Background:
After cadaveric kidney transplantation, preservation-reperfusion damage results in glomerular and tubular proteinuria. There are no data on the time course of proteinuria after living-donor (LD) transplantation.
Methods:
In 10 patients receiving a kidney graft from an LD, the excretion of high molecular weight proteins (albumin, transferrin, and immunoglobulin G) and low molecular weight proteins (beta2-microglobulin and alpha1-microglobulin) was measured at various time points during the first 5 days after transplantation.
Results:
Immediately after restoration of the circulation, we observed a massive nonselective high molecular weight proteinuria, indicative of glomerular damage. This proteinuria rapidly decreased to slightly elevated values beyond 24 hr after transplantation. Low molecular weight proteinuria, reflecting tubular damage, was also prominent and remained grossly abnormal even at day 5.
Conclusion:
After LD transplantation, preservation-reperfusion injury causes massive proteinuria during the first 24 hr. Thereafter proteinuria rarely exceeds 1 g per day.
