During this outpatient procedure, your health care provider inserts a tiny wire through your urethra and into your bladder. Next, a dilator is passed over the wire. Dilators open, or enlarge, the urethral opening. Progressively larger dilators are used. Each is in place for just a few seconds. The dilators gradually increase the size of the urethral opening. Talk to your care team about how often you may need this procedure. Note: This treatment is a temporary fix. The scar tissue likely will return.
