Implantation failure or a miscarriage sometime happens because of an abnormality in the uterine cavity e.g. polyps, adhesions or scar tissue and congenital abnormalities. Even minor abnormalities can cause problems and dealing with them would improve your chances of success.
We can explore the uterine cavity by saline hysterosonography in which we inject saline in the uterine cavity through a thin catheter and check its integrity by ultrasound scan. If the scan reveals any abnormality, we can then perform hysteroscopy for its treatment.
Hysteroscopy still remains the method of choice for assessment of the uterine cavity, as it provides more accurate information and help with embryo transfer procedure.
Hysteroscopy is a procedure used to examine the inside of the uterus (womb). It is carried out using a hysteroscope, which is a narrow tube with a telescope at the end. Images are sent to a computer to give a close-up of the womb.
It helps determine:
- The size and depth of the uterine cavity, the presence of congenital abnormalities within the uterus, such as a septum that divides the inside of the uterus, or a double uterus
- The presence of polyps or fibroids in the uterine cavity and resecting them if possible
- Whether specific abnormalities of the endometrium (lining of the uterus) are present, e.g. hyperplasia (build-up the lining of the uterus), or cell changes that indicate inflammation
Why it is used?
A hysteroscopy can be used to help diagnosis cases where a woman’s symptoms suggest that there may be a problem with the womb. Symptoms might include:
- Repeated miscarriage
- Heavy or irregular periods
- Bleeding in between normal periods
- Pelvic pain
- Unusual vaginal discharge
