Should living kidney donors with hypertension be considered for organ donation?

Area of Science:

• Nephrology
• Transplant Surgery
• Hypertension Management

Background:

• Long waiting lists for kidney transplants necessitate exploring alternative donor pools.
• Living kidney donation can reduce transplant delays.
• Hypertension is increasingly considered as a criterion for living kidney donation.

Purpose of the Study:

• To evaluate the safety and outcomes of living kidney donation in individuals with hypertension.
• To assess the long-term renal health and blood pressure control in hypertensive kidney donors post-nephrectomy.

Main Methods:

• Review of existing studies on hypertensive kidney donors.
• Analysis of donor follow-up data, focusing on kidney function and blood pressure control.
• Comparison of outcomes between hypertensive and non-hypertensive kidney donors.

Main Results:

• Hypertensive kidney donors, particularly those over 50, exhibit favorable follow-up outcomes.
• Well-controlled hypertension (BP <140/90 mmHg) on limited medication is key.
• Selected donors (older, non-obese, no end-organ damage) fare as well as normotensive donors.

Conclusions:

• Short-term data suggest nephrectomy is safe for hypertensive donors.
• No significant increase in kidney disease incidence or worsening hypertension control observed.
• Modest evidence supports the long-term safety, warranting further investigation.
