Single-donor cold storage versus machine perfusion in cadaver kidney preservation.

Preservation of thirty-eight consecutive renal allograft donors was studied in a prospective, randomized protocol. Procurement was in-situ cooled, en-bloc nephrectomy accomplished by a single program. Nine pairs were deleted because of nonutilization of one kidney or change in mode of preservation. The remaining twenty nine pairs were implanted by twenty two institutions through usual organ sharing policies. Results showed that posttransplantation dialysis was required in 17% of machine-perfused and 63% of cold-stored allografts, which reached statistical significance (P less than 0.01). This increased number of dialyses in patients receiving the cold-stored kidneys offsets cost savings achieved through transporting cold stored allografts. This study shows machine-perfused renal allografts to be superior to paired, cold-stored allografts when analyzed with respect to early graft function.
