Abstract

Current kidney exchanges such as the OPTN Kidney Paired Donation (KPD) program allow candidates to list multiple willing donors, but only one will donate if the candidate is matched. There are cases where multiple donors would be willing to donate if it resulted in their intended candidate being transplanted. This report studies the effects of having two donors donate in such cases.
