Early detection of renal damage and disease in dogs and cats

Renal damage and disease can be caused by acute or chronic insults to the kidney. Acute renal damage often results from ischemic or toxic insults and usually affects the tubular portion of the nephron. In contrast, chronic renal disease can be caused by diseases and/or disorders that affect any portion of the nephron, including its blood supply and supporting interstitium. Early detection of acute renal disease facilitates appropriate intervention that can arrest or at least attenuate tubular cell damage and the development of established acute renal failure. Similarly, early detection of chronic renal disease, before the onset of renal azotemia and chronic renal failure, should facilitate appropriate intervention that stabilizes renal function or at least slows its progressive decline.
