What is a saline sonogram?
A saline sonogram, also called saline infusion sonogram or SIS, is a procedure which is used to look closely at the uterus (womb), the ovaries, and the shape of the uterine cavity (womb lining). It uses sterile fluid and sound waves to produce pictures of these internal structures and reproductive organs. At Welbeck, this procedure takes place in our state-of-the-art Women’s Health centre.
You might need a saline sonogram if you:
had an ultrasound that was inconclusive
are struggling to conceive
have pelvic pain
have had 2 or more miscarriages in a row
get abnormal menstrual cramps
will be having IVF treatment and embryo transfer
have irregular or heavy bleeding
have suspected uterine cancer
have suspected uterine polyps or fibroids
What to expect with Saline Sonogram
At Welbeck, saline sonograms are carried out by a consultant radiologist or gynaecologist. To begin, you’ll need to remove your clothing from the waist down and cover yourself with a sheet, which we’ll provide.
You can expect the following for a saline sonogram:
Once you’ve emptied your bladder, your consultant will ask you to lie back on the bed.
They’ll gently place a smooth, tube-shaped tool (a speculum) into your vagina to open it and see your cervix in detail.
Your cervix and vagina will be cleaned with a sterile solution.
A soft, flexible tube (thinner than the inside of a pen) is passed into the uterus via the cervix.
The speculum is removed, and a slim ultrasound probe is inserted.
While the consultant takes images of your uterus, they’ll gently inject a sterile liquid through the thin tube.
Once enough images have been recorded, the probe and the tube will be removed.
After the procedure, the images will be examined, and a report will be compiled. Your consultant will use these results to develop a treatment plan, which they will discuss with you.
Please note that a saline sonogram does not include a full pelvic gynaecological assessment or test if tubes are open. For this, you will need a HyCoSy.
A saline sonogram is a very safe procedure with very few risks. You may feel some discomfort and cramping during and after it, but this should settle down quickly. There’s a small risk of pelvic infection, but this is very rare. You’ll be given antibiotics after your procedure to minimise the risk of infection.
A saline sonogram is best performed when your period ends, between days 5 and 14 of your cycle. This is when the endometrium (the lining) is at its thinnest, which is considered the best time to fully assess the inside of your womb. When you make your appointment, let us know when this window in your cycle will be.
There’s no other specific preparation needed, but you must abstain from intercourse from the first day of your period until the day of your test.
You may want to wear comfortable, loose-fitting clothing, such as a skirt or dress that you can lift up. This can make removing your clothing from the waist down feel less daunting.
You’ll be able to go home right after your procedure and carry on with normal activities. The saline fluid will drain out of your uterus for a few hours, so it may help to bring a sanitary pad or pantyliner with you.
You might also have:
cramping
light spotting
fluid leaking from your vagina
These are all normal symptoms. If you feel mild pain after the procedure, you can take painkillers and use a heat pad to ease discomfort.
See your doctor if:
the pain is severe
you have a fever
there’s a change in the type or amount of your vaginal discharge

Frequently asked questions
You can't have a saline sonogram if you're pregnant or think you might be pregnant, or if you have an active pelvic infection, such as pelvic inflammatory disease (PID) or hydrosalpinx.
You might feel slight discomfort during a saline sonogram, especially if you’re post menopausal. Your doctor may provide medication in advance to help soften your cervix in this case. Some women notice slight cramping, bloating or pressure when the tube and saline solution are inserted, but this usually goes away quickly after the test.
A saline sonogram only assess the shape and health of your womb lining (endometrium) only. An internal (transvaginal) ultrasound is a full internal assessment of your reproductive system. Saline Sonogram does not include a full assessment. If you wish to have a saline sonogram and a full pelvis ultrasound please book for HyCoSy
A saline sonogram appointment should take about 45 minutes in total. The part that involves injecting fluid into your uterus only lasts 5 to 10 minutes.
