What is saline infusion sonohysterography (SHG)?
Sonohysterography is an ultrasound procedure to evaluate the inside of a woman's uterus, where a small volume of saline is inserted into the womb, through the cervix. Sonohysterography may discover hidden causes of different genital problems, such as abnormal uterine bleeding, infertility or recurrent misscariages.
This method can detect:
Abnormal formations within the uterine cavity (fibroids or polyps)
Endometrial adhesions / synechiae
Malignant lesions / growths
Congenital uterine defects
How SHG is performed ?
SHG is typically performed in the first part of the menstrual cycle, after menstruation. The procedure starts with a transvaginal ultrasound examination, after which a narrow catheter is inserted into the uterine cavity, through the cervix. Ultrasound examination is continued while sterile saline is injected into the uterus.
Risks and complications of the procedure:
The test may cause mild cramps, bleeding or vaginal discharge. Some women may experience cramps for several hours. The most common sever complication of SHG is the pelvic infection; however it occurs in less than 1% of cases. You should contact your doctor if you experience pain and/or fever within the first 2 days after SHG. Some doctors prescribe painkillers and/or antibiotics before the procedure.
