AN UNUSUAL COMPLICATION FOLLOWING UROFLOWMETRY - WATER-INTOXICATION RESULTING IN HYPONATREMIA AND SEIZURE

Uroflowmetry is considered a simple and noninvasive test in the evalua tion of urinary symptoms. It requires patients to consume fluid orally for a full bladder prior to undertaking the test. Guidelines regardin g the amount and rate of oral fluid intake have not been accurately de fined. We report on a patient who suffered a serious complication of w ater intoxication with hyponatremia and seizure due to excessive water consumption and absorption during uroflowmetry. We discuss the underl ying factors concerning this complication and recommend a more conserv ative approach to attain a full bladder in a certain subgroup of patie nts at risk of developing such a complication.
