Acute on chronic pyelonephritis with numerous septic foci present in an already scarred kidney

Acute on chronic pyelonephritis with numerous septic foci present in an already scarred kidney.


Acute pyelonephritis there is a diffuse interstitial infiltrate with polymorphonuclear leukocytes

Acute pyelonephritis. There is a diffuse interstitial infiltrate with polymorphonuclear leukocytes.

A board unshaped scar of healed pyelonephritis

B. Healed pyelonephritis associated with vesicoureteral reflux has produced scarring of both poles of the kidney with calyceal distortion due to infection of the peripheral compound papillae.
