Late failure in cadaveric renal allografts.

Sixteen patients with renal cadaveric allografts who have survived for one year or longer are reported. The patients were analyzed from the standpoint of incidence, quantity and course of proteinuria in relation to renal function and the nature of the original disease.This analysis shows that proteinuria is progressive and is accompanied by a decline in renal function when the original disease is of an immune nature. This was not so in patients with non-immune original disease. These findings suggest that recurrence of original disease plays an important role in late failure of cadaveric renal allografts.
