case history report, the radiographic and ultrasonographic features of a urinoma in a dog are described. The dog presented with a palpable mass in the right flank which developed following ovariohysterectomy. Urinoma was considered when ultrasonographically, a sharply marginated, anechoic mass immediately caudal to the right kidney, ipsilateral hydroureter and hydronephrosis were detected. Extravasation of contrast medium was not seen during excretory urography. A fluid‐filled retroperitoneal mass adjacent to a transected ureter was found at exploratory laparotomy. The diagnosis of urinoma (para‐ureteral pseudocyst) and hydronephrosis was confirmed histopathologically.
