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.
If you are not sure how long your bladder takes to fill, experiment at home. Drink some water and time how long it takes before your bladder feels full, explains 101 Diagnostics. For abdominal ultrasounds, patients should cease eating about four hours before the appointment to obtain accurate readings.
