An 11- day- old Arabian colt was admitted to the veterinary teaching hospital with chief compliant of generalized weakness, moderate muscle fasciculations and progressive abdominal distention. Abdominal ultrasonography revealed a large hypoechoic area compatible with liquid in the abdomen, believed to be caused by uroperitoneum. Serum biochemical analysis revealed the foal suffured from hyponatremia, hypochloremia, hyperkalemia and azotemia. Creatinine concentration of the peritoneal fluid was 9.6 mg/dlit and the peritoneal fluid to plasma creatinine ratio was 2.83, confirming a diagnosis of uroperitoneum. An exploratory laparotomy was performed to investigate the cause of the uroperitoneum. Based on the surgical exploration, a diagnosis of bilateral ureteral defects was made. According to histopathologic findings at margins of the lesions, such as fibrin deposits and presence of neutrophils, traumatic insults have been accounted for the utreteral defects in this foal.
