The urinary bladder and urethra uses a sphincter. A sphincter is a tight band of muscular tissue that acts like a "door". The door is designed to only open under certain circumstances. For humans, this means we hold our urine until we find a toilet. Then, the sphincter opens and urine flows out.

There can be problems with the sphincter, including being young. As young children, we learn over time to interpret the urge signal from our bodies, and to stop our activities and find a bathroom. Even children in grade school can still have occasional accidents. The key is to STOP whatever you are doing, and go to the bathroom.


Women who have had one or more children, or who have had repeated bladder/urethral infections can also find they have more bladder irritability and the sphincter does not close as well as in younger ages. Talk to your doctor.
