This has triggered interest in alternative storage methods, since marginal grafts especially tolerate cold storage poorly. The technique of normothermic ex vivo kidney perfusion (NEVKP) represents a novel preservation method for kidney grafts prior to transplantation.
Heterotopic Renal Autotransplantation in a Porcine Model: A Step-by-Step Protocol J. Moritz Kaths1,2, Juan Echeverri1,3, Nicolas Goldaracena1, Kristine S.

This article describes a heterotopic porcine renal autotransplantation model, which allows investigating new approaches to improve the outcome of transplantation using marginal kidney grafts.
