Hypothermic machine perfusion in kidney transplantation.

Area of Science:

• Nephrology
• Transplantation Surgery
• Biomedical Engineering

Background:

• Hypothermic machine perfusion (HMP) is increasingly recognized for its potential in kidney preservation.
• There is a paradigm shift towards not only preserving but also enhancing graft function and predicting viability using HMP.
• Marginal quality kidneys, particularly from extended criteria donors, can benefit significantly from advanced preservation techniques.

Purpose of the Study:

• To summarize recent advancements in hypothermic machine perfusion (HMP) for kidney preservation.
• To highlight the evolving role of HMP in improving graft function and predicting viability.
• To discuss key areas of research including perfusion solutions, temperature, duration, and biomarkers.

Main Methods:

• Review of current literature on hypothermic machine perfusion for kidney transplantation.
• Analysis of novel developments in HMP technology and perfusion solutions.
• Investigation of methods for assessing graft viability during HMP, including perfusate biomarkers and perfusion dynamics.

Main Results:

• HMP demonstrates significant benefits for kidney preservation, especially for extended criteria donor grafts.
• Ongoing research focuses on optimizing HMP variables like duration, machine settings, and perfusion solution additives.
• Development of perfusate biomarkers and machine perfusion parameters is crucial for predicting post-transplant graft function.

Conclusions:

• Hypothermic machine perfusion is a valuable tool for preserving kidneys from deceased donors.
• Further research into HMP parameters and viability assessment methods is essential for improving transplant outcomes.
• HMP offers a platform for pre-transplant graft assessment, potentially aiding in donor kidney selection.
