1Department of Internal Medicine, University Hospital of Zürich, Zürich, Switzerland.
Abstract:
An elderly man was hospitalized after a fall following an episode of dizziness. During the initial examination, he was found to have a distended bladder, caused by urinary retention. Moreover, he was diagnosed with severe hypoosmotic hyponatremia. After the urinary retention was resolved, the patient developed severe diuresis, and the hyponatremia corrected rapidly and spontaneously.
Learning Points:
Hyponatremia is a common affliction in the elderly population, with diverse causes, some of which are still not well understood.In cases of hyponatremia, urinary retention should be considered a possible cause.
