[Physiologic performance of clinically non-functioning kidney transplants].

The excretion capacity of 24 kidney allografts which had been dialyzed because of non-function was examined. It has been shown that only 4 out of 24 allografts (16.7%) were truly without function. All other transplants did show a slight or more improvement of the excretion capacity prior to irreversible loss of graft function. As a cause the non-identified graft rejection is discussed.
