Lesión renal aguda en trasplante hepático ortotópico.

OBJECTIVES: To determine the incidence of acute kidney injury during the first 7 days post-orthotopic liver transplantation and to identify factors associated with acute kidney injury. MATERIALS AND METHODS: A retrospective, single-center analysis was conducted from 2018 to 2023, including patients undergoing liver transplantation. Preoperative, intraoperative, and postoperative variables were analyzed. Variables were evaluated in three multivariate linear regression models. A p value < 0.05 was considered statistically significant. RESULTS: A total of 45 patients were included from which 19 manifested acute kidney injury according to KDIGO criteria. In the preoperative univariate analysis, BUN, urea, MELD-Na score, intraoperative hypotension, time at Intensive Care Unit, and intrahospital stay days (6 vs 9) were statistically significantly associated with acute kidney injury. In the multivariate analysis, only preoperative MELD-Na score, intraoperative hypotension, and time at Intensive Care Unit remained statistically significantly associated with the development of acute kidney injury after orthotopic liver transplantation. CONCLUSIONS: The incidence of acute kidney injury after orthotopic liver transplantation was lower than previously reported in Mexico and in international studies. Similarly, the main factors associated with acute kidney injury after orthotopic liver transplantation were preoperative MELD-Na score, intraoperative hypotension, and time at intensive therapy.
