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.
