Clinical Trial Summary

Acute kidney injury (AKI) is a common complication during the early postoperative period after noncardiac surgery. Patients with AKI are at an increased risk of developing chronic kidney disease, prolonging hospitalization, and experiencing higher rates of morbidity and mortality. Identifying preoperative risk factors for postoperative AKI can significantly contribute to the development of preventive strategies and improved perioperative care in this vulnerable patient population. The goal of this retrospective study is to investigate the predictive value of preoperative inflammatory status, as measured by complete blood count-derived inflammatory markers, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), derived neutrophil-to-lymphocyte ratio (dNLR), neutrophil-to-lymphocyte*platelet ratio (NLPR), systemic immune-inflammatory index (SII), systemic inflammatory response index (SIRI), and aggregate index of systemic inflammation (AISI), on postoperative AKI in elderly patients undergoing non-cardiac surgery.
