There are two types of cystoscopes, the standard rigid cystoscope and the flexible cystoscope. The method for insertion of the cystoscope varies, but the test is the same. If the standard rigid cystoscope is used, you lie in the lithotomy position (on back with your knees up and apart).
The urethra is cleansed and a local anesthetic is applied. The scope is then inserted through the urethra into the bladder. The flexible cystoscope may be easier to insert than the standard rigid model. It does not require the lithotomy position for insertion. The choice of which scope to use depends on the purpose of the exam.
Water or saline is inserted through the cystoscope and fills the bladder (you are asked to describe the feeling to your health care provider).
As the fluid fills the bladder, it stretches the bladder wall, enabling the physician to view the entire bladder wall. You will feel the sensation to urinate when the bladder is full; however, it needs to remain full until the examination is complete.
If any tissue appears abnormal, a small specimen can be taken (biopsy) through the cystoscope to be analyzed.
The average cystoscopy takes about 15 to 20 minutes.
