Acute (Hematogenous) Pyelonephritis - (PH 1726) (pp. 698-699)
(Be able to identify this slide as abnormal; identify normal glomeruli, tubules, and inflamed areas; and differentiate between this slide and slides showing normal kidney.) 

In pyelonephritis, infection of the kidney causes inflammation and damage to the tubules. Note the scattered patches of inflammatory white blood cells. Using high power, notice that the tubular cells have indistinct outlines because they are damaged. The glomeruli appear normal. Compare this slide with that of the normal kidney.
