Successful transplant outcomes using pediatric en bloc kidneys into adult recipients.

En bloc pediatric kidneys have been used in adult renal transplantation for over 30 years. Despite the duration of this experience, issues such as increased technical difficulties and associated complications, hyperfiltration injury, and ultimately a limited allograft half-life have limited the use of these organs at many centers. To date, however, the collected experience suggests that these organs may in fact be an excellent source of allografts for adult transplantation. The present paper was a retrospective review of the experience using en bloc kidneys for adult transplantation from two institutions. These results support the use of these kidneys. Actual patient and graft survival at 2 years was 97% and 94% respectively.
