Acute Kidney Injury

Start Here
Overview     

  • Acute kidney injury or AKI (in its worst form known as acute renal failure  or ARF)), is a serious form of kidney failure which usually comes on suddenly and which is often triggered by a particular event or "insult" to the kidneys.

  • AKI is difficult to treat but in some cases the cat may make a full recovery. In other cases, the cat will be left with residual kidney damage.

  • It is possible to have AKI and CKD simultaneously.

     
What is Acute Kidney Injury?
     
                 
Acute kidney injury (AKI) is a serious and usually severe form of kidney failure. Unlike CKD, which is chronic and usually develops gradually, AKI usually comes on suddenly and is often triggered by a particular event or "insult" to the kidneys.

Cats with AKI usually have very high bloodwork numbers. If a young previously healthy cat presents with high kidney values, AKI should always be considered.

Cats with CKD may develop AKI on top of the existing CKD, see below.

There is currently some debate over whether early CKD might actually be a slower and less abrupt version of acute kidney injury, according to Is progressive chronic kidney disease a slow acute kidney injury? (2016) Cowgill LD, Polzin DJ, Elliott J, Nabity MB, Segev G, Grauer GF, Brown S, Langston C & van Dongen AM Veterinary Clinics of North America Small Animal Practice 46(6) pp995-1013, which says "chronic kidney disease Stage 1 and acute kidney injury Grade I categorizations of kidney disease are often confused or ignored because patients are nonazotemic and generally asymptomatic. Recent evidence suggests these seemingly disparate conditions may be mechanistically linked and interrelated."

Pet Place has helpful information about acute kidney injury in layman's language.

Pathophysiology of acute kidney injury (2012) Basile DP, Anderson MD & Sutton TA Comprehensive Physiology 2(2) pp1303–1353 explains more about acute kidney injury in humans.

TREATING YOUR CAT WITHOUT VETERINARY ADVICE CAN BE EXTREMELY DANGEROUS.

I have tried very hard to ensure that the information provided in this website is accurate, but I am NOT a vet, just an ordinary person who has lived through CKD with three cats. This website is for educational purposes only, and is not intended to be used to diagnose or treat any cat. Before trying any of the treatments described herein, you MUST consult a qualified veterinarian and obtain professional advice on the correct regimen for your cat and his or her particular requirements; and you should only use any treatments described here with the full knowledge and approval of your vet. No responsibility can be accepted.
 
If your cat appears to be in pain or distress, do not waste time on the internet, contact your vet immediately.
