(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.
