Cystoscopy (sis-TOS-koh-pee) A cystoscopy is a procedure that allows your doctor to examine your urethra, bladder, and openings to your ureters. Your ureters are the tubes that carry urine from your kidneys to your bladder (see Figure 1).

These needle biopsies were once discouraged but are now done in very specific circumstances.
