Kidney preservation: perfusion versus cold storage-1975.

Area of Science:

• Nephrology
• Transplant Surgery
• Organ Preservation

Background:

• Cadaver kidney preservation is critical for successful transplantation.
• Comparing preservation methods impacts organ viability and patient outcomes.

Purpose of the Study:

• To compare the efficacy of simple hypothermic preservation in Collins solution versus pulsatile perfusion for cadaver kidneys.
• To evaluate the impact of different preservation techniques on 1-year transplant survival rates.

Main Methods:

• Retrospective analysis of over 1000 kidney transplants performed between December 1973 and June 1975.
• Data collection on kidneys preserved using Collins solution, Belzer machine, Waters machine, and Sacks solution.
• Comparison of 1-year transplant survival rates across different preservation methods.

Main Results:

• Kidneys preserved in Collins solution showed a 1-year survival rate of 59% ± 5% (n=89), significantly better than pulsatile perfusion methods.
• Collins solution survival was superior to the Belzer machine (41% ± 3%, n=358; p=0.005) and Waters machine (47% ± 3%, n=421; p=0.05).
• Collins solution also outperformed cold storage in Sacks solution (34% ± 6%, n=97; p=0.005).

Conclusions:

• Simple hypothermic preservation with Collins solution is a more effective method for cadaver kidney preservation than pulsatile perfusion.
• The findings suggest Collins solution offers improved outcomes for kidney transplant recipients.
• Data from multiple centers and shared kidneys indicate the robustness of these findings.
