[Validation of a new scoring system to predict the risk of postoperative acute renal failure in cardiac surgery].

Background: The aim of this study was to cross validate a new scoring system, based on preoperative risk factors, in predicting the risk of postoperative dialysis after cardiac surgery and recently proposed by Thakar et al.

Methods: Between January 2003 and March 2006, 1642 consecutive patients underwent cardiac surgery. From our clinical database, using Thakar's method, we calculated the total score for each patient.
