Which procedure involves visualizing the urinary bladder with an endoscope?

• A. Cystography
• B. Cystoscopy
• C. Ureteroscopy
• D. Intravenous Pyelogram

Answer: (B)

Visualizing the urinary bladder with an endoscope is cystoscopy. In this procedure, a cystoscope—an instrument with a light and camera—is inserted through the urethra into the bladder to directly inspect the bladder lining. This allows real-time viewing, biopsy, or treatment as needed. The other options are imaging tests that don’t involve looking inside the bladder with a scope: cystography uses X-ray images with contrast to outline the bladder; ureteroscopy examines the ureters and sometimes the renal pelvis with a scope; and an intravenous pyelogram uses IV contrast and X-rays to image the urinary tract without endoscopic visualization.
