Despite extensive efforts in the fields of donor selection and management, standardisation of organ retrieval procedures, storage solutions, and novel immunosuppressive protocols, the rates of delayed graft function (DGF) after renal transplantation have been stagnating between 30% and 50%. As DGF exerts negative influences on acute rejection episodes and long-term organ function, the early phase of transplantation immediately following reperfusion deserves special interest. Several studies on machine-controlled reperfusion showed promising results in various organs, in experimental and clinical settings. Moreover, the flushing of organs with Carolina rinse solution (CR) immediately prior to reperfusion has been proven beneficial and is being clinically applied in human liver transplantation in recognised departments. In our study, we set up an autogenic porcine kidney transplantation model and assessed the normal values (control group) for creatinine clearance (ClCr) and urine output per hour (U/h) after "standard" reperfusion similar to clinical transplantation. Subsequently, kidneys of the experimental group 1 were reperfused at a blood pressure (RR) under the systemic level by means of a roller pump. Group 2 kidneys were rinsed with CR before controlled reperfusion, analogous to group 1. Both groups were compared with each other and with the assessed normal values. Our findings for Group 1 are that pressure-reduced reperfusion negatively affected immediate graft function. ClCr was reduced from 9.9 (control group) to 3.4 ml/min, U/h from 233 to 132 ml ( P<0.05). Group 2 showed that rinsing the kidneys with CR before reperfusion improved functional parameters highly significantly, compared with group 1 (ClCr: 13.5 vs 3.4 ml/min, U/h: 384 vs 132 ml; P<0.05) and even showed a positive trend compared with the control group (ClCr: 13.5 vs 9.9 ml/min, U/h: 384 vs 233 ml; P=0.0546). We can conclude that in a model of porcine renal autotransplantation, pressure-reduced reperfusion via a roller pump is detrimental to early kidney graft function. The flushing of organs with CR prior to controlled reperfusion significantly improves ClCr as well as urine output.
