While ischemia of the kidney usually results from some disturbance of the general circulation, it is known to occur also in consequence of local interference in the renal circulation. This is frequently observed in cases of lead colic, during which contraction of the renal arteries occurs. It also takes place, according to Cohnheim, in puerperal eclampsia; and Leyden has demonstrated that renal ischemia is an occasional consequence of pregnancy. Morbid Anatomy.--Renal ischaemia ismanifested by pallor of the cortex; r.fter longer duration, when fatty degeneration has occurred, by a yellow color. At times this color is diffuse, involving the entire cortex, while at other times the yellow color is visible only in spots or streaks, indicating local degeneration. The medullary portion usually presents a marked contrast in color, since it is dark red or purple in consequence of venous congestion. Microscopically, there is observed fatty degeneration of the epithelium, especially in the convoluted tubules and the glomeruli. In ischarnia of high grade, the interstitial tissue of the kidney usually contains a number of white and red blood-corpuscles, though no vascular rupture can be detected. Symptoms and Course.--Ischtemia of the kidney is in most cases an accompaniment of general ischemia, which is indicated by constitutional symptoms. The only features directly connected with the kidney are oliguria, albuminuria, and the presence of hyaline casts in the sediment. It is usual to find in cases of cachexia from malaria or syphilis, from chlorosis, after profuse hemorrhage, etc., traces of albumen and a few hyaline casts. These latter are sometimes provided with fatty granules, oil-drops, or even disintegrated epithelial cells. If the conditio...
