At a glance
An obstetric/gynaecologic ultrasound is a painless imaging test that uses sound waves to produce pictures of the uterus (womb), ovaries, fallopian tubes, and, during pregnancy, the developing baby. The sound waves are emitted by a handheld probe, bounce off internal structures, and return as signals that a computer converts into a real-time image on a screen.
No radiation is involved, which is why this scan is the standard first-line tool for monitoring pregnancy and investigating gynaecological problems. The probe is either moved across the lower abdomen or, when greater detail is needed, gently inserted into the vagina. The vaginal approach (called a transvaginal ultrasound) gives a clearer picture of the uterus and ovaries because the probe sits closer to those organs.
Medical Condition
Doctors request this scan both during pregnancy and outside of it, to investigate a wide range of conditions affecting the female reproductive system.
- Confirming a pregnancy and checking the baby's heartbeat in early weeks.
- Dating the pregnancy and estimating the due date.
- Screening for structural differences in the baby (anomaly scan, usually around 18 to 20 weeks).
- Monitoring the position of the placenta (the organ that feeds the baby).
- Checking the amount of amniotic fluid (the liquid surrounding the baby).
- Detecting multiple pregnancies such as twins or triplets.
- Investigating abnormal or heavy menstrual bleeding.
- Looking for fibroids (non-cancerous growths in or around the uterus) or polyps (small tissue growths inside the uterus).
- Evaluating pelvic pain or pressure.
- Assessing ovarian cysts (fluid-filled sacs on the ovaries).
- Supporting fertility investigations, including follicle monitoring during IVF treatment.
- Checking for a suspected ectopic pregnancy (a pregnancy growing outside the uterus, which is a medical emergency).
- Guiding the placement of an IUD (intrauterine device, a contraceptive placed inside the uterus).
There are very few situations where this scan is not suitable. A transabdominal scan (probe on the abdomen) may give a poor image if the bladder is not full enough or if there is significant abdominal tissue. Your doctor will choose the approach that gives the clearest information for your specific situation.
Risks & Complications
An obstetric/gynaecologic ultrasound is one of the safest medical tests available. It uses sound waves, not radiation, and decades of use in pregnancy have not shown any harm to mothers or babies.
- Mild discomfort during a transvaginal scan from the probe; this is not painful for most people.
- Slight pressure or urgency to urinate during a transabdominal scan if the bladder needs to be full.
- A small risk that the scan does not detect every abnormality, meaning a normal result does not guarantee a problem-free pregnancy or normal anatomy.
- Rarely, minor vaginal spotting (light bleeding) after a transvaginal scan; this usually settles quickly.
- In very rare cases, anxiety caused by incidental findings (unexpected findings unrelated to the reason for the scan) that require further investigation.
Preparation & Procedure
Preparation depends on which type of ultrasound your doctor orders. For a standard transabdominal scan, you are usually asked to drink several glasses of water in the hour before the appointment and to avoid urinating, so the bladder is full. A full bladder pushes the intestines aside and gives a clearer view of the uterus. For a transvaginal scan, the opposite applies: you will be asked to empty your bladder just before the scan begins.
No fasting is required for this scan. You do not need to stop any regular medication beforehand unless your doctor specifically instructs otherwise. Smoking and alcohol restrictions do not apply to the scan itself, though if you are pregnant, your obstetric team will have separate guidance on those.
Some hospitals run a brief blood pressure check or a urine test on the same day, particularly for pregnancy scans. Bring any previous scan images or reports so the sonographer (the specialist who performs the scan) can compare results.
- Arrive with a full bladder if a transabdominal scan is planned.
- Empty your bladder if a transvaginal scan is planned.
- Wear comfortable, two-piece clothing so the abdomen or pelvic area is easy to access.
- Bring your referral letter, previous scan reports, and any relevant medical records.
- Remove any abdominal piercings if possible, as they can interfere with the image.
- You may be asked to undress from the waist down and cover with a drape for a transvaginal scan.
- A mild gel is applied to the skin for a transabdominal scan; it is cold but harmless.
