Cystoscopy
Cystoscopy is a surgical procedure. This is done to see the inside of the bladder and urethra using a thin, lighted tube.
How the Test is Performed
Cystoscopy is done with a cystoscope. This is a special tube with a small camera on the end (endoscope). There are two types of cystoscopes:
- Standard, rigid cystoscope
- Flexible cystoscope
The tube can be inserted in different ways. However, the test is the same either way. The type of cystoscope your doctor (urologist) will use depends on the purpose of the exam.
The procedure will take about 5 to 20 minutes. The urethra is cleansed. A numbing medicine is applied to the skin lining the inside of the urethra. This is done without needles. The scope is then inserted through the urethra into the bladder.
Water or salt water (saline) flows through the tube to fill the bladder. As this occurs, you may be asked to describe the feeling. Your answer will give some information about your condition.
As fluid fills the bladder, it stretches the bladder wall. This lets your doctor see the entire bladder wall. You will feel the need to urinate when the bladder is full. However, the bladder must stay full until the exam is finished.
If any tissue looks abnormal, a small sample can be taken (biopsy) through the tube. This sample will be sent to a lab to be tested.
Biopsy
A biopsy is the removal of a small piece of tissue for laboratory examination.

Ask your doctor if you should stop taking any medicines that could thin your blood.
The procedure may be done under anesthesia in a hospital or surgery center. In that case, you will need to have someone take you home afterward.
How the Test will Feel
You may feel slight discomfort when the tube 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 tube is removed, the urethra may be sore. You may have blood in the urine and a burning sensation during urination for a day or two.
Why the Test is Performed
The test is done to:
- Check for cancer of the bladder or urethra
Cancer
Cancer is the uncontrolled growth of abnormal cells in the body. Cancerous cells are also called malignant cells.
