Abstract Background Patients undergoing liver transplantation (LT) are prone to dialysis‐requiring acute kidney injury (AKI‐D). However, long‐term prognoses among them need further investigation, as overall survival after LT is improving. Methods A nationwide, population‐based cohort study was conducted using the data of Korean National Health Insurance System between 2006 and 2015. The patients who received dialysis during the perioperative period of LT were in the AKI‐D group, and the control group included those who did not undergo dialysis. Results Among the 6879 patients who underwent LT, 968 were in the AKI‐D group. All‐cause mortality [adjusted hazard ratio (HR): 1.52 (1.26‐1.83), P < 0.001], end‐stage renal disease (ESRD) progression [adjusted HR: 2.93 (2.34‐3.66), P < 0.001], and ICU readmission [adjusted HR: 1.70 (1.44‐2.01), P < 0.001] within and after 90 days from discharge were increased in the AKI‐D group. When analyzed among those who recovered from dialysis at discharge, overall outcomes were similar to those of the AKI‐D group, except the long‐term mortality. Conclusions AKI‐D during the perioperative period of LT was associated with worse mortality, ESRD progression, and ICU readmission risk. The results of renal‐recovered patients could indicate clinicians that achievement of dialysis independence is important to gain favorable long‐term postdischarge survival.
