Preoperative geriatric nutritional risk index and neutrophil-to- lymphocyte ratio relate to postoperative acute kidney injury in elderly patients undergoing laparoscopic abdominal surgery

Background: Acute kidney injury (AKI) poses a significant concern in elderly patients undergoing laparo- scopic abdominal surgery due to increased vulnerability arising from aging, comorbidities, and surgery-related factors. Early detection and intervention are crucial for mitigating short- and long-term consequences. This study aims to investigate the correlation between preoperative Geriatric Nutritional Risk Index (GNRI), neu- trophil-to-lymphocyte ratio (NLR), and the occurrence of...
