Morphology of intrarenal arteries in transplants and in diseased kidneys of patients treated by long-term dialysis.

Intimal fibrosis of intrarenal arteries is rarely found in diseased kidneys of patients not treated by dialysis, but it is common and intensive in cases subjected to this therapy as well as in renal transplants. In this paper the incidence rate and morphology of this lesion are presented in 10 renal grafts and 13 kidneys of patients treated by chronic dialyses. The factors influencing the appearance of intimal fibrosis are discussed.
