Abstract

Urine microscopy with examination of the urine sediment examination provides useful diagnostic information about the histology of the kidneys. While most nephrologists use urine microscopy to assess for the presence of glomerular diseases, they are less apt to use this diagnostic test when pre-renal acute kidney injury (AKI) or acute tubular necrosis (ATN) is clinically suspected. More often, tests such as fractional excretion of sodium (FeNa) and fractional excretion of urea (FeUrea) are used to differentiate these two causes of acute kidney injury.
