Cystoscopy

Alternative names:

cystourethroscopy

How the test is performed:

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. If the standard rigid cystoscope is used, you lie in the lithotomy position (on back with your knees up and apart). The urethra is cleaned and a local anesthetic is applied. The scope is then inserted through the urethra into the bladder. The flexible cystoscope may be easier to insert than the standard rigid model. It does not require the lithotomy position for insertion. The choice of which scope to use depends on the purpose of the exam.

Water is inserted through the cystoscope and fills the bladder (you are asked to describe the feeling to your health care provider). As the water fills the bladder, it stretches the bladder wall, enabling the physician to view the entire bladder wall. You will feel the sensation 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.

The average cystoscopy takes about 15 to 20 minutes.

How to prepare for the test:

You must sign an informed consent. You will wear a hospital gown during the procedure. Make arrangements for travel home from the hospital.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:

• infant test or procedure preparation (birth to 1 year)
• toddler test or procedure preparation (1 to 3 years)
• preschooler test or procedure preparation (3 to 6 years)
• schoolage test or procedure preparation (6 to 12 years)
• adolescent test or procedure preparation (12 to 18 years)

How the test will feel:

There may be slight discomfort as the cystoscope is passed through the urethra into the bladder. You will feel uncomfortable (a strong need to urinate) when the fluid has filled the bladder. You may feel a pinch if a biopsy is taken. After the cystoscope is removed, the urethra may be sore and you will feel a burning sensation during urination for a day or two.

Why the test is performed:

• diagnose and evaluate urinary tract disorders
• check for cancer of the bladder or urethra
• diagnose an enlarged prostate (men)
• help determine the cause of pain during urination
• diagnose recurrent bladder infections
