Some of these products absorb leaked urine and some put pressure on the urethra to help prevent urine from leaking.

Place a tube (catheter) into your bladder to prevent too much urine from building up.

The nerves and muscles work together to prevent urine from leaking out of the body.

Muscles surrounding the urethra (the tube that takes urine away from the bladder) have the job of keeping the passage closed, preventing urine from passing out of the body.

The muscles of the bladder and ureters, along with the pressure of urine in the bladder, prevent urine from flowing backward through the ureters.

These muscles are meant to prevent urine from leaving the body, but they may be "overridden" if the bladder has a strong contraction.

The external sphincter can be contracted voluntarily, which will prevent urine from passing down the urethra.

The end of the ureter is surrounded by bladder muscle in this new position in the bladder, which prevents urine from refluxing toward the kidneys.

This will prevent urine from accumulating in the bladder, which allows the injured bladder or urethra to heal.
