==Acute==
Acute renal failure is rapidly progressive but may be reversible. It can result from pre-renal, intra-renal or post-renal factors.
*Prerenal factors include ischaemia and reduced renal perfusion
*Intrarenal factors include acute interstitial nephritis and
*Postrenal factors include lower urinary tract obstruction.
Clinical signs include oliguria or anuria, [[Vomiting|vomiting]] and anorexia; blood sample analysis shows azotaemia.
