A variety of bulking agents, such as collagen and carbon spheres, are available for injection near the urinary sphincter. The doctor injects the bulking agent into tissues around the bladder neck and urethra to make the tissues thicker and close the bladder opening to reduce stress incontinence.
After using local anesthesia or sedation, a doctor can inject the material in about half an hour. Over time, the body may slowly eliminate certain bulking agents, so you will need repeat injections. Before you receive an injection, a doctor may perform a skin test to determine whether you could have an allergic reaction to the material.
Scientists are testing newer agents, including your own muscle cells, to see if they are effective in treating stress incontinence. Your doctor will discuss which bulking agent may be best for you.
