Urothorax

From Dog

Urothorax is defined as the presence of urine within the thoracic cavity.

In canine medicine, this is rarely observed but has been reported with concurrent uroabdomen following severe blunt trauma due to motor vehicle accidents[1] in cases of severe motor vehicle accidents..

The presence of urine within the pleural cavity incites a rapid pneumonitis.

Diagnosis is usually established by thoracocentesis and comparison of aspirate creatinine concentration:serum creatinine. Levels >2:1 are usually diagnostic.

Blood tests usually reveal azotemia and hyperkalemia.

Medical intervention is usually instituted initially to correct hyperkalemia, following by surgical correction of the urinary bladder deficit and secondary traumatic diaphragmatic hernia.
