Influence of warm and cold ischemia time on initial function and one-year survival of renal allografts.

The influence of the duration of warm and cold ischemia on initial graft function on patient survival, graft survival, and graft function one year after transplantation was assessed in 234 consecutive cadaveric renal transplants. The number of grafts with delayed function was found to increase with increasing duration of the warm and cold ischemia times. On the other hand, the duration of the ischemia times and consequently the initial function, whether immediate or delayed, did not influence the survival of graft and patient nor the function of the graft one year after transplantation.
