Organ preservation: experience with University of Wisconsin solution and plans for the future.
Transplantation of organs continues to be a primary therapeutic modality for treatment of end-stage organ disease, and 1-year graft survival rates show increasing improvements for most organs.  A number of transplant centers show 1-yr graft survival rates approaching 90% or more for the kidney, liver and pancreas.  Rejection continues to be the major cause for loss of organs and there is still a major shortage of organs for transplantation.  Additionally, many organs showed delayed graft function (or primary nonfunction) which may be related to either donor factors or preservation factors.  The University of Wisconsin solution for organ preservation has increased the safe time of preservation for the liver, kidney, and pancreas and helped to increase the quality and number of organs available for transplantation. However, the long-range goal of organ preservation (unlimited preservation) is still far from being reached.  In the past, preservation could accurately be categorized as an art and preservation solutions were developed based upon theoretical rationales about the mechanisms of organ injury at hypothermia and what agents would suppress injury.  The utility and success of this approach is exemplified by the developments of Collins solution and the UW solution.  However, further developments in methods to increase the quality and duration of preservation of all transplantable organs would appear to be dependent upon defining, systematically, how organs are injured and what can be done to suppress the injury.(ABSTRACT TRUNCATED AT 250 WORDS)
