Carbamazepine-induced hyponatremia after transabdominal follicular ultrasound examination.
We report a serious complication after transabdominal follicular ultrasound monitoring in a patient taking CBZ for a chronic seizure disorder. She developed severe hyponatremia after a large volume of water intake for bladder filling before her scan. We recommend the use of transvaginal US scans in such patients or as an alternative to the transabdominal approach in all patients, since we have found good patient tolerance and excellent pelvic organ visualization without the need for bladder filling.
