What is the test?
Cystoscopy enables your
doctor to take a direct look inside your bladder through a small
camera inserted through the urethra. It is a common test used
to look for causes of bleeding in the urine and some other bladder
problems.

How do I prepare
for the test?
Tell your doctor ahead
of time if you have ever had an allergic reaction to lidocaine
or the numbing medicine used at the dentist's office.
If you take aspirin,
nonsteroidal anti-inflammatory drugs, or other medicines that
affect blood clotting, talk with your doctor. It may be necessary
to stop or adjust the dose of these medicines before your test.

What 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 discomfort.
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.

What risks are
there from the test?
Most patients will have
some burning or soreness in their urethra, penis, or vagina after
the test for a short time. It is common to see some blood in
the urine for 24 to 48 hours after the exam.

Must
I do anything special after the test is over?
You should call your
doctor if you have persistent bleeding, bleeding with clots,
or a fever after this test.

How
long is it before the result of the test is known?
Your doctor can tell
you what was seen inside your bladder right after the test. If
you have a biopsy sample taken, analysis will take several days.
