Introduction:

Recent studies have shown that maintaining kidney viability with expanded criteria during preservation is a challenge. The hypothermic infusion machine aims to mitigate the effect of cold storage on the quality of the organ when the time of cold ischemia is prolonged or the donor is suboptimal.

Objective:

To evaluate the complications presented by renal transplanted patients with cold static preservation or hypothermic pulsatile perfusion.

Material and Method:

Retrospective observational study during 2010-2012, including all kidney transplant patients in a third level hospital. The study variables: length of stay, hours of ischemia, need for dialysis and number of post-transplant sessions and the storage device, age and pathologies associated with the donor.

Results:

175 transplants were performed, 70 of which were donors ≥65 years old. 30 kidneys were perfused in a machine and static preservation was used in 40. Our findings regarding the use of the infusion machine lead to a decrease in the average length of stay and a reduced need for post-transplant hemodialysis.

Conclusions:

Due to the high percentage of organs difficult to preserve and from elderly donors, it is essential to seek continuous intravascular perfusion techniques for a more effective preservation of the organ.
