Purpose: There are many risk factors for postoperative acute kidney injury in liver transplantation. The aim of this study is to investigate the risk factors for postoperative acute kidney injury in living donor liver transplantation recipients. Methods: 220 living donor liver transplantation recipients were retrospectively evaluated in the study. According to the Kidney Disease Improving Global Outcomes Guidelines, acute kidney injury in postoperative day 7 was investigated for all patients. The patient’s demographic data, preoperative and intraoperative parameters, and outcomes were recorded. Results: Acute kidney injury was found in 27 (12.3%) recipients. In recipients with acute kidney injury, female population, model for end-stage liver disease score, norepinephrine requirement, duration of mean arterial pressure less than 60 mmHg, the usage of gelatin and erythrocyte suspension and blood loss were significantly higher than recipients with nonacute kidney injury (for all p<0.05). In multivariate analyses, the likelihood of acute kidney injury on postoperative day 7 were increased 2.8-fold (1.1-7.0), 2.7-fold (1.02-7.3), 3.4-fold (1.2-9.9) and 5.1-fold (1.7-15.0) by postoperative day 7, serum tacrolimus level ≥10.2 ng dL⁻¹, intraoperative blood loss ≥14.5 mL kg⁻¹, the usage of gelatin >5 mL kg⁻¹ and duration of MAP less than 60 mmHg ≥5.5 minutes respectively (for all p<0.05). Conclusions: In living donor liver transplantation recipients, serum tacrolimus levels, intraoperative blood loss, hypotension period and the usage of gelatin may be risk factors for acute kidney injury in the early postoperative period.
