Evaluation of Postoperative Acute Kidney Injury (AKI) Incidence and Risk Factors in Patients Underwent Pneumonectomy

Acute kidney injury (AKI) is a critical complication associated with a high incidence of morbidity and mortality that can occur in critically ill patients and after major surgical procedures. Although there is a decrease in pulmonary damage with restrictive fluid management and protective ventilatory strategies in patients who underwent wide lung resection to prevent pulmonary edema development after resection, the relative hypovolemia and hypoperfusion developed in patients may lead to renal dysfunction. The incidence of AKI after thoracic surgery can be up to 15% and is associated with prolonged length of stay (LOS) in hospital. The incidence of AKI is higher in patients with extensive resection such as pneumonectomy compared with lobectomy and wedge resection. Since AKI is not only a rare complication but also a risk factor for mortality, it is important to identify the incidence and risk factors of AKI, to prevent AKI and related complications and to improve patients outcomes. In this study incidence of AKI was defined using the KDIGO criteria according to the change of serum creatine levels.

166 patients who underwent pneumonectomy from January 2008 to December 2018 included the retrospective observational study. Demographic data, intraoperative data, rates of complications, risk factors for AKI, mortality, lenght of stay in intensive care unit (İCU) and hospital were evaluated. AKI was defined using the KDIGO criteria according to the serum creatinine levels. The SPSS 11.5 program was used for statistical analysis.
