ULTRASONOGRAPHIC DIAGNOSIS OF HYDRONEPHROSIS IN A COW

A ruptured right kidney was diagnosed in a cow with clinical signs of mild intermittent abdominal pain and no laboratory evidence of renal failure. Ultrasonography of the kidneys demonstrated unilateral hydronephrosis and retroperitoneal fluid. A unilateral nephrectomy using a staple instrument was performed. Ultrasonographic evaluation allowed an early and accurate diagnosis with subsequent successful surgical intervention and treatment.
