Urethral bulking involves the injection of a special material called a bulking agent. Your doctor can perform this minimally invasive procedure under local anesthesia in the office or an outpatient surgical center.
The bulking agent helps build up the thickness of the urethral wall to support the bladder and form a tight seal to prevent urine leakage. Using a periurethral or transurethral approach, your doctor will inject the bulking material into the area around the urethra.
