Live kidney donors (LKD) have significantly expanded the supply of critical organs. Of paramount importance of course has always been donor safety. A significant amount of time goes into the screening and evaluation of live donor candidates. As a result, candidates are known to be healthy at the time of donation. Following donation, however, there is less known about outcome. Historically, there has been no nationalized, systematic mechanism for following LKD. What is known to date is the result of largely single-center, retrospective studies. There is a documented incidence of kidney failure and proteinuria and increased prevalence of HTN. There are no longitudinal studies of the effect of kidney donation on blood pressure. Ambulatory blood pressure monitoring allows a unique opportunity to examine the effects of live kidney donation on the blood pressure profiles of LKD.
