What is the primary purpose of cystoscopy?

• A. Visualize the bladder and ureteral orifices; can obtain biopsy or perform interventions.
• B. Visualize the colon and rectum.
• C. Visualize the airway.
• D. Visualize the brain.

Answer: (A)

Cystoscopy is the direct endoscopic examination of the bladder, achieved by inserting a scope through the urethra into the bladder. The main purpose is to visualize the bladder’s interior and the openings of the ureters so you can detect abnormalities on the bladder lining. This direct view makes it possible to obtain tissue biopsies for pathology and to perform small procedures right there, such as removing lesions, sampling suspicious areas, or carrying out limited interventions like transurethral resections.

It isn’t used to view the colon, airway, or brain, which require other specialized scopes and procedures.
