Mortality prediction in patients with acute kidney injury requiring renal replacement therapy after cardiac surgery.

Background And Objective: Acute kidney injury (AKI) is a common and potentially serious postoperative complication after cardiac surgery, and it remains a cause of major morbidity and mortality. The aim of our study was to assess the prognostic illness severity score and to estimate the significant risk factors for poor outcome of patients with AKI requiring renal replacement therapy (RRT) after cardiac surgery.

Materials And Methods: We retrospectively analyzed data of adult (>18 years) patients (n=111) who underwent open heart surgery and had developed AKI with need for RRT.
