Artificial Urinary Sphincter

Q 1. What does the procedure involve?

A. The artificial urinary sphincter consists of three components. One part is a circular cuff that is placed around the waterpipe (urethra). This cuff is connected to a small pump that sits in the scrotum and also connected to small fluid filled balloon that sits in the abdominal wall.

Q 2. What are the alternatives to this procedure?

A. the alternatives include:

  • Incontinence into a pad
  • Urethral catheter
  • Male sling.

Q 3. What should I expect before the procedure?

A. If you are taking blood thinning medication on a regular basis, you must discuss this with your urologist because these drugs can cause increased bleeding after surgery. There may be a balance of risk where stopping them will reduce the chances of bleeding but this can result in increased clotting, which may also carry a risk to your health. This will, therefore, need careful discussion with regard to risks and benefits. Aspirin does not usually need to be stopped but will be the decision of your surgeon.

You will usually be admitted on the same day as your surgery, or a day before. You will normally undergo pre assessment on the day of your clinic. After admission, you will be seen by members of the medical team which may include the consultant, junior urology doctors and nurse.

You will be asked not to eat or drink for six hours before surgery and, immediately before the operation, you may be given a pre-medication by the anaesthetist which will make you dry-mouthed and pleasantly sleepy.

Please be sure to inform your urologist in advance of your surgery if you have any of the following:

  • Co-morbidities like Diabetes, Hypertension, Coronary artery disease or, stroke, epilepsy
  • Any transmissible disease like HIV/AIDS, Hepatitis B or C etc
  • Presence of implants, pacemakers, graft etc
  • You are taking prescription drugs like-
    • Blood thinners/ anti-platelets i.e. Warfarin, ecosprin, clopidogrel etc
    • Anti-epileptics like phenytoin, valproate etc

Q 4. What happens during the procedure?

A. Normally, a full general anaesthetic will be used and you will be asleep throughout the procedure. In some patients, the anaesthetist may also use an epidural anaesthetic which improves or minimises pain post operatively.

You will have a small incision in the area between the scrotum and anus (the perineum) and the cuff will be placed around the waterpipe. A separate incision will be made in the groin. Through this second wound, the pump will be placed in the scrotum and the balloon placed in the abdominal wall.

Q 5. What happens immediately after the procedure?

A. You will be given fluids to drink from an early stage after the operation and you will be encouraged to mobilise as soon as you are comfortable to prevent blood clots forming in your legs. You will be given intravenous antibiotics through your vein (intravenous). You will usually be discharged the next day after your surgery.

Q 6. Are there any side effects?

Most procedures have a potential for side effects. You should be reassured that, although all these complications are well recognised, the majority of patients do not suffer any problems after a urological procedure.

Common (greater than one in 10)

  • Blood in the urine, and temporary stinging when you urinate after the procedure
  • In the long term, mechanical failure of the device

Occasional (between one in 10 and one in 50)

  • Urine infection
  • Wound infection
  • Temporary insertion of a bladder catheter
  • Later failure of the device as the cuff becomes lose around the waterpipe (urethral atrophy)
  • In the long term, infection of the device requiring removal

Rare (less than one in 50)

  • Erosion of the waterpipe through the waterpipe (urethra)

Q 7. What should I expect when I get home?

A. The device will be deactivated when you are discharged. You will be reviewed in clinic or on the ward at six weeks post discharge when the device will be activated (by pressing a button on the pump within the scrotum).

Q 8. What else should I look out for?

A. Men who undergo surgery in the perineum (between the anus and the scrotum) may find it easier to sit with your weight shifted onto your one of your buttocks.

You may find it more comfortable to sit using an air-filled donut, soft cushion or another type of pillow, especially for the first four weeks after surgery.

Any activity that requires you to straddle anything, such as riding a bicycle, motorcycle or a horse should be avoided for four to six weeks.

Q 9. Are there any other important points?

A. You will be reviewed in outpatients to see how you have got on. It is likely you will be asked to complete a questionnaire on your symptoms.
