Saline Infusion Sonography
Patients undergoing investigation for infertility have a high incidence of polyps in the uterine cavity which may be responsible for their inability to conceive. Using sonohysterography (SIS) a doctor can get a better view of the uterine cavity to help determine the direction of further diagnosis and treatment if required.
The low risk procedure has a comparable accuracy to hysteroscopy and along with transvaginal ultrasound, is an ideal non-invasive screening test for intra-uterine abnormalities.
The sonohysterography uses an infusion of sterile saline through a soft plastic catheter placed in the cervix in conjunction with transvaginal ultrasound. The saline infusion distends the uterine cavity and provides an excellent contrast to the lining, giving improved visualization of uterine and endometrial pathology.
The main indications for this procedure include:
- Abnormal uterine bleeding both pre and post menopausal
- Investigation of infertility and recurrent miscarriage
- Endometrial assessment for patients before and after treatment
- Suggestion of a mass in the endometrial cavity on ultrasound
