Chronic Pyelonephritis - (PH 1728) (pp. 699-701)
(Be able to identify this slide as end stage kidney; identify normal glomeruli, abnormal glomeruli, tubules, and fibrotic inflamed area; and differentiate between this slide and slides showing normal kidney.)

In chronic pyelonephritis, not only the tubules but also the glomeruli have been damaged. Some of the tubules are filled with casts, some of the glomeruli have become hyalinized (appear solid and pink) and there are scattered patches of white blood cells. Compare this slide with the slide of normal kidney and with Fig. 46-6, p. 700, Fig. 46-11, p. 706.
