Incontinence | Female | Slings

Description of Procedure

General Information

The female mid-urethral sling is a minimally invasive, outpatient procedure to treat stress urinary incontinence.  This surgery has been performed sing the mid 1990's and has been shown to be safe and effective. The sling lies under the urethra acting as a “hammock” which maintains urethral support and keeps it closed during abdominal pressure increases (as with a cough, sneeze, or athletic activity), preventing loss of urine.

The Procedure

The female sling is a short (15-30 minute) outpatient surgery done under general anesthesia, spinal anesthesia or under sedation with local anesthesia.  A 2-3 cm (1 inch) incision is made in the vagina as well as 2 mini incisions just above the pubic bone or in the inner thigh just beside the labia. In some cases only a single vaginal incision is made. The sling, made of surgical mesh (polypropylene), is then placed under the urethra and brought out through the mini incisions using specially designed instruments. The sling is then adjusted to the proper tension (no pressure on the urethra) and then buried under the skin incision after excess mesh is removed.  The incisions are closed with dissolvable sutures.  Patents usually go home within a few hours after surgery.

The Goals of Surgery

The primary aim is to improve the severity of stress urinary incontinence to a satisfactory level.  Most patients (90% or more) will achieve this goal.  Some of these patients (about 70-80%) are completely dry.  Please note that this surgery is not designed to treat overactive bladder or urge incontinence (see Incontinence Overview for more information about this).  In some cases of mixed incontinence, one may eperience an improvement in both stress and urge-related leakage events - usually these patients have a unique condition where the urge incontinence is triggered by stress incontinence episodes.

 

Potential Risks

In general, the rate of any serious complication is very low (less than 2% overall) making the risk-benefit profile of this surgery highly favorable.  Potential risks include:

  • Bleeding –  The chance of significant bleeding requiring hospitalization or blood transfusion is very low (less than 1 in 100).  After the procedure, you may experience bleeding similar to a light period for a day or two and may want to use a pad to protect your clothing. You should not have heavy vaginal bleeding or blood in the urine.
  • Infection – This risk is low and you will be given preventative antibiotics following the procedure.
  • Urinary retention – Almost all patients will go home after the surgery without a catheter.  It is not uncommon to feel some mild slowing in urination for a few days after surgery.  If you can’t void easily you may go home with a catheter for one or two days. In rare cases (less than 2%) a second procedure to loosen or cut the sling may be necessary.
  • Sling exposure in the vagina (vaginal erosion) – Rarely, the vaginal skin may not heal well and the underlying sling material may be exposed. This usually resolves with time and use of estrogen-type creams over the area.  Rarely, surgery is needed to remove the exposed sling.
  • Injury to the bladder or urethra (including ureethral erosion) – Cystoscopy is performed at the time of the procedure to visualize the bladder and urethra.  If bladder perforation occurs, it can almost always be corrected during the procedure and a catheter needs to remain in for about 7 days after surgery to let the bladder heal completely.
  • Hip and leg pain – This may occur with slings placed through the inner thigh technique.  The discomfort usually resolves over several days.
  • Urinary urgency/urge incontinence – A small number of women may have new onset urinary urgency following the sling procedure. This resolves in most cases, but in some medication or other therapies may be required.

What to Expect

  • You will begin a voiding trial immediately following surgery.  You should void every 2-3 hours.  If unable to void you should perform self-catheterization if you have been taught how.  Keep track of voided and/or catheterized volumes.  If you have not been taught self-catheterization and cannot void you will need to go to your nearest hospital emergency room for a catheter to be placed.

  • If you have an indwelling catheter please see catheter care instructions.

  • Urinary frequency, urgency and a slower urine stream may occur in the first 1-2 weeks.

  • Vaginal bleeding similar to a light period is expected for 1-2 weeks.

  • May experience pain or discomfort around incision sites.

  • You may experience inner thigh discomfort.

 

Cautions

Report any of the following to your doctor:

  • Heavy vaginal bleeding or clot passage.
  • Catheter blockage.
  • Bright red blood or clots in the urine.
  • Fever over 38.5 C.
  • Severe pain unrelieved by medication.

 

 

Diet

  • Clear liquid diet immediately after surgery.
  • Advance to usual diet as tolerated.

 

Activity

  • Get up and about as soon as possible after surgery.
  • Walk as tolerated.
  • Avoid lifting more than 30 lbs or vigorous physical activity for one month.
  • No intercourse or tampons for 6 weeks.
  • You may start showering 24-36 hrs after surgery.  Avoid water stream directly on
    incision.  You may sponge bathe.  Do not submerge in a tub bath for 3-4 weeks.
  • You may start driving about 5-10 days after surgery.  Do no drive if you are still on
    narcotic pain medication or have limited mobility.
  • Your return to work will be dependent on your job requirements.

 

Medications

  • Take antibiotics as per prescription.
  • Use prescription pain medication as needed.
  • Take a stool softener (obtain over the counter) starting the night of your surgery.  Stop
    taking stool softeners once having soft bowel movements.  Do not take stool softeners if
    diarrhea occurs.
  • If you have not had a bowel movement by the 3rd day after your surgery, take a laxative
    (obtain at your local pharmacy over the counter).
  • You may begin your regular medications when you leave the hospital unless instructed
    otherwise.
  • If you take bloodthinners (ASA, plavix, warfarin), your doctor will advise when you can
    start them again.
