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. 相似文献
