[Renal arterial disease-induced tubulo-interstitial lesions].
Renal arterial disease-induced tubulo-interstitial lesions described in this chapter include benign arterio- and/or arteriolo-sclerotic and malignant nephrosclerosis, renal infarction and renal cortical necrosis. In these conditions renal glomeruli as well as tubules are always involved, and consequent loss of nephrons, or renal parenchyma results in interstitial fibrotic changes. The parenchymal lesions have a spectrum from slowly progressive atrophy and loss to necrosis of abrupt onset and disappearance of glomeruli and tubules. As for glomerular reactions to the ischemia, the intermediate type consisted of mesangial degeneration and epithelial cell proliferation described as "alterative glomerulitis" is noteworthy. Briefly, in renal arterial diseases, glomeruli are rather variably involved than tubules and loss of the parenchyma results in interstitial fibrosis.
