Symptomatic Hyponatremia following Acute Urinary Retention

Background: Hyponatremia due to acute urinary retention is not a common condition. Moreover, symptomatic hyponatremia requires management with hypertonic saline and other supportive measures mostly in ICU settings. Case report: We report a case of symptomatic hyponatremia secondary to acute urinary retention probably due to release of vasopressin due to urinary bladder distension which was managed with urinary bladder catheterization and other supportive measures leading to resolution of hyponatremia. Conclusion: Acute urinary retention can lead to hyponatremia which may be corrected by treatment of the cause and other supportive measures.
