Renal Grand Rounds Winter 2017: Urea in the Treatment of Hyponatremia

Hyponatremia, defined as a plasma sodium (PNa) concentration less than 135 mEq/L, is the most common electrolyte disorder. Hyponatremia is associated with an increased risk of mortality in hospitalized patients. It has also recently been recognized that milder, and apparently asymptomatic, forms of hyponatremia are not only associated with increased mortality, but also with an increased risk of neurocognitive deficits, gait disturbances, falls, bone fractures, and osteoporosis. Hyponatremia also is associated with significant costs to our health care system.

Educational objectives:

Upon completion of this activity, participants should be able to:

  • Describe the mechanism(s) of action of urea in hyponatremia
  • Identify advantages of the use of urea in hyponatremia
