The transplant center is obligated to follow you at 6 months, 1 year and 2 years after surgery so that this information can be transferred to OPTN/UNOS. I hope one day that a donor registry can be documented. If you are having trouble contacting your center, call an administrator or patient liason, the social worker or living donor advocate. If not, call UNOS or OPTN, (there is a number or hotline for donors to call for complaints) or the National Kidney Foundation. The NKF has a new group formed called Living Donor Executive Committee and they may be able to help you. Donors really need to push for their follow up as it is so important that our data be collected so that the statistics can be updated and studied.
