Postoperative Acute Renal Failure: Etiologies and Prognostic Factors

Postoperative acute renal failure is a rare complication in the surgical context. It is the consequence of a significant and prolonged decrease in the glomerular filtration rate, leading to a failure to eliminate nitrogen catabolism products and a hydroelectrolytic disorder. Early recognition of risk factors and prevention of spinal cord ischemia are the two fundamental elements in the management of postoperative renal failure.
