Definition    Return to top

Cystoscopy is a procedure to see the inside of the bladder and urethra.

How the Test is Performed    Return to top

Cystoscopy is performed with a cystoscope -- a specialized tube with a small camera on the end (endoscope). There are two types of cystoscopes:

The way the cystoscope is inserted varies, but the test is the same. Which cystoscope your doctor uses depends on the purpose of the exam.

If the standard rigid cystoscope is used, you will lie on your back with your knees up and apart. If a flexible cystoscope is used, this position will not be necessary.

The procedure usually takes 5 - 20 minutes. The urethra is cleansed. A local anesthetic is applied. The scope is then inserted through the urethra into the bladder.

Water or salt water (saline) is injected through the cystoscope to fill the bladder. As this occurs, you will be asked to describe the feeling. Your answer will reveal information about your condition.

As fluid fills the bladder, it stretches the bladder wall. This lets your health care provider see the entire bladder wall. You will feel the need to urinate when the bladder is full. However, it must remain full until the examination is complete.

If any tissue appears abnormal, a small sample can be taken (biopsy) through the cystoscope and sent to a lab for analysis.

How to Prepare for the Test    Return to top

You should make arrangements for someone to take you home from the hospital.

How the Test Will Feel    Return to top

You may feel slight discomfort when the cystoscope is passed through the urethra into the bladder. You will feel an uncomfortable, strong need to urinate when your bladder is full.

You may feel a quick pinch if a biopsy is taken. After the cystoscope is removed, the urethra may be sore. You may feel a burning sensation during urination for a day or two.

Why the Test is Performed    Return to top

Normal Results    Return to top

The bladder wall should appear smooth. The bladder should be normal size, shape, and position. There should be no obstructions, growths, or stones.

What Abnormal Results Mean    Return to top

Risks    Return to top

There is a slight risk of excessive bleeding when a biopsy is taken. There is also a risk that the bladder wall will rupture from the cystoscope or during biopsy.

Considerations    Return to top

You must be sure to drink 4 - 6 glasses of water per day after your cystoscopy.

You may notice a small amount of blood in your urine following this procedure. If the bleeding continues after you urinate 3 times, contact your health care provider.

Contact your health care provider if you develop any of these signs of infection:
