Sonohysterogram: Procedure, Benefits, Risks, and Results

What Is a Sonohysterogram?

A sonohysterogram uses ultrasound and saline solution to look inside the uterine cavity. Saline makes the uterine cavity more prominent so that the doctors can have a better view of the uterine structures as compared to a regular pelvic ultrasound. Sonohysterograms are used routinely in gynaecology to help find problems in the uterus that could not be seen on standard images. The clarity available through this procedure makes it a very good diagnostic tool in reproductive medicine.

What Are the Reasons for Doing a Sonohysterogram?

A sonohysterogram may be recommended for different reasons. The most important reason a doctor recommends this procedure is to get clear and detailed pictures of the uterus. It helps doctors to diagnose certain medical problems. It is recommended in the following situations:

• Abnormal bleeding from the uterus
• To evaluate the cause of infertility and the reason for repeated miscarriages.
• To determine polyps, fibroids, or abnormal scar tissue in the uterus.
• To determine if the uterus is healthy before starting fertility treatments.
• To determine the outcomes of surgery done for the removal of polyps or fibroids.

How Do I Prepare for a Sonohysterogram?

It is important to prepare for a sonohysterogram to get accurate results. A sonohysterogram is to be scheduled a few days following your last menses and prior to ovulation. The procedure will typically be scheduled for the 5-10th day of the menstrual cycle after bleeding has stopped and before ovulation. Several preparations are important for this test:

• It is recommended to avoid intercourse for 2-3 days prior to the test.
• Also, if you have any allergies or infections, be sure to let your doctor know beforehand.
• You may take pain-relieving medicine, but only if prescribed by the doctor.
• Your doctor will advise whether you should arrive with an empty or partially full bladder, depending on the type of ultrasound being performed.
• The doctor may give you separate instructions based on your medical history.

What Happens During a Sonohysterogram?

You have to lie down on your back and place your feet apart with your knees bent, similar to a position for a pelvic examination. The doctor will place a thin, well-lubricated wand, called a vaginal ultrasound transducer, into the vagina to take images of the interior of the uterus.

• The healthcare provider will use a speculum to visualise the cervix.
• The provider will clean the cervical area with a cleansing swab.
• After this, they will place a thin catheter into the vagina, through the cervix, and into the uterus, due to which you may feel some cramping.
• The speculum will be removed from the vagina, and the ultrasound transducer will be reinserted to allow the saline (saltwater) solution to be infused into the uterus through the catheter. You may also feel some pressure or cramping at this time.
• After appropriate imaging is completed, the vaginal ultrasound transducer and the catheter will be removed from the vagina.

What to Expect After a Sonohysterogram?

After a sonohysterogram (SHG), you may return home and carry on with normal activities or your routine.but many clinicians recommend avoiding intercourse for 24–48 hours or until spotting resolves to reduce infection risk . You may experience:

Mild pain or cramps for which you can take over-the-counter pain medications.

You may have to use a sanitary pad, as thin, watery discharge is experienced for a few hours following the procedure due to saline solution draining from your vagina.

It is also common to experience light red or brown vaginal spotting for several days due to irritation. But it is normal, and you do not have to worry about it.

How Are Sonohysterogram Results Interpreted?

A sonohysterogram evaluates the internal structures of your uterus. The uterus may appear:

• Normal in shape and structure
• Thickened endometrium
• Large noncancerous tumors or fibroids may be present
• Small growths or polyps may be seen in the endometrial lining
• Endometrial cancer may be detected
• Adenomyosis

The doctor will review the test results. The doctor may recommend a biopsy or other imaging tests and may advise on what kind of treatments to consider based on the results. Some health care providers offer a follow-up plan once the testing is completed, including follow-up appointments, imaging checks, education about conditions identified by the results, or possible next steps depending on the diagnosis.

What Are the Advantages of Sonohysterogram?

A sonohysterogram has several benefits over the standard ultrasound procedure. Important benefits of a sonohysterogram are:

It provides high-quality diagnostic images of the uterine cavity. Abnormalities such as fibroids, polyps, scar tissue, and irregular shapes of the uterus are more easily identified with the enhanced image quality of the sonohysterogram.

It can identify abnormalities with the inside of the uterus which would be difficult to see on a normal pelvic scan. The procedure is believed to be simple and takes about 15-30 minutes.

It does not require an incision or anesthesia, nor is an overnight hospital stay needed, unlike other surgical diagnostic procedures.

There is no exposure to the radiation, which makes it a safe procedure.

It is a useful test to evaluate the uterine cavity abnormalities of a woman.

Due to accuracy and safety, it is most often the first step in diagnosing reproductive problems in women rather than proceeding with more invasive modalities.

What Are the Potential Risks or Side Effects Associated with a Sonohysterogram?

Some women might have light spotting or feel temporary discomfort and mild cramps. Though infections are uncommon, they can still happen. Serious complications are rare with this procedure. Listen to your doctor’s post-procedure instructions closely and let them know immediately if you notice anything unusual.

What Is the Difference Between a Hysterosalpingography and a Sonohysterogram?

Hysterosalpingography (HSG) is a radiographic imaging technique that uses radiation and contrast dye to see the internal structures of the uterus. Doctors usually perform this test to evaluate possible underlying causes of infertility, whereas sonohysterography is done to diagnose. An HSG is used to check for blockages in the fallopian tubes that could lead to infertility problems that are not always visible through a sonohysterogram.

What Is the difference between an ultrasound and a sonohysterogram?

In a sonohysterogram, a saline solution is inserted into the uterine cavity, whereas in a normal pelvic or transvaginal ultrasound, no saline is used. A sonohysterogram is an advanced procedure that helps the doctor to view the uterine cavity and associated structures more clearly to get detailed images.

Is a sonohysterogram a painful procedure?

It’s not unusual to experience some discomfort during the process, particularly when the catheter is placed into the uterus. You may feel some pressure and cramping sensations caused by the saline used to expand the uterus for the procedure; however, these sensations will go away after completion of the procedure and after the procedure is completed.

When Should You Call a Doctor?

You may experience some side effects after this test. You can call your doctor if you experience symptoms such as intense abdominal pain, heavy bleeding, chills and fever, and foul-smelling discharge. These symptoms may indicate an infection or other issues and require urgent attention.

Conclusion

In conclusion, a sonohysterogram test (SHG) is an invaluable diagnostic tool for evaluating the overall health of your uterine cavity. It can be used to assess the underlying causes of problems such as heavy abnormal bleeding or infertility by providing accurate images of polyps, fibroids, and other abnormalities within the cavity of the uterus. A sonohysterogram is safe, reliable, and relatively inexpensive to perform. The test should only take about 30 minutes to complete and is almost always well-tolerated by the majority of women; it does not involve the use of any radiation. Prior to scheduling your SHG procedure, you should know the details of what will occur before, during, and after the procedure, which will also aid you in making the correct decisions and help to ask questions from the doctor regarding your symptoms and what action should be taken next.
