Cystoscopy is used to diagnose, monitor and treat conditions affecting the bladder and urethra. Your doctor might recommend cystoscopy to:

• Investigate causes of signs and symptoms. Those signs and symptoms can include blood in the urine, incontinence, overactive bladder and painful urination. Cystoscopy can also help determine the cause of frequent urinary tract infections. However, cystoscopy generally isn't done while you have an active urinary tract infection.
• Diagnose bladder diseases and conditions. Examples include bladder cancer, bladder stones and bladder inflammation (cystitis).
• Treat bladder diseases and conditions. Special tools can be passed through the cystoscope to treat certain conditions. For example, very small bladder tumors might be removed during cystoscopy.
• Diagnose an enlarged prostate. Cystoscopy can reveal a narrowing of the urethra where it passes through the prostate gland, indicating an enlarged prostate (benign prostatic hyperplasia).

Your doctor might conduct a second procedure called ureteroscopy (u-ree-tur-OS-kuh-pee) at the same time as your cystoscopy. Ureteroscopy uses a smaller scope to examine the tubes that carry urine from your kidneys to your bladder (ureters).

Complications of cystoscopy can include:

• Infection. Rarely, cystoscopy can introduce germs into your urinary tract, causing an infection. Risk factors for developing a urinary tract infection after cystoscopy include advanced age, smoking and unusual anatomy in your urinary tract.
• Bleeding. Cystoscopy might cause some blood in your urine. Serious bleeding occurs rarely.
• Pain. After the procedure, you might experience abdominal pain and a burning sensation when you urinate. These symptoms are generally mild and gradually get better after the procedure.

Signs and symptoms of a serious complication

Call your doctor or go to the nearest emergency room if you experience:

• An inability to urinate after cystoscopy
• Bright red blood or heavy blood clots in your urine
• Abdominal pain and nausea
• Chills
• A fever higher than 101.4 F (38.5 C)
• Pain or burning during urination that lasts more than two days

You might be asked to:

• Take antibiotics. Your doctor might prescribe antibiotics to take before and after cystoscopy, especially if you have trouble fighting off infections.
• Wait to empty your bladder. Your doctor might order a urine test before your cystoscopy. Wait to empty your bladder until you get to your appointment in case you need to give a urine sample.

Prepare for sedation or anesthesia

If you'll receive an intravenous (IV) sedative or general anesthetic during your cystoscopy, plan ahead for your recovery. You'll need to ask someone to drive you home.

During cystoscopy

A simple outpatient cystoscopy can take five to 15 minutes. When done in a hospital with sedation or general anesthesia, cystoscopy takes about 15 to 30 minutes.

Your cystoscopy procedure might follow this process:

• You'll be asked to empty your bladder. Then you'll lie down on a table on your back. You'll likely be positioned with your feet in stirrups and your knees bent.
• You may or may not need a sedative or anesthetic. If you receive a sedative, you'll feel sleepy and relaxed during the cystoscopy, but you'll still be aware. If you receive a general anesthetic, you won't be aware during the procedure. Both types of medication may be given through a vein in your arm.
• Your doctor will insert the cystoscope. A numbing jelly will be applied to your urethra to help prevent pain when the cystoscope is inserted. After waiting a few minutes for the numbing, your doctor will carefully push the cystoscope into your urethra, using the smallest scope possible. Larger scopes might be needed to take tissue samples or pass surgical tools into the bladder.
• Your doctor will examine your urethra and bladder. The cystoscope has a lens on the end that works like a telescope to magnify the inner surfaces of your urethra and bladder. Your doctor might place a special video camera over the lens to project the images onto a video screen.
• Your bladder will be filled with a sterile solution. The solution inflates the bladder and allows your doctor to get a better look inside. As your bladder fills, you may feel the need to urinate. You'll be encouraged to do so once the procedure is finished.
• Tissue samples might be taken. Your doctor might take tissue samples for lab testing, or perform various other procedures during the cystoscopy.

After the cystoscopy

You might be allowed to resume your daily routine. If you've had sedation or general anesthesia, you might be asked to remain in a recovery area to allow the effects of the medication to wear off before you leave.

Side effects after cystoscopy might include:

• Bleeding from your urethra, which can appear bright pink in your urine or on toilet tissue
• A burning sensation during urination
• More frequent urination for the next day or two

You can relieve some of the discomfort if you:

• Drink water to flush irritants out of your bladder. Try to drink 16 ounces (473 milliliters) of water each hour for the first two hours after the procedure.
• Take an over-the-counter pain reliever.
• Place a warm, damp washcloth on the opening to your urethra to ease pain, repeating as needed.
• Take a warm bath, unless your doctor asks you to avoid baths.

Call your doctor if you have concerns after your cystoscopy.

Your doctor might be able to discuss the results immediately after your procedure.

Or, your doctor might need to wait to discuss the results at a follow-up appointment. If your cystoscopy involved collecting a biopsy to test for bladder cancer, that sample will be sent to a lab. When the tests are complete, your doctor will let you know the results.
