Cystoscopy of the Bladder


Cystoscopy is a test that looks at the inner lining of the bladder and the tube from the bladder to the outside of the body (urethra). The cystoscope is a thin, lighted viewing tool that is put into the urethra and moved into the bladder.

When the cystoscope is inside your bladder, sterile water or saline is injected through the scope to help expand your bladder and to create a clear view. A medicine may also be injected through the scope to reduce chances of infection.

A cystoscopy can check for stones, tumors, bleeding, and infection. Cystoscopy can see areas of the bladder and urethra that usually do not show up well on X-rays. Tiny surgical instruments can be put through the cystoscope to remove samples of tissue (biopsy) or samples of urine.

Cystoscopy also can be used to treat some bladder problems, such as removing small bladder stones and some small growths.
