Transplantation of Kidneys After Normothermic Perfusion: A Single Centre Experience.

Abstract

In order to expand the pool of usable donors from circulatory death (DCD) there is increasing interest in normothermic regional perfusion (NRP) to assess and improve liver viability2. NRP may also improve outcomes in kidney transplantation. We present our single centre experience of outcomes in imported kidneys following NRP. Data was obtained from a prospectively maintained database between December 2012 and September 2018. Primary endpoints were incidence of delayed graft function (DGF) and estimated glomerular filtration rate (eGFR). 632 decease donor kidneys were transplanted, 229 from DCD donors, 29 of which had NRP. The DGF rate was lower for NRP vs DCD (6 of 29, 20.7% vs 70 of 200, 35.0%) with reduced duration of DGF. Multivariate analysis demonstrated transplant type to be a statistically significant independent predictor of eGFR at 7 and 14 days. Early transplant function in NRP kidneys was comparable to DBD. There were no graft losses within 30 days in the NRP group. One-year graft loss rate was 3.4% for NRP and 6.0% for standard DCD. This data suggests NRP is safe, and reduces rates of DGF and improves early renal function. This article is protected by copyright. All rights reserved.
