About

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.

Full description

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.

Enrollment: 1,880 estimated patients

Sex: All

Ages: 65 to 100 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. aged ≥ 65 years
2. lung resection surgery including：pneumonectomy , bilobectomy , lobectomy, segmentectomy, wedge resection/bullectomy.

Exclusion criteria

1. patients with an American Society of Anesthesiologists (ASA) physical status V.
2. those with end-stage renal disease (i.e. a glomerular filtration rate of 15 mL/min/1.73 m2 or receiving haemodialysis).
3. those did not have sufficient data required for nutritional evaluation or AKI evaluation.
