Tubal Patency Ultrasound
Tubal patency is a minimally invasive ultrasound technique that produces images of the inside of the uterus and fallopian tubes. A saline fluid mixed with air allows for more detailed imaging, as it is injected through the cervix and into the uterus and fallopian tubes.
This ultrasound is used to create images of the uterine cavity and tubes.
How is the tubal patency ultrasound performed?
- The procedure begins with a trans-abdominal ultrasound examination prior to the saline/air injection. The patient will then be asked to assume the lithotomy position (lying on back with feet in stirrups) to begin the ultrasound examination.
- The cervix will be cleaned with a betadine solution and a small catheter will be inserted through the cervix to rest inside of the uterus cavity. The speculum will then be removed and a probe will be placed in the vagina. Next, the saline/air solution will be slowly injected in the cavity to fill the uterus and images of the fallopian tubes will be obtained.
- Following the examination the patient will be asked to remain in the waiting area for several minutes to monitor any discomfort. Over the counter medications should be able to minimize any discomfort that some women might feel. You may experience vaginal spotting following this procedure – this is entirely normal. You can expect this procedure to last about 30 minutes. It is recommended that you have a support person attend the appointment, if possible, in the event of moderate cramping that could, but rarely, occur.
