Risks and outcomes of living donation

Area of Science:

• Nephrology
• Transplantation Surgery
• Public Health

Background:

• Living donors provide 40% of US renal allografts.
• Donor nephrectomy has low perioperative mortality (3/10,000) and complication rates (3-6% major, 22% minor).
• Long-term mortality and ESRD risk are not increased in white donors post-nephrectomy.

Purpose of the Study:

• To assess the long-term risks of living kidney donation.
• To identify specific donor subgroups with potentially higher post-donation risks.
• To highlight the need for improved data collection and risk assessment methods for diverse living donors.

Main Methods:

• Analysis of existing data on perioperative outcomes.
• Identification of demographic factors associated with increased comorbidity risk.
• Discussion of limitations in current national donor follow-up data.

Main Results:

• Donor nephrectomy shows no increased long-term mortality or ESRD risk in white donors.
• Certain subgroups (e.g., African Americans, obese donors) may have higher risks for chronic renal failure, hypertension, and diabetes post-donation.
• The precise impact of uninephrectomy on lifetime risks in these subgroups remains undefined.

Conclusions:

• Accurate, comprehensive long-term risk assessment is crucial for living kidney donors, especially across diverse populations.
• Improved national data collection, focused studies, and database integration are needed.
• Continued efforts are vital to ensure informed consent and public trust in living donation programs.
