This study evaluates the effect of the low molecular weight dextrans as a perfusion solution on early graft function of twenty living donor kidneys. Ten kidneys were perfused with +4 degrees C Ringer lactate after nephrectomy while other ten with +4 degrees C Ringer lactate + 10% Dextran. Immediate and delayed kidney function, blood creatinine, postoperative hemodialysis requirement, Doppler US and renal scintigraphy, third month graft survival and number of removed grafts were examined postoperatively as well as kidney biopsies. No statistical difference was found between the groups regarding the post-transplant ATN period. But the microscopic examinations demonstrated less damage-more function in Ringer lactate+Dextran group compared to Ringer lactate alone.
