What is saline hysterography (SHG)?
Sonohisterography consists of the ultrasound visualization of the uterus and the uterine cavity while sterile saline is introduced into the cavity. The purpose of SHG is to detect abnormalities of the uterus and endometrial cavity (uterine).
How is SHG performed?
SHG is usually performed in the first part of the menstrual cycle, after menstruation.
The procedure begins with a transvaginal ultrasound examination, after which a narrow catheter is inserted through the cervix into the uterine cavity. Ultrasound examination is continued while saline is introduced into the uterus. The uterine cavity is filled with sterile solution to improve the details of the images obtained. Formations that occupy the uterine cavity such as endometrial polyps or endocavitary fibroids are visualized
very well with this technique.
What are the risks and complications of the procedure?
SHG is a very safe procedure.
May cause mild cramping, bleeding or vaginal discharge. Some women may have cramps for several hours.
The most common severe complication of SHG is pelvic infection; however, it occurs in less than 1% of cases and involves a pre-existing tubal pathology.
You should contact your doctor if you experience pain and / or fever within the first 2 days of performing SHG.
Some doctors prescribe painkillers and / or antibiotics before the procedure.
