Acute kidney injury

Defining prerenal azotemia in clinical practice and research

Nature Reviews Nephrology volume 6, pages 641642 (2010) | Download Citation

Prerenal azotemia is a common occurrence in hospitalized patients and is generally easier to define in clinical practice than in clinical research. Monitoring the duration of acute kidney injury and biomarkers of kidney function might help distinguish prerenal azotemia from acute tubular necrosis in both clinical practice and research settings.
