Abstract

The main cause of delayed renal function following the transplant of donor kidneys is ischemic induced acute tubular necrosis (ATN). The ability to determine the degree of ATN suffered by donor kidneys prior to their transplant would enable transplant surgeons to use kidneys that might otherwise be discarded and better predict post-transplant renal function. Currently, there are no reliable tests to determine the extent of ATN of donor kidneys prior to their transplant. In ongoing clinical trials, we have been using optical coherence tomography (OCT) to non-invasively image the superficial proximal tubules of human donor kidneys prior to and following transplant, and correlate these observations with post-transplant renal function. Thus far we have studied over 40 living donor kidneys and 10 cadaver donor kidneys, and demonstrated that this imaging can be performed in a sterile and expeditious fashion in the operating room (OR). Because of many variables associated with a diverse population of donors/recipients and transplant operation parameters, more transplant data must be collected prior to drawing definite conclusions. Nevertheless, our observations have thus far mirrored our previously published laboratory results indicating that damage to the kidney proximal tubules as indicated by tubule swelling is a good measure of post-transplant ATN and delayed graft function. We conclude that OCT is a useful procedure for analyzing human donor kidneys.
