[Comparative study of the University of Wisconsin solution versus Eurocollins in kidney transplant]

Abstract

UW (University of Wisconsin) solution, formulated by Belzer's team in Madison, has already been proved to increase cold ischemia time in liver and pancreas preservation. A multicentre clinical trial is being conducted to compare renal preservation in human transplantation using two different solutions: UW and Eurocollins (EC). This paper, whose results will be included in the multicentre trial, reports local comparative results between UW and EC perfused Kidneys. The two donor populations UW (28 cases) and EC (47 cases) were not randomized. They were however comparable in renal function prior to harvesting but not in age (35 +/- 13.4 years EC versus 27.7 +/- 12.4 years UW). The two recipient populations (48 EC versus 48 UW) were more homogeneous. Comparative results were significant with better graft function in the UW group: creatinine at one week: 499.2 +/- 296.3 EC versus 277.6 +/- 226.2 mumol/l, p less than 0.0001; creatinine at one month: 228.7 +/- 135 EC versus 159.7 +/- 135.6 mumol/l, p less than 0.02 and a decrease in acute tubular necrosis (39.5% EC versus 14.5% UW) and hospital stay. These results justify the use of UW solution by intraaortic flush especially during multi-organ procurement.
