GFR Evaluation in Living Kidney Donor Candidates

Area of Science:

• Nephrology
• Transplantation
• Medical Guidelines

Background:

• Living kidney donation carries risks, including increased likelihood of kidney disease and failure post-donation.
• Recent data highlight the importance of evaluating long-term risks for donor candidates.
• The Kidney Disease Improving Global Outcomes (KDIGO) group has issued new recommendations for living donor evaluation.

Purpose of the Study:

• To review the rationale behind KDIGO's updated GFR recommendations for living kidney donor evaluation.
• To explain the principles of GFR measurement and estimation in donor assessment.
• To provide guidance on implementing the new GFR guidelines.

Main Methods:

• Review of KDIGO guideline recommendations concerning GFR in living kidney donors.
• Explanation of GFR measurement techniques (estimating equations, clearance measurements).
• Discussion of long-term risk assessment for end-stage renal disease (ESRD).

Main Results:

• KDIGO guidelines incorporate long-term ESRD risk into donor candidacy evaluation.
• Specific GFR thresholds are defined: ≥90 ml/min/1.73 m² for acceptance, <60 ml/min/1.73 m² for declination.
• An intermediate GFR range (60-89 ml/min/1.73 m²) requires consideration of additional factors.

Conclusions:

• Updated KDIGO guidelines provide a framework for GFR evaluation in living kidney donors, balancing donor safety and recipient needs.
• Standardized GFR assessment methods and risk stratification are crucial for informed donor selection.
• Implementation of these guidelines aims to improve long-term outcomes for kidney donors.
