Acute renal failure is a rapid and sudden loss of kidney function, often caused by factors like dehydration or medication reactions. Chronic renal failure is a gradual and irreversible decline in kidney function over time, usually causing irreversible damage to the kidneys. Measurements of kidney function such as creatinine levels and glomerular filtration rate can help differentiate between the two conditions.

A recent acute cause like severe bleeding and hypovolaemia or acute urinary tract obstruction usually point to an acute type of renal failure. Chronic Diabetes or hypertension, poly-cystic kidney disease etc on the other hand makes the chronic renal failure more likely.

An ultrasound can be helpful, as a chronic renal disease can lead to a shrunken kidney. So the size of the kidney can be helpful.

Serial measurement of serum creatinine is the preferred measure, but generally if in doubt, it is better to treat as acute renal failure, which is usually reversible, as opposed to the chronic form which is not.

Other biochemical abnormalities like hyperphosphataemia, hyperkalemia and low erythropoetin can also favor the chronic form of renal failure, but are generally less reliable.

What is the difference between acute renal failure and chronic renal failure?

The difference between acute renal (kidney) failure and chronic kidney failure, is that acute is a sudden onset. Something like a medical condition, trama, or surgery can cause the failure within days or even hrs. Chrinic kidney failure is slow damage to the kidney over a few years, resulting in the kidneys not being able to filter blood properly.

Acute means "now", "immediate", "current". Acute is often found as a description of a medical problem. For example, "The patient was admitted for acute renal failure." If the condition is not acute, it it chronic. For example, "The patient received a diagnosis of chronic renal failure."
