acute kidney failure
Definition
Noun: * Acute kidney failure: A sudden, often temporary, loss of kidney function where the kidneys rapidly lose their ability to filter waste products from the blood. This condition is typically associated with events like severe burns, physical trauma, acute infection, or obstruction of the urinary tract.
Usage
- This is a medical term used primarily in clinical and healthcare contexts.
- It describes a serious, rapid-onset condition, as opposed to chronic kidney failure, which develops slowly over time.
- It is often abbreviated as AKF or referred to as acute renal failure (ARF).
Examples
- The patient was admitted to the ICU with acute kidney failure following a severe septic infection.
- Dehydration and certain medications can be contributing factors to acute kidney failure.
- The doctor explained that the obstruction was causing acute kidney failure, which required immediate intervention.
Advanced Usage
- Clinical Stages: The condition is often described in stages based on severity, using criteria like the KDIGO (Kidney Disease: Improving Global Outcomes) guidelines.
- Etiology: It is commonly categorized by its cause: prerenal (reduced blood flow to kidneys), intrinsic (damage within the kidney), or postrenal (obstruction of urine flow).
