[Risk Analysis of Acute Kidney Injury after Cardiac Surgery and Protective Effect by Less Invasive Surgery].

Objective: We aimed to determine the incidence and risk of acute kidney injury (AKI) in patients after cardiac surgery, and to assess the effects of less invasive cardiac surgery on the prevention of postoperative AKI.

Methods: We retrospectively analyzed perioperative parameters in patients who underwent cardiac surgery. Risk factors for AKI were determined using univariate and multiple logistic regression models.
