WHAT IS A CYSTOSCOPY?
Cystoscopy is a test that allows specialists to look at the inside of the bladder and the urethra using a thin, lighted instrument called a cystoscope. The cystoscope is inserted into the urethra and slowly advanced into the bladder. This procedure allows specialists to look at areas of the bladder and urethra that usually do not show up well on X-rays. Tiny surgical instruments can be inserted through the cystoscope that allow specialists to remove samples of tissue (biopsy) or samples of urine.
