Why USG Hysterosalpingography (HSG) is Needed
The USG Hysterosalpingography test plays a vital role in diagnosing female infertility causes. Doctors recommend the HSG scan to:
-
Evaluate fallopian tube blockage or damage.
-
Detect uterine structural problems like septum or fibroid.
-
Assess tubal patency in women with difficulty conceiving.
-
Examine the uterine cavity for adhesions or polyps.
-
Follow up after tubal surgery or fertility treatment.
Compared to traditional HSG, the ultrasound-guided HSG offers accurate imaging without using radiation or iodine-based contrast. It provides dynamic imaging with real-time results and is more comfortable for patients. The test is typically performed after menstruation but before ovulation, ensuring optimal visualization of the reproductive organs.
Procedure of the USG HSG Test
The USG Hysterosalpingography procedure involves several simple, step-by-step actions under ultrasound guidance:
-
The patient lies on the examination table in a gynecological position.
-
A transvaginal ultrasound probe is inserted for baseline uterine imaging.
-
A sterile catheter is placed through the cervix into the uterine cavity.
-
A saline or echogenic contrast medium is injected gently.
-
As the fluid fills the uterus and travels through the tubes, ultrasound images are captured in real-time.
The entire HSG ultrasound test takes around 20–30 minutes. Patients may feel mild discomfort or cramping during the procedure, but it usually subsides quickly. There is no radiation exposure, and patients can resume normal activities immediately after the test.
Key Parameters and Image Interpretation
During a USG HSG scan, the following parameters are observed:
-
Uterine cavity shape, size, and any abnormal growths.
-
Tubal patency and fluid flow through both fallopian tubes.
-
Peritoneal spill pattern and symmetry.
-
Endometrial lining thickness and texture.
The report from the ultrasound HSG test helps clinicians determine whether the tubes are open or blocked, identify internal uterine problems, and plan appropriate fertility treatments or further interventions. Results are usually available soon after the test and are interpreted alongside the patient’s clinical history.
Benefits of Ultrasound Hysterosalpingography
The USG Hysterosalpingography test offers several clinical advantages:
-
Radiation-free and safer than traditional X-ray-based HSG.
-
Less pain and discomfort for patients.
-
Detailed visualization of uterine and tubal anatomy.
-
Immediate diagnosis with real-time imaging.
-
Quick recovery with no downtime.
-
Enhanced fertility assessment for conception planning.
Due to its safety and efficiency, the HSG ultrasound scan is recommended as a first-line test in infertility evaluation and reproductive care.
