Abstract:Hyponatraemia is frequently seen in the emergency department, possibly caused by the syndrome of inappropriate antidiuresis (SIAD). We report three cases in which we believe urinary retention with bladder distention caused hyponatraemia. Laboratory findings fulfilled the criteria for SIAD, for which no cause was found. Possibly pain or sympathetic nerve system activation leads to SIAD. Brisk diuresis occurred after placement of an indwelling urinary catheter with overly correction of sodium for which treatment… Show more
“…The differential diagnosis of the hyponatremia was hypocortisolism or syndrome of inappropriate antidiuretic hormone (ADH) secretion due to bladder distension. In both cases, overcorrection of hyponatremia could be treated with desmopressin [ 3 ]. However, both diagnoses could be rejected.…”
