Cystoscopy is a test performed with a thin, lighted tube that lets your doctor see inside your bladder and urethra.
It’s usually done in an outpatient setting with local anesthesia and only lasts about five to 10 minutes. Your doctor will insert a flexible tube (cystoscope) through your urethra (the tube that allows urine to pass out of the body) and into the bladder.

During the procedure, you may feel an uncomfortable fullness in your bladder or have the urge to urinate.
