Since initiation of model for end‐stage liver disease (MELD)‐based allocation for liver transplantation, the risk of posttransplant end‐stage renal disease (ESRD) has increased. Recent US data have demonstrated comparable, if not superior survival, among recipients of living donor liver transplants (LDLT) when compared to deceased donor liver transplant (DDLT) recipients. However, little is known about the incidence of ESRD post‐LDLT. We analyzed linked Scientific Registry of Transplant Recipients (SRTR) and US Renal Data System (USRDS) data of first‐time liver‐alone transplant recipients from February 27, 2002 to March 1, 2011, and restricted the cohort to recipients with a laboratory MELD score ≤25 not on dialysis prior to transplantation, in order to evaluate the incidence of ESRD post‐LDLT, and to compare the incidence among LDLT versus DDLT recipients. There were 28 707 DDLT and 1917 LDLT recipients included in the analyses. The 1‐, 3‐ and 5‐year unadjusted risk of ESRD was 1.7%, 2.9% and 3.4% in LDLT recipients, compared with 1.5%, 3.0% and 4.8% in DDLT recipients (p > 0.05), respectively. In multivariable competing risk Cox regression models, there was no association between receiving an LDLT and risk of ESRD (sub‐hazard ratio: 0.99, 95% CI: 0.77–1.26, p = 0.92). In conclusion, the incidence of ESRD post‐LDLT in the United States is low, and there are no significant differences among LDLT and DDLT recipients with MELD scores ≤25 at transplantation.
