Transobtuator Sling (TOT)
Urinary Incontinence in Women
[Selections from a The National Kidney and Urologic Diseases Information Clearinghouse article]
Millions of women experience involuntary loss of urine called urinary incontinence (UI). Some women may lose a few drops of urine while running or coughing. Others may feel a strong, sudden urge to urinate just before losing a large amount of urine. Many women experience both symptoms. UI can be slightly bothersome or totally debilitating. For some women, the risk of public embarrassment keeps them from enjoying many activities with their family and friends. Urine loss can also occur during sexual activity and cause tremendous emotional distress.
Incontinence occurs because of problems with muscles and nerves that help to hold or release urine. The body stores urine - water and wastes removed by the kidneys - in the bladder, a balloon-like organ. The bladder connects to the urethra, the tube through which urine leaves the body.
Surgery for Stress Incontinence
In some women, the bladder can move out of its normal position, especially following childbirth. Surgeons have developed different techniques for supporting the bladder back to its normal position. The three main types of surgery are retropubic suspension and two types of sling procedures.
Retropubic suspension uses surgical threads called sutures to support the bladder neck. The most common retropubic suspension procedure is called the Burch procedure. In this operation, the surgeon makes an incision in the abdomen a few inches below the navel and then secures the threads to strong ligaments within the pelvis to support the urethral sphincter. This common procedure is often done at the time of an abdominal procedure such as a hysterectomy.
Sling procedures are performed through a vaginal incision. The traditional sling procedure uses a strip of your own tissue called fascia to cradle the bladder neck. Some slings may consist of natural tissue or man-made material. The surgeon attaches both ends of the sling to the pubic bone or ties them in front of the abdomen just above the pubic bone.
Midurethral slings are newer procedures that you can have on an outpatient basis. These procedures use synthetic mesh materials that the surgeon places midway along the urethra. The two general types of midurethral slings are retropubic slings, such as the transvaginal tapes (TVT), and transobturator slings (TOT). The surgeon makes small incisions behind the pubic bone or just by the sides of the vaginal opening as well as a small incision in the vagina. The surgeon uses specially designed needles to position a synthetic tape under the urethra. The surgeon pulls the ends of the tape through the incisions and adjusts them to provide the right amount of support to the urethra.
If you have pelvic prolapse, your surgeon may recommend an anti-incontinence procedure with a prolapse repair and possibly a hysterectomy.
Recent women''s health studies performed with the Urinary Incontinence Treatment Network (UITN) compared the suspension and sling procedures and found that, 2 years after surgery, about two-thirds of women with a sling and about half of women with a suspension were cured of stress incontinence. Women with a sling, however, had more urinary tract infections, voiding problems, and urge incontinence than women with a suspension. Overall, 86 percent of women with a sling and 78 percent of women with a suspension said they were satisfied with their results. For more information, please visit www.uitn.net. Women who are interested in joining a study for urinary incontinence can go to www.ClinicalTrials.gov for a list of current studies recruiting patients.
Talk with your doctor about whether surgery will help your condition and what type of surgery is best for you. The procedure you choose may depend on your own preferences or on your surgeon''s experience. Ask what you should expect after the procedure. You may also wish to talk with someone who has recently had the procedure. Surgeons have described more than 200 procedures for stress incontinence, so no single surgery stands out as best.
