Abstract:
:Based upon encouraging experimental results, we began employing a synthetic perfusate for cadaver kidney preservation. The new perfusate contains hydroxyethyl starch (HES) as the sole colloid for oncotic support; 107 cadaver kidneys were preserved and transplanted (93 primary, 14 nonprimary) using the HES solution and were compared with our previous experience of 180 cadaver kidneys (161 primary, 19 nonprimary) preserved and transplanted utilizing an albumin-based perfusate. All cadaver kidneys were locally harvested and preserved by machine perfusion. Donor and preservation characteristics in the HES (n = 61) and the albumin (n = 101) groups were comparable, with a mean preservation time of 30.9 hr. Cold storage in combination with hypothermic pulsatile perfusion (HPP) preservation was performed more often in the HES group (68.2% vs. 31.1%, P less than 0.001). Recipient characteristics were also comparable, and all received quadruple immunosuppressive therapy with sequential/Minnesota antilymphoblast globulin/(MALG)/cyclosporine. After primary transplantation, the incidence of immediate function (82.6% vs. 89.2%), preservation-related dialysis (14.9% vs. 8.6%), and primary nonfunction (2.5% vs. 0) were similar between the 2 groups, with trends favoring the latter HES data. One-month serum creatinine (1.8 vs. 1.7 mg/dl) and graft survival (95% vs. 97.8%) also were comparable. Similar trends were present in the retransplant group, including a significantly lower 1-month serum creatinine in the HES group (2.2 vs. 1.5 mg/dl; P less than 0.05). The preservation-related dialysis rate did not differ between primary and nonprimary transplants. Primary nonfunction has not occurred with our new perfusate. Combined cold-storage-HPP preservation with HES perfusate offers advantages over standard retrieval technology and provides excellent immediate allograft function.
