Cystoscopy and hydrodistension of the bladder

Q 1. What does the procedure involve?

A. This procedure involves telescopic inspection of the bladder, over distension of the bladder and possible bladder biopsy or removal of abnormal areas using heat diathermy.

Q 2. What are the alternatives to this procedure?

A. The alternatives include:

  • Various medications taken orally or instilled into bladder
  • Augmentation (enlargement) of the bladder with intestine

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. Either a full general anaesthetic (where you will be asleep throughout the procedure) or a spinal anaesthetic (where you are awake but unable to feel anything from the waist down) will be used. All methods minimise pain; your anaesthetist will explain the pros and cons of each type of anaesthetic to you.

You will usually be given injectable antibiotics before the procedure, after checking for any allergies.

A telescope is inserted through the water pipe (urethra) to inspect both the urethra itself and the whole lining of the bladder.

The capacity of the bladder when full is measured and the bladder is then stretched gently with fluid, under slight pressure, to increase its capacity.

Q 5. What happens immediately after the procedure?

A. A catheter will normally be inserted into the bladder after this. Once your urine is clear, the catheter will be removed. You will normally be allowed home once you have passed urine satisfactorily.

Q 6. What is the duration of stay?

A. The average hospital stay is one day.

Q 7. What are the side-effects or complications?

A. 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)

  • Mild burning or bleeding on passing urine for a short period after the operation
  • Temporary insertion of a catheter
  • Often a biopsy of the bladder may need to be performed at the same time

Occasional (between one in 10 and one in 50)

  • Infection of the bladder requiring antibiotics
  • There is no guarantee of relief of bladder symptoms
  • Permission for telescopic removal/ biopsy of bladder abnormality/stone if found

Rare (less than one in 50)

  • Delayed bleeding requiring removal of clots or further surgery
  • Injury to the urethra causing delayed scar formation
  • Perforation of the bladder requiring a temporary urinary catheter or return to theatre for open surgical repair

Q 8. What should I expect when I get home?

A. When you leave hospital, you will be given a discharge summary of your admission. This holds important information about your inpatient stay and your operation.

When you get home, you should drink twice as much fluid as you would normally for the next 24 to 48 hours to flush your system through. You may find that, when you first pass urine, it stings or burns slightly and it may be lightly bloodstained.

Q 9. What else should I look out for?

A. If you develop a fever, severe pain on passing urine, inability to pass urine or worsening bleeding, you should contact your urologist immediately.

Q 10. What are other important points?

A. A follow up appointment will be arranged following discharge at 1 week and then between six and 12 weeks after the operation. You may be asked to complete a frequency volume chart on arrival in the clinic, to assess the effects of the surgery.
