Overview

Renal insufficiency may broadly be divided into two categories: Acute kidney injury vs. chronic kidney disease

Definition of Terms

Acute kidney injury (AKI)

Acute kidney injury (AKI), formerly known as acute renal failure, is characterized by an abrupt loss of kidney function resulting in a failure to excrete nitrogenous waste products (among others), and a disruption of fluid and electrolyte homeostasis. AKI is defined as any of the following:

  • Increase in serum creatinine concentration by 0.3 mg/dL in 48 hours
  • Increase in serum creatinine concentration by more than 50% of baseline or 1.5 times baseline concentration within the past 7 days
  • Decrease in urine volume <0.5 mL/kg/h for 6 or more hours

Chronic renal disease (CKD)

Chronic kidney disease (or chronic renal insufficiency) is a broad spectrum of disorders that disturb the structural or functional integrity of the kidney for more than 3 months. CKD is defined as any of the following:

  • Kidney damage for ≥ 3 months as defined by structural or functional abnormalities of the kidney, with or without decreased GFR, manifest by either pathological abnormalities or markers of kidney damage (including abnormalities in the composition of the blood or urine or imaging abnormalities)
  • GFR <60 mL/min/1.73 m2<M/sup> for ≥3 months with or without kidney damage

Acute-on-chronic renal failure (AoCRF)

Acute-on-chronic renal failure (AoCRF) is defined as the presence of acute kidney injury on top of chronic renal disease. AKI of AoCRF may be reversible, and the aim of treatment is to return the patient to baseline renal function prior to the acute insult.
