[Pathology of the transplanted kidney and basic renal disease of the recipient].

Among 359 kidney transplantations performed from 1976 to 1986 at Rostock the 4 most frequent original renal diseases were glomerulonephritis (280 x), pyelonephritis (74 x), diabetic nephropathy (22 x) and polycystic kidney disease (14 x). From 225 transplant kidneys in 284 cases pathomorphological examinations were performed (104 biopsies, 138 removed grafts, 42 postmortem transplant examinations). The most striking finding was the earlier occurrence of rejection in grafts from recipients with glomerulonephritis compared with pyelonephritis. Therefore, a more rapid and intense immune reaction could suggested in patients with glomerulonephritis as original renal disease.
