[Morphology of the juxtaglomerular apparatus of allotransplanted human cadaver kidneys in the late periods following transplantation].

Histological structure of 13 allografted human cadaver kidneys was observed at late stages after transplantation (from 121 days to 3 years and 10 months). In the grafted kidneys with a well-preserved structure the microscopic picture of the juxtaglomerular apparatus (JGA) failed to differ significantly from the JGA in the control. This conclusion was confirmed by the karyometric data and by the results of the juxtaglomerular index calculation. In the allografted kidneys with severe destructive and dystrophic alterations there can occur a partial or complete JGA involution.
