Uroperitoneum

As Uroperitoneum refers to the accumulation of urine in the abdomen in mammals. The most common cause in humans is an injury to the urinary bladder . But injuries to the ureter , rarely a ruptured persistent urachus can trigger a Uroperitoneum. The urine causes peritonitis . In addition, urinary substances accumulate in the blood ( azotemia ) because the substances excreted by the kidneys are reabsorbed in the abdomen.

In addition to azotemia, there are electrolyte disorders ( hyperkalaemia , hyponatremia , hypochloremia ). For dogs, a creatinine value in the abdominal cavity fluid that is twice that of the blood serum and a potassium value that is 1.4 times the serum value are diagnostic. In humans, a retrograde cystography is usually performed for diagnosis , with which the flow of urine into the abdomen can be detected.

Treatment is by surgically repairing the leak in the urinary tract.
