Pathogenesis

Etiology

  • Acquired (most common) due to microbes, drugs, toxins, etc.
  • Inherited.

Predisposing factors

General
  • Breed.

Pathophysiology

  • Acquiredpolycystic kidney disease → substantial tubulointerstitial inflammation and/or fibrosis → chronic renal failure.
  • Inheritedpolycystic kidney disease → cysts gradually enlarge → displace normal renal parenchyma → chronic renal failure.
  • Acquired and hereditary- cysts may be incidental finding, if only a small portion of renal tissue is affected.

Timecourse

  • Weeks to months.
