The fate of cadaver renal allografts contaminated before transplantation.

Through the routine use of cultures from saline slush transport solution and the initial and final organ perfusates, 14 of 81 cadaver allografts (17.3%) were found to have been contaminated before transplantation. Gram negative organisms, cultured from 5 of the 14 contaminated allografts, resulted in the recipient's death on the first encounter with this problem and the loss of two other allografts. Early antibiotic therapy begun even without evidence of overt infection appeared to prevent any further deaths or graft loss in those whose allografts were contaminated and yielded an overall survival comparable to that of uncontaminated allografts. Without such an approach to the study of perfused cadaver allografts and the management of them when found to be contaminated, this type of infection may go undetected and contribute to allograft and patient loss.
