title: Magnetic Resonance Urography in Obstructive Uropathy.
abstract: BACKGROUND
  Urinary obstruction is one of the few reversible causes of renal failure. Early diagnosis and treatment can salvage the kidney. Presently intravenous urography, ultrasonography, computed tomography and magnetic resonance imaging are in vogue to detect the cause and demonstrate the site of obstruction.
  
  
  METHODS
  An evaluation of imaging technique in obstructive uropathy was undertaken in a group of 25 patients.
  
  
  CONCLUSIONS
  Magnetic resonance urography delivered highest accuracy amongst the techniques studied.
