‍Sonohysterography procedure

Sonohysterography (SHG), also referred to as saline infusion sonography (SIS), is a safe and relatively painless ultrasound procedure used as an initial screening method to identify potential issues related to the uterus and ovaries. Lasting no longer 30 minutes, the SHG involves inserting a transducer wand into the vagina and cervix, delivering fluid into the uterus. Simultaneously, sound waves transmitted through gel create a real-time image of the uterus’s interior. The saline solution enhances the ultrasound, offering clearer details of the uterus’s structure compared to traditional ultrasounds. 

Saline infusion sonohysterography indication

Healthcare practitioners use sonohysterography to help diagnose a number of medical conditions related to infertility. If a patient experiences abnormal uterine bleeding, infertility, repeated miscarriages, or an abnormal pelvic exam, SHG is frequently recommended to determine if there may be additional contributing factors at play, including:

• Uterine fibroids
• Uterine polyps
• Scarring inside the uterus
• Abnormal shape of the uterus
• Uterine cancer
