In this prospective randomized trial a porcine model of renal autotransplantation was used to compare quality of preservation, as reflected by detailed analysis of posttransplant renal function, following 24-hr cold storage in phosphate-buffered sucrose (PBS140), hyperosmolar citrate (HOC), and University of Wisconsin (UW) preservation solutions. There were 6 deaths with primary nonfunction: 3 of 5 HOC, 2 of 5 UW, but only 1 of 5 PBS140. Analysis of the whole group and separate analysis of the survivors demonstrated significantly better renal function following preservation with PBS140 when compared with both HOC and UW, with a lower peak serum creatinine (P = 0.02) and improved loop of Henle function (P = 0.02). The animals in the PBS140 group also demonstrated a more rapid return to normal creatinine, higher GFR, improved tubular function, and higher effective renal plasma flow, with figures approaching statistical significance (P = 0.06-0.07). The proposal of UW as a universal storage medium prompted this study, and its results suggest the need for a clinical comparison of renal preservation using UW and PBS140 in a prospective randomized trial.
