• Cystoscopy



    A cystoscopy is a procedure to examine the bladder with a lighted scope. The scope allows the doctor to look through the urethra and into the bladder. The urethra is a tube that carries urine from the bladder to the outside of the body.

    What to Expect

    Prior to Procedure

    This procedure is usually done in your doctor's office.


    Local anesthesia is used to numb the area in and around the urethra. A sedative may also be given to help you relax.

    Description of the Procedure

    You will lie on an exam table. A cystoscope will be inserted through the urinary opening, into the urethra, and into the bladder. Your bladder will be drained of urine. A sample will be kept for testing. Next, your bladder will be filled with sterile water or saline solution. This will allow a better view of the bladder walls. The bladder and urethra will be examined.

    How Long Will It Take?

    Up to 15 minutes

    How Much Will It Hurt?

    Local anesthesia will keep you free from pain. You may feel some discomfort or the urge to urinate when the bladder is filled during the exam.

    Post-procedure Care

    After the procedure, you may experience a burning sensation or see small amounts of blood when you urinate.

    Call Your Doctor

    After arriving home, contact your doctor if any of the following occur:
    • Frequency, urgency, burning, or pain when urinating
    • You are unable to urinate or empty your bladder completely
    • Blood in your urine after 24 hours
    • Signs of infection; including fever and chills
    • Pain in your abdomen, back, or side
    In case of an emergency, call for emergency medical services right away.
