Tubal assessment may be recommended in some women who are having difficulty conceiving. This imaging procedure examines the patency of the fallopian tubes. That is, whether the fallopian tubes leading from the ovaries to the uterus are clear and unimpeded for the passage of sperm and ovum.
A preliminary gynaecological ultrasound will be performed prior to the procedure to assess the pelvic anatomy and allow for appropriate procedural planning.
A speculum is passed into the vagina, like a PAP smear and a thin catheter is then passed through the cervix into the uterine cavity. Once in place, a small balloon at the tip of the catheter is inflated to keep it in place.
The speculum is removed, and the ultrasound probe is reinserted into the vagina.
The contrast medium is then prepared and injected through the catheter and the tubes are examined. Contrast should be seen flowing through the fallopian tube and spilling around the ovary on both sides.
