A flexible cystoscopy usually takes about five minutes.
Your doctor will pass the cystoscope into your urethra.
They will pass fluid through the cystoscope and into your bladder to help them make the diagnosis.
Your doctor will use the cystoscope to look for any problems in the lining of your bladder.
If they find a small growth or stone, it may be possible to remove it through the cystoscope.
