Which term describes a procedure involving a visual examination within the bladder?

B is the term that accurately describes a procedure involving a visual examination within the bladder. Cystoscopy specifically refers to the use of a cystoscope, a specialized instrument, to visualize the internal lining of the bladder and the urethra. This procedure is commonly used to diagnose and treat conditions such as infections, bladder stones, or tumors within the bladder.

In contrast, endoscopy is a broader term that refers to the examination of internal organs using a flexible tube with a light and camera. While cystoscopy is a type of endoscopy, it does not solely refer to the bladder.

Urethroscopy refers specifically to the examination of the urethra, not the bladder itself, making it aim at a different anatomical focus.

Colposcopy involves the examination of the vagina and cervix, primarily used in gynecological settings, and is unrelated to the bladder. Each of these terms indicates distinct procedures focused on different anatomical areas, underscoring why cystoscopy is the term that precisely describes examining the bladder.
