Kidney Failure After Living Kidney Donation in Australia: A National Registry Linkage Study, 2004-2024.

National linkage of the Australia and New Zealand Living Kidney Donor Registry and the Australia and New Zealand Dialysis and Transplant Registry provides the first Australian estimates of kidney failure treated with kidney replacement therapy (KRT) after living kidney donation (2004-2024). Out of 5291 donors (56,962 person-years; median follow-up, 10.96 years), three donors underwent KRT (0.53 per 10,000 person-years). No events occurred within 10 years of donation. Australian clinicians can now counsel and guide potential donors using local data: risk of kidney failure requiring KRT is very low, but late events warrant lifelong follow-up.
