Long-term Survival and Evolution of the Kidney Function for Liver Transplant Patients Who Required Postoperative Dialysis

Patients who underwent orthotopic liver transplantation (OLT) frequently develop chronic kidney disease, with those who present postoperative acute kidney failure and require renal replacement therapy (RRT) at higher risk. The objective of the study was to assess the kidney function and long-term survival of patients who underwent OLT and required RRT during or in the immediate postoperative period. Medical records of OLT and postoperative RRT patients with over 6-month survival were reviewed between January 1, 2005, and December 31, 2015. A variance analysis was carried out for repeated measurements to compare the estimate glomerular filtration rate (eGFR) baseline with the different periods (statistical significance level P .05). Kaplan-Meier estimator was used to estimate the survival rate. Of 539 patients, 20 (3.7%) met the selection criteria. The basal eGFR at 6 months and 1, 3, 5, and 7 years was 93.41 ± 25, 78.28 ± 33, 73.06 ± 29, 65.96 ± 19, 79.81 ± 28, and 59.06 ± 24 mL/min/1.73 m
