Background: The purpose of this study was to evaluate long-term outcomes in high risk renal transplant recipients over 60 years of age compared with those younger than 60 years of age.

Materials And Methods: We analyzed outcomes in 131 consecutive renal transplant recipients at our institution between November 2001 and December 2007. Primary outcomes included incidence of delayed graft function (DGF), acute rejection, graft survival, patient survival, and incidence of infections and neoplasms.

Several contrast agents have been approved in the United States for radiographic imaging purposes. Most of the older ionic, high-osmolar contrast agents are no longer used because of their side effect profile. Therefore, newer nonionic, low or iso-osmolar contrast agents have been widely accepted as an alternative due to their improved tolerability and safety.

Furthermore, their presence prior to cardiac transplantation has also been the subject of similarly conflicting reports.
