A cystoscope is used to look inside which structures?

• A. Examine esophagus
• B. Inspect lungs
• C. Look inside bladder and urethra
• D. View brain ventricles

Answer: (C)

A cystoscope is an instrument designed to visualize the urinary tract, specifically the bladder and the urethra. It is inserted through the urethral opening and advanced into the bladder, allowing the clinician to inspect the bladder lining for stones, tumors, inflammation, or other abnormalities and to perform related procedures such as biopsies or catheter placement. The other options involve different body areas that require distinct scopes—esophagus with an upper GI endoscope, lungs with a bronchoscope, and brain ventricles with a neurosurgical scope—so the bladder and urethra are the structures examined with a cystoscope.
