What is a cystoscopy?

A cystoscopy is a medical procedure. It involves a doctor using a small camera to look inside your bladder.

It is important in diagnosing conditions that affect the bladder and urinary system.

Why a cystoscopy?

A cystoscopy allows a doctor to see inside your bladder. It is often recommended for people who have blood in their urine. It can also be used to find and treat bladder cancer and bladder stones.

Cystoscopy preparation

Your preparation for a cystoscopy depends on the type of anaesthetic being used.

If you are going to have a general anaesthetic you must stop eating and drinking several hours before the procedure.

If you are going to have a spinal anaesthetic (an epidural) you must stop eating and drinking several hours before the procedure.

If you are having a local anaesthetic you can eat and drink as usual.

Ask your doctor about medications. You might need to stop taking medicines such as aspirin for a few days before the procedure.

What happens during the procedure?

A cystoscopy is usually an outpatient procedure. You will be able to go home the same day.

During the cystoscopy, a thin tube with a camera and a light on the end (a cystoscope) is inserted into the tube that carries urine out of your body (the urethra). It is moved into your bladder. Your urologist can then see images of the inside of your bladder on a screen.

  • A flexible cystoscope will be used if the specialist only needs to look inside your bladder. You will probably receive a local anaesthetic gel or spray to numb the area.
  • A rigid cystoscope will be used to take a sample of bladder tissue or treat the area by passing small surgical instruments down the tube. In this case you will probably have a general anaesthetic or an epidural (spinal anaesthetic).

A cystoscopy can be uncomfortable, but it is usually not painful.

Care after a cystoscopy

You might feel tired and sick after a cystoscopy. You might feel some pain in your groin.

You might also feel a burning sensation when you pass urine. You might see some blood in your urine. This will clear up within a few days.

Potential risks, complications and when to seek help

Serious complications after a cystoscopy are rare.

Some people, men in particular, experience ongoing problems passing urine.

It is common to bleed for a few days after a cystoscopy. Bleeding persists very rarely. But it could be a sign of bladder damage.

There is also a small risk of developing a urinary tract infection. This can affect your urethra, bladder or kidneys.

If you experience any side effects, such problems with bleeding or passing urine or develop a fever, it is important to see your doctor as soon as possible.
