Successful renal transplantation depends on the modification of the normal immunologic response. The earliest attempts at such modification involved the use of ionizing irradiation. The significant morbidity and mortality of total body irradiation led to its abandonment in favor of the safer technique of local graft irradiation. While still commonly used, the efficacy of this technique has never been evaluated in a prospective, randomized fashion. The present study is a prospective, randomized, double blind evaluation of the efficacy of the addition of local graft irradiation to our immunosuppressive protocol. One hundred consecutive cadaveric renal transplants were randomized to receive either conventional immunosuppression alone or conventional immunosuppression plus local graft irradiation delivered in doses of 150 rads on the 1st, 3rd and 5th post-operative days. Patients were followed for a period of 2 years. No significant difference was demonstrated between the groups among any measured parameter. In conclusion, the addition of local graft irradiation in doses of 150 rads on d1, 3, and 5 does not appear to offer any advantage over standard immunosuppressive therapy and its use cannot be recommended.
