Prognostic Significance of Preoperative Nutritional Status on Postoperative Acute Kidney Injury

The incidence of postoperative acute kidney injury (AKI) is high in patients undergoing lung resection surgery, especially in the elderly. Early identification of high-risk postoperative AKI patients can help develop prevention and treatment management strategies.

About this study

The goal of this retrospective study is to investigate the predictive value of preoperative nutritional status, as measured by three scoring systems - the geriatric nutritional risk index (GNRI), prognostic nutritional index (PNI), and controlling nutritional status (CONUT) score - on postoperative AKI in elderly patients under lung resection surgery.
