    Abstract:
    The disparity between donors and the demand for organ transplants grows steadily. Annually, 4700 patients die on the kidney transplant waiting list in the United States. To increase utilization of deceased donor organs, we expanded our acceptable criteria to include very old (VO) or very young (VY) donors. We transplanted both such kidneys (dual transplant) into a single recipient and evaluated the long-term outcomes and complications. From July 2001 to December 2005, 16 patients (mean age 68, range 60-78) received dual kidneys from VO (mean age 72, range 60-79) donors and 6 patients (mean age 47, range 27-72) were transplanted from VY (mean age 17 months, range 2-36) donors. Seventy-four percent of these kidneys were imported after rejection by their local center due to low glomerular filtration rate (GFR) and extreme age. One- and 5-year patient survival rates were 100% and 88%, respectively. Death-censored 1- and 5-year graft survival rates for recipient of VO kidneys were 95% and 93%, and 66% and 50% for recipients of VY kidneys, respectively. Five-year graft survival rate for recipients of VO donor kidneys was 93% and was equal to the survival of standard deceased donor (SCD) kidney transplants (87%). The 5-year survival of dual transplants from VO donors was higher than expanded criteria deceased donor (ECD; P=.05). Over a mean follow-up of 66±28 months, rejection rates were 10%, not statistically different than other groups. Of 22 dual transplants, four patients experienced urinary tract infections; three developed incisional subcutaneous seromas, and there were more urinary leaks compared to SCD (13.6% vs 2%, P=.002). The average 1- and 5-year estimated GFR (Cockcroft-Gault) was 57.4 and 54.6 mL/min, respectively. When properly placed in a single patient, such marginal organs are a valuable resource that offer comparable outcomes to SCD transplants and superior outcomes to ECD organs.
