Surgery
There are several different kinds of surgeries to correct
stress incontinence, which results when weakened
pelvic floor muscles allow the bladder neck and
urethra to drop. These surgeries seek to lift the
urethra and/or
bladder into the normal position. This makes sneezing,
coughing, and laughing less likely to make urine leak from the bladder.
Surgery is usually not done for
urge incontinence.
The decision to have surgery must always be based on an accurate
diagnosis, consideration of other treatment possibilities, and realistic
expectations for the surgery.
Surgery Choices
- Retropubic
suspension. The Marshall-Marchetti-Krantz (MMK) and Burch
colposuspension procedures are the most common types of retropubic suspension.
Retropubic surgeries provide lift to the sagging bladder neck and urethra by
attaching their supporting tissues to the pubic bone or tough ligaments. These
surgeries require hospitalization.
- Urethral sling.
The surgeon fashions a piece of muscle, ligament, or tendon tissue or synthetic
material into a sling that lifts the urethra back into a normal position. Since
this involves abdominal surgery, hospitalization is required.
- Tension-free vaginal tape (TVT) surgery. TVT surgery
is commonly used for stress incontinence. During this surgery, a mesh-like tape
is positioned under the urethra like a sling or a hammock to support it and
return it to its normal position. The surgeon inserts the tape through small
incisions in your vagina and pubic hair line. TVT surgery takes approximately
30 minutes and is usually done under
local anesthesia. This surgery can also be done to
correct incontinence that has come back after having another type of
incontinence surgery.
What To Think About
The Society of Obstetricians and Gynaecologists of Canada (SOGC)
recommends the Burch colposuspension procedure for urinary incontinence until
long-term research shows that TVT surgery works and is safe.9
The transobturator tape (TOT) surgery is like TVT surgery. But
because it is newer, experts can't yet say how safe and long-lasting it
is.2
Factors that may decrease the effectiveness of surgical treatment
include obesity, long-term (chronic) cough, radiation therapy, aging, low
estrogen level after menopause, poor nutrition, and strenuous physical
activity.
Most surgical failures are due to incorrect diagnosis. Other
reasons for failure include surgery that is not done well, healing problems,
obesity, and additional causes of incontinence that could not be identified
before correcting the primary cause.
