- Close a hole in the urethra through which urine leaks out.
- Build up the thickness of the wall of the urethra so it seals tightly when you hold back urine.
Most bulking materials are injected around the urethra just outside the muscle of the urethra at the bladder outlet. Injecting the bulking material may be done through the skin, through the urethra or, in women, through the vagina. Needle placement is guided by the use of a cystoscope inserted into the urethra.
Urethral bulking procedures are usually done under local anesthesia in women, but men may require a general or regional anesthesia. A local anesthetic allows the person to stand up after an injection to find out if continence has been achieved. If continence has not been restored, another injection may be done immediately.
This treatment may help, but over time the effect wears off. It is common to need more treatments.
The surgery is used mostly for women and sometimes for men.
Some of the cost of this treatment may not be covered by your provincial health insurance.
What To Expect After Surgery
Most urethral bulking injections can be done in a doctor's office or surgery centre. They rarely require a hospital stay. You may need to take it easy for a few days afterward.
Why It Is Done
Urethral bulking may be done to treat:
How Well It Works
Urethral bulking may work for some women. But fewer than 4 out of 10 women have long-term benefits.footnote 1
The main risks related to urethral bulking are pain at the injection site, injury to the urethra, and migration of the bulking material.
What To Think About
This surgery is used mostly for women and sometimes for men.
This treatment method avoids the risks associated with abdominal surgery.
Before having urethral bulking treatment, ask your doctor about the following:
- How much success has the doctor had in treating incontinence with surgery? The success of surgical procedures for urinary incontinence depends on the experience and skill of the surgeon.
- Is there anything I can do to increase the likelihood of a successful surgery? Losing weight, quitting smoking, or doing pelvic floor (Kegel) exercises before surgery may increase the likelihood of regaining continence after surgery.
