Sonohysterogram (SHG)

The diagnostic test called sonohysterogram or SHG involves injecting sterile saline through the cervix into the uterus. The saline flows into the uterus enabling the physician to determine if the uterus is shaped normally. Intrauterine abnormalities can also be detected. This test does not check for tubal patency. The test is performed under ultrasound guidance.

First, a speculum is inserted into the vagina (the same as for a pap smear). This enables the physician to view the cervix (the opening to the uterus). The cervix is washed with iodine to reduce the chance of infection (risk 1 in 500). IF YOU ARE ALLERGIC TO IODINE PLEASE LET US KNOW. A small plastic tube is inserted through the cervix. Sometimes a tenaculum (metal clip) may need to be placed on the cervix to straighten it; this causes a pinching sensation. The tube is attached to a syringe containing sterile saline, which is injected into the uterus. On the ultrasound monitor you will be able to see the fluid as it enters the uterine cavity. You may feel some pelvic discomfort, similar to menstrual cramps, as the uterus fills up with saline. The entire procedure usually takes about 10 minutes.

In order to schedule a SHG, call (859) 260-1515 when your menstrual cycle begins. If your period starts on a weekend, please call the following Monday. The SHG will be scheduled between your period and time for ovulation usually between cycle days 5-14. Unless allergic, you should take 600 mg of ibuprofen (3 Advil tablets) one hour before the scheduled time to reduce cramping and discomfort. Please bring a sanitary pad as there may be some vaginal staining for 1-2 days.

You should check with your benefits from your insurance company to see if the SHG is a covered procedure. Some companies cover the entire procedure while others only cover a portion.
