title: Bilateral stones as a cause of acute renal failure in the emergency department.
abstract: BACKGROUND
  Acute renal failure (ARF) due to obstructive uropathy is a urological emergency. The standard radiological investigations in the emergency setting include X-ray, ultrasonography and computed tomography. But occasionally the cause of obstruction may be elusive.
  
  
  METHODS
  We present a case of obstructive uropathy due to bilateral stones presenting as acute renal failure. The patient underwent successful shock wave lithotripsy (SWL) for dissolution of calculi.
  
  
  RESULTS
  The patient was successfully treated, and reported asymptomatic in a follow-up.
  
  
  CONCLUSIONS
  Close collaboration between nephrological, urological, and radiological services is required.
