What is Stress Incontinence?

Stress Incontinence is the leakage of urine usually caused by an increase in pressure in the abdomen (tummy) such as when coughing or sneezing- figure 1.

The weakness is usually caused by childbirth in the first instance when the pelvic floor muscles and ligaments are damaged. Further weakening occurs as one goes through the menopause because the quality of the supporting tissues deteriorates.

The pressure in the abdomen rises when one coughs, sneezes or even bends, turns or jumps and results in urine leakage. This can cause a lot of distress and can limit ones quality of life.

It must be understood that these operations will not cure all urinary symptoms. They will only cure urinary symptoms caused by a weakness in the urethra (urine pipe) and bladder neck. Many urinary symptoms will have other causes.

 

Alternative to Surgery?

Do Nothing- if the leakage is only very minimal and is not distressing then treatment is not necessarily needed.

Pelvic Floor Exercises (PFE). The pelvic floor muscle runs from the coccyx at the back to the pubic bone at the front and off to the sides. This muscle supports your pelvic organs (uterus and bladder) and your bowel. Any muscle in the body needs exercise to keep it strong so that it functions properly. This is more important if that muscle has been damaged. PFE can strengthen the pelvic floor and correct or reduce stress incontinence. PFE are best taught by an expert who is usually a Physiotherapist. These exercises have little or no risk and even if surgery is required at a later date, they will help your overall chance of becoming continent.

Devices-There are numerous devices which essentially aim to block the urethra. The devices are inserted either into the vagina or the urethra. They are not a cure but their aim is to keep you dry whilst in use, e.g. during ‘keep fit’ etc.

The Benefits of Stress Incontinence Surgery

80% of women are substantially improved.

This means you may get back to:-

  • Physical activity- running, dancing, gym etc
  • Horse riding
  • Gardening
  • Resume sexual relations if hindered beforehand

This also means you may have renewed confidence so that:-

  • You can e.g. go shopping etc without fear of leaking
  • You do not have to worry about damp patches on clothing, in the car etc
  • You do not have to worry about unpleasant odours.

General risks of Surgery?

Anaesthetic risk. This is very small unless you have specific medical problems. This will be discussed with you.

Haemorrhage. There is a risk of bleeding with any operation. The risk from blood loss is reduced by knowing your blood group beforehand and then having blood available to give to you if needed. It is rare that we have to transfuse patients after their operation.

Infection. There is a risk of infection at any of the wound sites and bladder. A significant infection is rare.

Deep Vein Thrombosis (DVT). This is a clot in the deep veins of the leg. The overall risk is at most 4-5% although the majority of these are without symptoms. Occasionally this clot can migrate to the lungs which can be serious and in rare circumstances it can be fatal (less than 1% of those who get a clot). DVT can occur more often with major operations around the pelvis and the risk increases with obesity, gross varicose veins, infection, immobility and other medical problems. The risk is significantly reduced by using special stockings and injections to thin the blood (heparin).

Specific Risks of this Surgery?

Failure: 20% of women do not gain benefit from the operation. The operation however can be repeated.

Voiding difficulty: Approximately 10% of women will have some difficulty in emptying their bladder in the short term and if this happens we may send you home with a catheter for up to a week. If you still have difficulty emptying your bladder after 10 days (3%), then the options will be either learning how to catheterise yourself (you may need to do that a few times a day after passing urine to get rid of any urine left behind in your bladder), or going back to theatre to have the tape cut. Once the tape is cut, you may re-develop incontinence but there is an option of having another tape at a later date. Some women may need to change position to satisfactorily empty their bladder.

Bladder overactivity: Any operation around the bladder has the potential for making the bladder overactive leading to symptoms such as urgency (needing to rush to the toilet) and frequency (needing to visit the toilet more often than normal).

Tape exposure and extrusion (10%): The vaginal area over the tape may not heal properly or get infected and therefore part of the tape may need excising. This may need a return to theatre and may result in the operation being ineffective. Alternatively an attempt to re-cover the tape can be made. Very rarely the tape might erode into the urethra or the bladder which would require an operation as well. The risk of exposure is increased by smoking and with certain diseases.

Pain on intercourse: This may arise form scar tissue in the vagina as a result of the incision.

Visceral Trauma: During the sub-urethral sling operations the needle used may traumatise the bladder, or urethra. If it is noticed after return from theatre to the ward it may necessitate going back to theatre for a general anaesthetic and an operation to repair the damaged organ

The Operation- The Tension- Free Vaginal Tape (TVT)

This operation involves inserting a synthetic tape through the vagina in order to sit like a hammock under the urethra and prevent it moving down when the intra-abdominal pressure increases to such as when coughing. It now has data to show that it gives comparable success rate to the above traditional operation (Colposuspenion) up to 11 years after the operation, whilst allowing patients to go home on the same day in most cases.

Its main drawback is a small risk of injury to the bladder, urethra or bowels; and an extremely low risk of damage to a major blood vessel which has resulted in a few deaths (out of greater than a million procedures). There is a small risk of voiding difficulty and a small risk of overactive bladder symptoms (urgency and frequency)

It can cause tape erosion and difficulty emptying the bladder (mentioned above).

After the Operation (post-operative care)?

After the operation you will be taken back to the ward, where the nurses will check your blood pressure, pulse and wound.

You may eat and drink immediately on return from theatre. A mild pain killer may be required.

Most women do not have a catheter and can go home once they have urinated satisfactorily and the amount of urine has been checked. Some women will return from theatre with a urethral catheter to drain the bladder. Once this is removed and they have emptied their bladder satisfactorily as above on two occasions they can go home.

You may be given injections to keep your blood thin and reduce the risk of blood clots normally once a day until you go home or longer in some cases.

The wound is not normally very painful but sometimes you may require tablets or injections for pain relief.

There will be slight vaginal bleeding like the end of a period after the operation. This may last for a few weeks.

At home after the Operation?

It is important to avoid straining particularly in the first weeks after surgery. Therefore, avoid constipation and heavy lifting.

After any operation you will feel tired and it is important to rest. It is also important not to take to your bed. Mobilisation is very important. Simply pottering around the house will use your leg muscles and reduce the risks of clots in the back of the legs (DVT) which can be very dangerous. Activity will also help to get air into your lungs and reduce infections.

You can do pelvic floor exercises but build these up very gently. If you do too much it will be uncomfortable.

It is advisable to have showers rather than baths for three weeks and to keep puncture wounds clean and dry. They heal in about five days and have a glue dressing.

Avoid constipation- drink plenty of water/juice, eat fruit and green vegetables esp broccoli, plenty of roughage e.g. bran/oats.

Do not use tampons, have intercourse or swim for 6 weeks otherwise you out yourself at risk of the tape eroding into the vagina.

There are stiches in the skin wound in the vagina. The surface knots of the stitches may appear on your underwear or pads after about two weeks, this is quite normal. There may be little bleeding again after about two weeks when the surface knots fall off, this is nothing to worry about.

At 2 weeks gradually build up your level of activity.

After 4-6 weeks, you should be able to return completely to your usual level of activity.

You should be able to return to a light job after about 3-4 weeks. Leave a very heavy or busy job until 6 weeks.

You can drive as soon as you can make an emergency stop without discomfort, but you must check this with your insurance company, as some of them insist that you should wait for six weeks.

In Summary

A TVT is a day case/overnight procedure for women who have stress incontinence and have not been helped with pelvic floor exercises. The operation will not help other urine symptoms and may even make some other urinary symptoms worse (urinary frequency and urgency).

It is successful in 8 out of 10 women. The tape used can cause pain and can erode into the vaginal skin.
