title: Acute renal impairment following use of intravenous contrast agent: A case report and reminder for increased awareness of the problem.
abstract: OBJECTIVE
  Contrast-induced nephropathy is one of the adverse reactions to the use of radiocontrast media. Its incidence can be reduced if preventive measures are instituted. This report presents a case of acute renal impairment following use of radiocontrast media.
  We report a case of an elderly hypertensive diabetic who developed acute renal impairment within 24 hours of undergoing an intravenous urography. He was not a known asthmatic and had no previous history of allergy. His renal function improved subsequently with hydration, diuretics and strict input/output monitoring. He was discharged after 23 days in hospital and renal function returned to pre-morbid state 3 months after discharge.
  
  
  CONCLUSIONS
  The report is a reminder of the possibility of nephropathy associated with the use of intravascular contrast media. There is need for extra care to be taken to identify risk factors in patients that are to undergo intravascular contrast studies and adequate attention paid to these.
