Definition
Acute (over hours and days) deterioration of kidney function. This measured by serum urea and creatinine, often accompanied by oliguria and anuria.
Epidemiology
Pathophysiology
There are lots of causes of acute renal failure:
- Hypovolaemia
- Sepsis
- Reduced cardiac output
- Obstruction
- Others: hepatorenal syndrome, vasculitis
Risk Factors
Clinical Features
Very much depends on cause but oliguria and anuria are both signs of acute renal failure.
Investigations
- U+E - creatinine and urea, particularly creatinine clearance. However, it can be an inaccurate measure of GFR. Also keep an eye out for any electrolyte disturbance.
