تصوير الرحم المائي

What is it?

A hysterosonography (or sonohysterography) is a particular type of transvaginal ultrasound which allows the doctor to analyse the uterine cavity.

What does it involve?

It is a minimally invasive procedure: you don’t need to do anything to prepare for it. The hysterosonography is usually carried out in two steps:

• first, you will have a simple transvaginal scan done to check the shape and size of your uterus.
• the doctor will analyse your uterine surface after the scan. Then, a small catheter will inject a small amount of sterile saline, which will distend the uterine cavity. This will allow the doctor to better check your uterus and proceed with the ultrasound.

What is it for?

This technique can identify uterine abnormalities such as polyps, fibroids, uterine malformations, congenital anomalies, malignant tumours or endometrial adhesions.
