Proteinuria is common after kidney transplantation and typically urine protein levels are
below 500 mg/d. However, even these low levels are associated with reduced graft survival.
Most allografts with proteinuria> 1500 mg/d have new glomerular pathology. In contrast,
lower levels of proteinuria are generally associated with nonglomerular, nonspecific
histologic changes. The relationship between proteinuria and graft survival is independent
of other variables, including graft function and graft histology. Thus, proteinuria allows …
