Flexible cystoscopy

A flexible cystoscopy is a telescopic examination of the lower urinary tract using a fiberoptic telescope. The test is used primarily to diagnose bladder conditions, exclude cancer and assess anatomy prior to other surgeries. It allows for the prostate and its size to be assessed as well as to check for any strictures or narrowing along the urethra.

You will be awake for the inspection which takes approximately 3-8 minutes and is painless, although you may experience some discomfort.

There is no need for any special preparation for the test and no fasting is required. It is not necessary to cease any blood thinners and you are able to drive home afterwards. There is the option of using Entonox (happy gas) during the procedure to reduce discomfort but this won’t affect your driving.

A local anaesthetic gel is instilled into the urethra to help make the test as comfortable as possible and the flexible cystoscope is inserted into your urethra and passed into the bladder. Once the cystoscope is in place, your bladder will be emptied and partly filled with sterile water to allow the doctor to fully inspect all the bladder lining.

After the procedure you will need to pass urine to empty the water inserted during the procedure, you may experience some discomfort but this should pass. You will need to drink lots of fluids for the rest of the day.
