A cystoscopy is a procedure that lets a doctor look inside your bladder and urethra. The urethra is the tube that carries urine from the bladder to outside the body.
The doctor uses a thin, lighted tool called a cystoscope. With this tool, the doctor can look for kidney or bladder stones. The doctor can also look for tumors, bleeding, or infection.
If you are in a clinic and you are awake, you will get gel to numb your urethra. This makes the procedure more comfortable. Then the doctor puts the tube into your urethra and moves it into your bladder. Next, the doctor fills your bladder with liquid. This helps the doctor see better. It may cause you to feel pressure in your bladder area for a short time.
If you are in the hospital, you may get medicine to make you sleep during the procedure. While you are asleep, the doctor can take samples of tissue. These will be checked for cancer and other problems. This is called a biopsy. If you have a biopsy, you may have a small amount of blood in your urine for several days. You may also need a catheter. It's a tube that drains urine from your bladder. Your doctor will take it out at your follow-up visit.
Cystoscopy may be done to:
Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.
The test is done in a hospital or the doctor's office.
You'll need to take off all or most of your clothes. You'll have a cloth or paper covering to use during the test.
About an hour before the test, you may get a sedative to help you relax. An intravenous (IV) needle may be placed in your arm to give you other medicines and fluids. You will lie on your back on a table with your knees bent, legs apart. Your feet or thighs may be placed in stirrups. Your genital area is cleaned with an antiseptic solution. Your belly and thighs are covered with sterile cloths.
For this test, you will have one of three kinds of anesthesia.
After the anesthetic takes effect, the cystoscope tube is inserted into your urethra and slowly moved into your bladder. If your urethra has a spot that is too narrow, other smaller tools are inserted first. They will gradually make it large enough for the tube.
Next, the doctor injects either sterile water or salt water (saline) to help make your bladder larger and to create a clear view. The doctor may also inject medicine to reduce chances of infection.
The doctor can also insert tiny tools through the tube to collect tissue samples for biopsy. The tissue samples are sent to the lab to be checked.
If a local anesthetic is used, you may be able to get up right after the test. If a general anesthetic is used, you will stay in the recovery room until you are awake and able to walk. (This usually takes an hour or less.) You can eat and drink as soon as you are fully awake and can swallow without choking. If a spinal anesthetic was used, you will stay in the recovery room until feeling and movement below your chest returns. (This usually takes about an hour.)
The tube is usually in your bladder for only 2 to 10 minutes. But if other X-ray tests are done at the same time, the entire test may take up to 45 minutes or longer.
If you are put to sleep with a general anesthetic, you won't feel anything during the test. After the anesthetic wears off, your muscles may feel tired and achy. The medicine gives some people an upset stomach.
If a local anesthetic is used, you may feel a burning sensation or an urge to urinate when the cystoscope tube is inserted and removed. When sterile water or saline is put in your bladder, you may feel a cool sensation, an uncomfortable fullness, and an urgent need to urinate. Try to relax during the test by taking slow, deep breaths. Also, if the test takes a long time, lying on the table can become tiring and uncomfortable.
If a spinal anesthetic is used, you may find it uncomfortable to lie curled up on your side while the anesthetic is injected. You will probably feel a brief sting when the medicine is injected. The day after the test, you may feel tired and have a slight backache.
Most people report that this test is not nearly as uncomfortable as they thought it would be.
Cystoscopy is generally a very safe test. General anesthesia has some risks. The test doesn't affect sexual function.
The most common side effect is a short-term swelling of the urethra. This can make it hard to urinate. A catheter inserted in your bladder can help drain the urine until the swelling goes away. Bleeding sometimes occurs, but it usually stops on its own.
You may have a mild infection in the urinary tract after the test. This can usually be prevented or treated by taking medicine before and after the test. In rare cases, the infection can spread through the body. And in very rare cases, usually with seriously ill people, the infection can be life-threatening.
Another rare complication is a puncture of the urethra or bladder by one of the tools. This puncture needs surgery to repair.
Your doctor may be able to talk to you about some of the results right after the test. The results of a biopsy usually take several days.
The urethra, bladder, and ureters are normal.
There are no polyps or other abnormal tissues, swelling, bleeding, narrow areas (strictures), or structural problems.
There is swelling or narrowing of the urethra because of previous infections or an enlarged prostate gland.
There are bladder tumors (which may or may not be cancerous), polyps, ulcers, urinary stones, or inflammation of the bladder walls.
Problems in the structure of the urinary tract present since birth (congenital) are seen.
In a woman, pelvic organ prolapse is present.
