Abstract

The kidneys play a vital role in maintaining normal blood volume, acid-base, and electrolyte balance. Urine is easy to collect via free catch, catheterization, or cystocentesis and provides a window into renal handling of electrolytes and water. Rather than comparing urine electrolyte measurements to a list of reference ranges, urine biochemistry is best interpreted by evaluation of an individual's renal response to a specific abnormality and determination of whether or not that response is appropriate. In this way, urine biochemistry may provide valuable insight into the underlying pathophysiology and renal response to a variety of electrolyte disorders.
