Cystoscopy is a procedure that lets your doctor look directly inside your urethra and bladder. It can be used to:
Help diagnose a problem with your urethra, bladder, or kidneys.
Take a sample (biopsy) of bladder or urethral tissue.
Treat certain problems (such as removing kidney stones).
Place a stent to bypass an obstruction.
Take special x-rays of the kidneys.
Based on the findings, your doctor may recommend other tests or treatments.
A cystoscope is a telescope-like instrument that contains lenses and fiberoptics (small glass wires that make bright light). The cystoscope may be straight and rigid, or flexible to bend around curves in the urethra. The doctor may look directly into the cystoscope, or project the image onto a monitor.
To prepare, stop taking any medications as instructed. Ask whether you should avoid eating or drinking anything after midnight before the procedure. Follow any other instructions your doctor gives you.
Take any medications, such as aspirin or blood thinners
Have allergies to any medications
Cystoscopy is done in the doctor’s office or hospital. The doctor and sometimes a nurse are present during the procedure. It takes only a few minutes, longer if a biopsy, x-ray, or treatment needs to be done. During the procedure:
You lie on an exam table on your back, knees bent and legs apart. You are covered with a drape.
Your urethra and the area around it are washed. Anesthetic jelly may be applied to numb the urethra. Other pain medication is usually not needed. In some cases, you may be offered a mild sedative to help you relax. If a more extensive procedure is to be done, such as a biopsy or kidney stone removal, general anesthesia may be needed.
The cystoscope is inserted. A sterile fluid is put into the bladder to expand it. You may feel pressure from this fluid.
When the procedure is done, the cystoscope is removed.
If you had a sedative, general anesthesia, or spinal anesthesia, you must have someone drive you home. Once you’re home:
Drink plenty of fluids.
You may have burning or light bleeding when you urinate—this is normal.
Medications may be prescribed to ease any discomfort or prevent infection. Take these as directed.
Call your doctor if you have heavy bleeding or blood clots, burning that lasts more than a day, a fever over 101°F , or trouble urinating.
