Histological and clinical evaluation of marginal donor kidneys before transplantation: Which is best?

Area of Science:

• Nephrology
• Transplantation Medicine
• Medical Diagnostics

Background:

• Organ shortage significantly limits kidney transplantation worldwide.
• Marginal donor kidneys (older, hypertensive, diabetic, non-heart-beating donors) are increasingly used but often have poorer outcomes.
• Accurate pre-transplant evaluation of these kidneys is essential to optimize recipient outcomes and resource allocation.

Purpose of the Study:

• To review the historical and current criteria for evaluating kidneys for transplantation.
• To examine the advantages and disadvantages of different evaluation methods.
• To discuss the limitations of existing criteria and the potential of novel technologies.

Main Methods:

• Review of existing literature on kidney donor evaluation criteria.
• Analysis of historical trends in the application of histological and clinical donor evaluation.
• Exploration of emerging technologies, including omics, for organ assessment.

Main Results:

• Pre-transplant histological and clinical donor evaluations have evolved over time, with varying emphasis on each.
• Current evaluation methods possess inherent limitations, leading to suboptimal organ utilization and potential risks.
• No single criterion has proven universally sufficient for evaluating marginal kidney quality.

Conclusions:

• Existing methods for evaluating marginal kidneys for transplantation are insufficient.
• There is a need for updated guidelines and improved assessment strategies.
• Omics technologies show promise for enhancing kidney organ evaluation and may lead to better transplantation outcomes.
