Sonohysterography

Sonohysterography, also called fluid ultrasound, is a simple technique for obtaining an image of the uterine cavity. It is usually performed in a doctor's office without anesthesia. Ibuprofen, or other NSAIDs, may be given to reduce cramping.

A thin catheter is introduced into the uterus. A transvaginal ultrasound is then performed while a small quantity of saline is instilled into the uterus. The uterus is expanded by the fluid, allowing the ultrasonic imaging of abnormalities such as fibroids, polyps or adhesions. Fluid observed in the pelvic cavity indicates that at least one tube is patent.
