a kidney in which there is sclerosis of the arterioles, i.e., arteriolar nephrosclerosis resulting from long-standing benign hypertension. Such kidney’s tend to be pale red-brown or relatively gray, moderately reduced in size, and firmer than normal organs; the capsular surfaces are uniformly finely granular. Most of the arterioles are thickened and hyalinized, thereby resulting in varying degrees of narrowing of the lumens, ischemia, and fibrosis in the interstitial tissue, leading to uniform contraction of the cortex.
