Bladder Biopsy


A bladder biopsy is a procedure used to take a sample of your bladder tissue. The sample may be tested for cancer or other health problems. This procedure may be done during a cystoscopy. A cystoscopy is a procedure to look inside your urethra and bladder with a cystoscope. A cystoscope is a small tube with a light and camera on the end.

Seek care immediately if:

  • Your urine turns from pink to red, or you have clots in your urine.
  • You cannot urinate and your bladder feels full.
  • You have severe pain.

Contact your healthcare provider if:

  • You have a fever of 100.3°F (38°C) or higher.
  • Your pain or burning during urination becomes worse or lasts longer than 2 days.
  • Your urine stays pink for longer than 2 days.
  • You urinate less than usual, or still feel like you have to urinate after you use the bathroom.
  • You have questions or concerns about your condition or care.


You may need any of the following:

  • Antibiotics help treat or prevent a bacterial infection.
  • Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Read the labels of all other medicines you are using to see if they also contain acetaminophen, or ask your doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly. Do not use more than 4 grams (4,000 milligrams) total of acetaminophen in one day.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.


  • Drink liquids as directed. Your healthcare provider may recommend that you drink 6 to 8 eight-ounce cups of water every day for 2 days after your procedure.
  • Apply a warm, damp washcloth over your urethral opening. This may help to relieve discomfort. Keep the washcloth in place for 10 to 15 minutes every hour, or as directed.
  • Ask when you can return to regular daily activities. Your healthcare provider may recommend that you rest after your procedure. Directions for returning to your regular activities may depend on why you had a bladder biopsy. Do not have sex until your healthcare provider tells you it is okay. Sex may increase your risk for a urinary tract infection.

Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.
