Contrast induced nephropathy is the third most common cause of hospital-acquired acute renal failure. The incidence of contrast induced nephropathy in the general population is 0.6% to 2.3%, but when focusing on specific high-risk patients the incidence can increase to more than 40%. Studies suggest that intravenous hydration is the most effective strategy to prevent contrast induced nephropathy. Hydration is inexpensive and is usually risk-free. Administration of optimal fluids before and after the contrast procedure allows for increased urine output and improved outcomes.
