in Renal Transplantation

Histidine-tryptophan-ketoglutarate (HTK) is replacing University of Wisconsin (UW) solution as the preser-vation fluid for renal allografts in many centers, but recent large-scale data to support this transition are lacking. We conducted a retrospective analysis of pa-tient and graft outcomes after renal transplantation at our center, comparing 475 consecutive living donor and 317 deceased donor transplants since the adoption of HTK with equal numbers of grafts preserved using UW solution. Data collected included donor and recip-ient age, race, sex, comorbidities and graft ischemia time. Graft and patient survival, as well as the inci-dence of delayed graft function (DGF), were studied by Kaplan–Meier and Cox regression analysis. No sig-nificant difference was seen in either patient or graft survival. Deceased donor kidneys in the HTK group had a higher incidence of DGF than the UW cohort, whereas this trend was reversed in the case of living donor organs. In multivariate analysis, HTK was asso-ciated with a significant risk reduction on the incidence of DGF. Prolonged preservation with HTK compared to UW was not associated with excess risk to the graft or patient. In summary, HTK demonstrated efficacy simi-lar to UW in terms of patient and graft survival
