Sonohysterography - Ultrasound of the Uterus (Saline Infusion Sonography)

Sonohysterography or saline infusion sonography (SIS) is a unique ultrasound examination that allows physicians to see inside the uterus in greater detail. Using a combination of ultrasound imaging and a minor infusion of saline (salt solution), this examination creates a picture of the uterine cavity. It is often advised for women with fertility issues, abnormal menstrual bleeding or prior to an IVF procedure. The reason for doing sis test is that it's non-surgical, safe, fast and very accurate, providing physicians with important information. 

What is a Sonohysterography (SIS)?

A sonohysterography is a more sophisticated type of ultrasound engineered especially to scan the uterine cavity. During a standard pelvic ultrasound, the inner lining of the uterus can sometimes not be seen clearly. Doctors overcome this by utilising a small volume of sterile saline solution. The saline increases the uterine cavity, allowing for easier detection of abnormalities that can't normally be viewed.

Referred to as the SIS test, saline infusion sonography or simply saline sonogram, this has become a common instrument in gynaecology and fertility medicine because of its accuracy and ease of use.

Why is a Sonohysterography Done?

A sonohysterography can be suggested by a physician for many reasons:

  • Detection of uterine abnormalities – It detects polyps (small abnormal tissue growths), fibroids, scar tissue (adhesions) or congenital (birth) anomalies.
  • Exploration of infertility – If a woman is having difficulty getting pregnant, an SIS test can demonstrate uterine problems adversely impacting their infertility. 
  • Preparations for pre-IVF or other fertility treatments – Although SIS is not required prior to these interventions, it should be utilised to confirm that the uterus is healthy and free of any defects in order to maximally reduce the chances of aborting a potential pregnancy.

In short, this is often the first step in the fertility assessment and planning process.

SIS Procedure (Step by Step)

Knowing the SIS procedure can be reassuring and help patients feel more prepared. Here is what typically transpires:

  • Positioning – The patient lies back on the exam table, similarly to a routine gynaecological examination.
  • Insertion of catheter – A flexible, thin tube (catheter) is then very gently placed through the cervix and into the uterus.
  • Saline infusion – Sterile saline is slowly infused into the uterine cavity. The fluid causes the cavity to distend (the walls will separate slightly).
  • Ultrasound imaging – A transvaginal ultrasound probe is placed to take close-up images. The fluid serves to illuminate the uterine lining and any abnormalities.

The procedure typically takes 10–15 minutes, is only mildly cramping for some women and is generally safe with few risks.

Saline Sonogram Before IVF

A saline sonogram prior to IVF is usually advised since the condition of the uterus has a direct bearing on the implantation of the embryo. Even slight problems, such as a small polyp or fibroid, can diminish the chances of IVF success.

By conducting SIS prior to IVF, physicians can:

  • Identify and repair issues early
  • Enhance implantation rates.
  • Lessen the risk of unsuccessful IVF cycles.

This renders the SIS test a helpful part of the IVF process, ensuring the uterus is in optimal condition before embarking on treatment.

Preparation & Aftercare

It is easy to prepare for an SIS test. Physicians might arrange it shortly after a menstrual cycle but before ovulation to guarantee the uterine lining is thinnest and pregnancy is impossible.

Preparation tips:

  • Some women will be instructed not to have intercourse for a day or two prior to the test.
  • Having a sanitary pad is useful, as a small amount of discharge may occur following the procedure.
  • Painkillers can be taken prior to the test if advised by the doctor.

Aftercare:

  • Mild cramping and spotting are expected in the first few hours.
  • No significant restrictions are necessary; patients can resume daily activities immediately.
  • If there is fever, extreme pain or heavy bleeding (rare), medical care should be sought.

Benefits:

  • Safe and non-invasive.
  • Rapid outpatient procedure.
  • Delivers clearer results than a conventional ultrasound.
  • Aids early diagnosis of fertility issues.
  • No radiation exposure.

Limitations:

  • Not suitable during pregnancy or in cases of active pelvic infection.
  • If abnormalities are found, further tests or procedures (like hysteroscopy) may still be required for confirmation and treatment.
