Before surgery you will have a blood test to check your general health. You will also have a chance to discuss the surgery with a specialist nurse or a doctor. You will have a medical examination to make sure that you are fit enough to have an anaesthetic. You may be admitted to the surgical ward on the day of surgery, or the day before. The anaesthetist will talk to you about your operation and ask you to sign a consent form. You may also be asked by the research nurse for permission for blood samples and some of the tissue taken at the time of surgery to be kept and used for research. If you agree to this, you will be asked to sign a second consent form.
The operation
Many tumours in the bladder are the small papillary type. These can usually be removed very easily using a cystoscope. You will be given a general anaesthetic and a cystoscope will be inserted into the bladder. The tumour is snipped off at the stem and the area is burned (cauterised), using a mild electrical current to limit bleeding. This procedure is known as a transurethral resection of a bladder tumour (TURBT) and in this way several tumours can be treated at the same time, if necessary.
The operation usually takes from 20 minutes to an hour. Chemotherapy may be given into the bladder immediately after surgery.
After the operation
When you go back to the ward you will have a thin, flexible tube (a catheter) in your bladder, which drains your urine into a bag. It may make you feel as though you want to pass urine. Your urine will be bloodstained at first. Large bags of fluid may also be used to flush out the bladder continuously. This is to make sure that clots of blood do not form and block the urethra.
Once you are drinking normally and your urine looks clear, the catheter will be taken out. This is not painful but may feel a little uncomfortable. Once your catheter has been removed and your urine is no longer bloodstained, you will be allowed to go home. This is usually about 2–3 days after the operation.
Possible risks of surgery
Removing superficial bladder cancers is a safe procedure. However, it can have some risks. These are outlined below.
Urine infection 5–10 out of every 100 patients (5–10%) may get a urine infection. This may be while they are still in hospital or after they go home. Signs of an infection include: feeling cold, shivery, hot or sweaty; feeling generally ill; or your urine becoming smelly or cloudy. If you think you may have an infection, you can take a urine sample to your doctor for testing.
Bleeding for more than a few days occurs in up to 5 out of 100 patients (5%) and a blood transfusion may be needed. If the bleeding does not stop on its own, another operation to cauterize the bleeding area may need to be done under anaesthetic.
Damage to the bladder A hole may be made in the bladder during surgery. This happens in up to 5 out of 100 patients (5%). If this happens, you may need to have a catheter in the bladder for up to 10 days to allow the hole to heal. If the hole does not heal in that time, you may need to have an operation to seal it. This is done in an operation that involves making a cut in the abdomen. Your doctor or nurse will explain this procedure if it is needed.
After cystoscopy – follow-up
After this type of treatment, you will need to have regular follow-up cystoscopies. This is because the tumours will come back in between 5–7 out of every 10 people (50 – 70%). The cystoscopies are usually done every three to four months at first. Most follow-up cystoscopies are done in the outpatients department under local anaesthetic.
If the cancer comes back, the tumours can usually be surgically removed while they are still in the early stages. However, some people may also have chemotherapy or BCG given directly into the bladder.
