The bladder stores urine until you are ready to empty it. It swells into a round shape when it is full and gets smaller as it empties. A healthy bladder can hold up to 16 ounces (2 cups) of urine comfortably. How frequently it fills depends on how much excess water your body is trying to get rid of.
This means empty your bladder about 2 hrs before the exam time, then drink 32 oz of water over the next hour. Do not empty your bladder until the ultrasound technologist tells you. 4. Start earlier if you think you will be unable to drink the full amount.
