Abstract
The increasing waiting times for deceased donor kidneys have focused attention on living donors as a useful way to increase the organ supply. However, living donors with potential medical risks for renal transplantation raise medical and ethical questions for donor nephrectomy about conditions such as hypertension, hematuria, obesity, and old age. Data on the long-term risks of conditions are sparse and potential acceptance criteria are under development. Many older donors hope to donate to their offspring, despite the presence of elevated blood pressure. Transplant professionals have internal debates on these situations that require a well-defined scoring system for donating risk. This review summarizes the characteristics and risk of marginal living donors in renal transplantation and discusses strategies for overcoming the current limitation.
