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.
Normally, the bladder begins to fill with urine from the kidneys. The bladder stretches to allow more and more urine. You should feel the first urge to urinate when there is around 200 mL (just under 1 cup) of urine stored in your bladder.
