How the Test Will Feel Return to top
There may be slight discomfort as the cystoscope (a lighted instrument used to look at the bladder) is passed through your urethra into your bladder. You will feel an uncomfortable sensation -- similar to a strong urge to urinate -- when the fluid has filled your bladder.
You may feel a pinch during the biopsy. There may be a burning sensation when the blood vessels are sealed to stop bleeding (cauterized).
After the cystoscope is removed, your urethra may be sore. You may experience a burning sensation during urination for a day or two.
Sometimes when the suspicious area is larger, you will need general or spinal anesthesia to remove the area in question.
Why the Test is Performed Return to top
This test is most often performed to check for cancer of the bladder or urethra.
