Which radiographic study examines the uterus and fallopian tubes?

• A. Laparoscopy
• B. Hysterosalpingography
• C. Hysteroscopy
• D. Kidney, Ureter, Bladder (KUB)

Answer: (B)

Evaluating the uterus and fallopian tubes with imaging is best done with a study that introduces contrast through the cervix and follows its path under X-ray guidance. This reveals the shape of the uterine cavity and whether the fallopian tubes are open or blocked, providing direct information about tubal patency and uterine anatomy—crucial details when infertility or certain pelvic conditions are suspected. The study uses radiopaque contrast and real-time fluoroscopic imaging, so any filling defects, blockages, or tubal distension become visible.

Laparoscopy involves surgically inspecting the pelvis with a camera, not a radiographic study. Hysteroscopy uses a scope to visualize the inside of the uterus directly, again not radiographic imaging. A KUB is a plain abdominal film focusing on the kidneys, ureters, and bladder, and does not specifically evaluate the uterine cavity or fallopian tubes.
