Why hydrodistention with cystoscopy is done

This procedure is done to figure out the cause of bladder pain. It may help diagnose bladder pain syndrome (BPS), also called interstitial cystitis (IC). If you have this health problem, you may feel pain when your bladder fills with urine. You may also need to pass urine more often.

This procedure is also sometimes done to treat BPS. It may be tried if other treatments, such as medicine, don’t work.

How hydrodistention with cystoscopy is done

This may be done in a hospital or at an outpatient facility. During the procedure:

• You are given medicine so you won’t feel any pain. It may also make you fall asleep.

• Your healthcare provider puts the cystoscope into your urethra. They gently move it forward into your bladder.

• Using the cystoscope, they slowly fill up your bladder with as much water as possible. This helps find out how much fluid your bladder can hold. 

• Your bladder is then drained and filled again.

• Your healthcare provider may look at your bladder lining with the cystoscope. They will see if there are any sores or other possible causes for your symptoms.

• Your bladder is drained.
