HyCoSy / HyFoSy
HyCoSy is an ultrasound- based technique that is used to detect abnormalities of uterine cavity, fallopian tubes or tubal blockage. It is a safer alternative to the traditional hysterosalpingogram (HSG) or laparoscopy and dye test to check tubal patency.
    What are the common indications for having HyCoSy?
  • Investigation of sub-fertility
  • Recurrent miscarriage
    What are the advantages of having HyCoSy?
  • There is no radiation or iodinised contrast material involved.
  • HyCoSy is less uncomfortable than HSG as the fluid injected produces less irritation than the dye used in HSG.
  • It avoids anaesthesia required for laparoscopy.
  • It helps to avoid hospitalisation associated with laparoscopy.

How is this procedure organised?
A preliminary routine pelvic ultrasound is booked first especially if you haven't had one done at our clinic within 6 months of having HyCoSy. This is essential as it helps to identify certain situations where HyCoSy may not be feasible or necessary. An appointment for HyCoSy is done following this scan.

How long does this procedure take?
It usually takes about 30 minutes to do the procedure.

When is the best time to have HyCoSy done?
It is best done between Day 5- Day 10 of the menstrual cycle taking the first day of your periods as Day 1.

If you are unsure please contact us to discuss the timing of the procedure especially if you have irregular or infrequent periods.

How exactly HyCoSy is done?
A transabdominal scan with or without transvaginal scan may be repeated on the day of your procedure. Bladder is emptied prior to the procedure. Then you are asked to lie on your back with your legs placed in stirrups. A speculum is placed in the vagina and the cervix is cleaned using an antiseptic solution. A fine plastic tube (2mm) is then passed through the cervix and the small balloon at the tip is inflated to keep the catheter in place. Vaginal transducer is introduced again after taking the speculum out. Scan is performed as the saline/ contrast solution is injected through the catheter.

Will I need analgesia for the procedure?
You may require a single dose of painkillers such as Panadol following the procedure. Some women find the procedure slightly more uncomfortable than the others.

Will I need to take antibiotics before the procedure?
In general it is not necessary. However it may need to be considered in certain circumstances and you should discuss this with your doctor. The prescription is given to you by your doctor and the antibiotics to be taken 2 hours prior to having HyCoSy.

    Are there any contraindications for having HyCoSy done? You should not have the procedure in the following circumstances.
  • Acute pelvic infection
  • Unexplained pelvic tenderness
  • Suspected pregnancy
