Which procedure provides a visual examination of the uterus using an endoscope?

• A. Hysteroscopy
• B. Laryngoscopy
• C. Hysterosalpingography
• D. Lumbar puncture (spinal tap)

Answer: (A)

Hysteroscopy is the procedure that provides a visual examination of the uterus using an endoscope. The hysteroscope, a thin, lighted instrument with a camera, is inserted through the cervix into the uterine cavity, allowing direct viewing of the endometrium and any intrauterine abnormalities. A distension medium such as saline is often used to gently expand the cavity for a clearer view, and the approach can be purely diagnostic or combined with tools to treat conditions like polyps, submucosal fibroids, or intrauterine adhesions. This is different from other options: laryngoscopy looks at the larynx, hysterosalpingography uses radiographic contrast to image the uterus and fallopian tubes without an endoscope, and a lumbar puncture collects cerebrospinal fluid from the spine.
