happens when the test is performed?
- You wear a hospital
gown for the test and lie on your back on a table with your
knees bent and your feet in footrests. The opening to your
urethra (at the end of the penis or the outside of the vagina)
and the skin around it is cleaned with soap. Most patients
then have a squirt or two of a jelly-like numbing medicine
pushed inside the opening of the urethra with a plastic syringe.
This makes it possible to insert the camera without causing
A tubular instrument called a cystoscope, which is about the
width of a pencil, is pushed inside the urethra and moved forward
until its end is inside the bladder. Clear fluid (saltwater)
is pumped through this tube into your bladder to expand it, so
that your doctor can see the inside of the bladder clearly. You
may feel some fullness from this fluid and experience the urge
to urinate. There is a small light and a very small camera on
the end of the cystoscope, which enable your doctor to view the
inside of your bladder on a TV screen. The end of the scope can
be moved in different directions with remote control, to show
all parts of the bladder.
The test takes about five minutes from the time that the camera
is inserted. Then the camera is pulled out and you are free to
use the bathroom.
If you are going to have a biopsy done during this test, you
might require some additional anesthesia. Your doctor will discuss
your need for a biopsy with you before the test.
