How is the Test Performed?
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. The choice of which scope to use depends on the purpose of the exam.
If the standard rigid cystoscope is used, you lie in the lithotomy position (on back with your knees up and apart). The flexible cystoscope may be easier to insert than the standard rigid model. It does not require the lithotomy position for insertion.
The procedure usually takes between 5 and 20 minutes. The urethra is cleansed and a local anesthetic is applied. The scope is then inserted through the urethra into the bladder.
Water or saline is inserted through the cystoscope and fills the bladder. As this occurs, you are asked to describe the feeling to your health care provider, which provides information about your condition.
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 of a need 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.
