Abstract
Acute renal failure is associated with increased mortality in critically ill patients. Doppler ultrasound of the kidney holds promise as a novel form of monitoring renal perfusion. Measures of venous congestion may indicate when fluid is becoming harmful, while the assessment of renal arterial flow may help detect early acute renal injury.
