Also called cystourethroscopy, a cystocscopy is an examination in which a scope (a flexible tube and viewing device) is inserted through the urethra to examine the bladder and urinary tract for structural abnormalities or obstructions, such as tumors or stones. Samples of the tissue (called a biopsy) may be removed through the cystoscope for examination under a microscope in the laboratory.
