HSG/SIS EVALUATIONS 

HSG/SIS EVALUATIONS

HYSTEROSALPINGOGRAM (HSG)

SALINE INFUSION SONOGRAM (SIS)

Our care team at Troché Fertility Centers understands the stressful nature of completing the fertility tests in order to find answers. We offer both HSG (“dye test”) and SIS (Saline sono) at our Centers to meet your specific needs.

WHAT IS A HSG?

A test conducted by a physician where dye is injected through the cervix in order to see whether a woman’s fallopian tubes are open and to document the shape of the interior of the uterus.

HYSTERO = UTERUS + SALPINGO = FALLOPIAN TUBES + GRAM = X-RAY

WHY IS THIS TEST DONE?

In a normal menstrual cycle, an egg is released from an ovary, passes through the fallopian tube, and into the uterus. There can be a blockage of this passage at any point of the journey, and the HSG can reveal an obstruction and its location. Additionally, during the HSG the shape of the uterus is noted to rule out anatomic irregularities that might interfere with pregnancy. X-rays are taken briefly during the procedure and creates a permanent record for future reference.

PROCEDURE:

The HSG is performed after the menstrual flow is completed, but before ovulation occurs. The test involves injecting contrast media or dye through the cervix into the uterus and seeing if it can flow into the fallopian tubes. X-rays are taken periodically to document the flow of the dye through the tubes. A normal test shows free flow of the dye through the fallopian tubes. An abnormal test shows a blocked tube or dilation (swelling) called a hydrosalpinx of the tube at the blocked point (as seen in the picture below).

HSG TEST RESULTS:
Normal HSG Result
Abnormal HSG Result

WHAT HAPPENS NEXT?

Immediately after the HSG, Dr. Troché will review the test results with you.

If your HSG is normal, no tubal damage was seen and the uterine cavity is normally shaped. Once all the test results (HSG, blood tests, and semen analysis) are available, you’ll meet with Dr. Troché to develop your personalized treatment plan.

If your HSG is abnormal, Dr. Troché will discuss the results and how to proceed next.

WHAT IS A SIS?

A test conducted by a physician where normal saline is injected into the uterus in order to evaluate the inside of the uterine cavity.

WHY IS THIS TEST DONE?

Abnormalities of the uterine cavity can interfere with implantation of a fertilized egg by changing the shape of the uterus. These abnormalities are commonly caused by growths, such as fibroids or polyps, or scar tissue from a previous procedure or infection.

This test is performed when only information about the uterine cavity is needed (for IVF) as it provides no information about the patency of the fallopian tubes. It does not involve x-rays.

PROCEDURE:

The SIS is performed after the menstrual flow is completed, but before ovulation occurs.  Normal saline is injected via a small tube (catheter) through the cervix and into the uterus. Using ultrasound, Dr. Troché can then evaluate the inside of the gently distended uterus for any abnormality. The examination takes only a few minutes.

SIS TEST RESULTS:     
Normal SIS Result
Abnormal SIS Result 

WHAT HAPPENS NEXT?

Immediately after the SIS, Dr. Troché will review the test results with you.

If your SIS is normal the uterine cavity is normally shaped. Once all the test results (SIS, blood tests, and semen analysis) are available, you’ll meet with Dr. Troché to develop your personalized treatment plan.

If your SIS is abnormal, Dr. Troché will discuss the results and how to proceed next.
