Bladder biopsy

Alternative names:

biopsy of the bladder

How the test is performed:

A bladder biopsy is usually performed as a part of a cystoscopy. If abnormalities of the bladder are found, or if a tumor is grossly visible, a small portion of tissue is removed and sent to the laboratory for analysis.

How to prepare for the test:

You must sign an informed consent form. You will wear a hospital gown during the procedure. Make arrangements for travel 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 your urethra into your bladder. You will feel uncomfortable (a strong need to urinate) when the fluid has filled your bladder. You may feel a pinch during the biopsy. After the cystoscope is removed, your urethra may be sore and a burning feeling during urination may occur for 1 or 2 days.

Why the test is performed:

This test is most often performed to check for cancer of the bladder or urethra.
