Pulsatile preservation (PP) of donor kidneys led to higher immediate function rates and shorter hospital stays compared to cold storage (CS). This kidney preservation method also reduced overall costs in transplant patients.

Area of Science:

  • Nephrology
  • Transplantation Surgery
  • Organ Preservation

Background:

  • Cadaveric kidney transplantation is a critical treatment for end-stage renal disease.
  • Optimizing organ preservation techniques is essential for improving transplant outcomes.
  • Traditional cold storage (CS) and newer pulsatile preservation (PP) methods are employed for donor kidney preservation.

Purpose of the Study:

  • To compare the efficacy of pulsatile preservation (PP) versus cold storage (CS) for cadaveric kidney transplants.
  • To evaluate the impact of preservation methods on immediate graft function, hospital stay, and costs.
  • To assess the long-term function of PP kidneys against their matched controls.

Main Methods:

  • A prospective study comparing 39 cold-stored (CS) kidneys with 35 pulsatile preserved (PP) kidneys over one year.

  • PP utilized the Water's Mox system with UW Machine Preservation Solution and vasodilators.
  • Kidney function was assessed for immediate function (IF) and compared with mate kidneys nationally.

    • Main Results:

    • Pulsatile preservation (PP) was associated with higher immediate function (IF) rates compared to cold storage (CS).
    • Kidneys preserved with PP experienced shorter hospital stays and decreased overall costs.
    • Comparison with mate kidneys confirmed higher immediate function rates for PP preserved organs.

    Conclusions:

    • Pulsatile preservation (PP) offers significant advantages over cold storage (CS) for cadaveric kidney transplantation.
    • PP improves early graft function, reduces healthcare resource utilization, and potentially lowers transplant costs.
    • The findings support the wider adoption of PP for kidney preservation, especially for marginal or imported organs.
