chronic pyelonephritis

Last reviewed 01/2018

Chronic pyelonephritis (CPN) is a tubulo-interstitial disease, which is characterised by:

  • tubular damage
  • interstitial inflammatory changes
  • renal scarring

In contrast to all other tubulo-interstitial diseases (except analgesic nephropathy) there is also involvement of the renal pelvis and the calyces.
