Studies in renal preservation using a rat kidney transplant model: II. The effect of reflushing with citrate.
This study investigated the possible beneficial effects of reflushing renal grafts with isotonic citrate solution. Rat kidneys were initially flushed with isotonic citrate or with Hartmann's solutions at O C. After 2 hr, half the kidneys of each group were reflushed with isotonic citrate; 22 hr later, all kidneys were transplanted into rats of the same inbred strain. All animals receiving kidneys flushed with Hartmann's solution died, whereas reflushing such kidneys with isotonic citrate significantly ameliorated the deleterious effects of Hartmann's solution. All animals receiving citrate-flushed kidneys survived with relatively good renal function and morphology. However, reflushing itself is not a beneficial procedure and is only of value where an ineffective preserving solution has been used to flush the kidneys initially. There is evidence that some of the adverse effects of flushing develop in the renal medulla.