- The sonographer moves the probe slowly and may press gently to get the best angle.
- The scan typically takes between fifteen and thirty minutes, though complex cases may take longer.
- You can ask the sonographer questions during the scan, but a full interpretation is usually provided by your doctor afterward.
Aftercare
Recovery after an obstetric/gynaecologic ultrasound is immediate. There is no anaesthetic (numbing medicine), no incision, and no recovery period. You can eat, drink, and drive as normal as soon as the scan is finished. If light spotting occurs after a transvaginal scan, it usually stops within a day and does not require treatment.
- You may resume all normal activities straight away.
- Wipe off any remaining gel from your skin with a tissue; it washes off easily.
- If you had a transvaginal scan and notice light spotting, a thin sanitary pad is sufficient; contact your doctor if bleeding is heavier than a normal period.
- Your doctor or clinic will explain when and how you will receive the written report, usually within a few hours to a few days.
- Follow-up depends entirely on what the scan finds. Some findings need no action at all; others may lead to additional imaging, blood tests, or a specialist referral.
- If you are pregnant, your obstetric team will schedule the next scan based on your gestational age and any findings from this one.
- Keep a copy of your scan images and report; they are useful if you consult a second doctor or travel abroad for further care.
Cost & What Determines It
The price of an obstetric/gynaecologic ultrasound varies considerably depending on where it is performed, how detailed the scan is, and what is included in the fee. A routine early-pregnancy scan at a local clinic costs far less than a detailed fetal anomaly scan with a specialist sonographer at a private hospital.
- Type of scan: a basic viability scan in early pregnancy is simpler and shorter than a full fetal anomaly scan or a 3D/4D scan that produces three-dimensional images.
- Specialist involvement: a scan read and reported by a maternal-fetal medicine specialist (a doctor who focuses on high-risk pregnancies) carries a higher fee than one reported by a general radiologist.
- Hospital class: private hospitals and internationally accredited centres charge more than public hospitals or independent clinics.
- Country of treatment: pricing differs significantly between countries, even for the same scan type.
- Complementary tests: blood tests such as combined first-trimester screening or non-invasive prenatal testing (NIPT) are often ordered alongside the scan and billed separately.
- Additional imaging: if the scan result is unclear and needs to be repeated, or if a second scan at a different angle is required, that may incur an extra charge.
- Urgency: an out-of-hours or emergency scan typically costs more than a routine appointment.
A hospital package for a pregnancy scan often includes the sonographer's time, use of the ultrasound machine, a printed or digital report, and sometimes a take-home image. Items that are commonly billed separately include the consultation fee if a specialist reviews the result face-to-face, any blood tests ordered at the same visit, and printed photographs or a recording of the scan.
BPJS Kesehatan does not cover medical procedures performed abroad, and most Indonesian private health insurance policies also exclude overseas treatment. Patients who travel abroad for a scan typically pay out of pocket or through an international private insurance plan that explicitly covers overseas diagnostics. Before travelling, request a written cost estimate from the hospital that itemises every component of the scan and any related consultations. This avoids unexpected charges when you arrive.
Frequently Asked Questions
Does an obstetric or gynaecologic ultrasound hurt?
This scan is generally painless. A handheld probe is moved gently over your abdomen, or, for a clearer view of the uterus and ovaries, a slim probe may be placed inside the vagina. The internal probe can feel slightly uncomfortable for some women, but it does not cause pain for most.
How do I prepare for a gynaecologic ultrasound? Do I need to fast?
Preparation depends on which type of scan your doctor orders. For an abdominal pelvic ultrasound, you are usually asked to drink water beforehand and arrive with a full bladder, because a full bladder helps the doctor see the uterus more clearly. For an internal (transvaginal) scan, you may be asked to empty your bladder first. Fasting is not normally required for either type.
How long does the scan take, and when will I get the results?
The scan itself usually takes between 15 and 30 minutes, though this can vary depending on what the doctor needs to check. In many clinics, the radiologist or obstetrician reviews the images on the same day and a written report is ready within a few hours, but some hospitals may ask you to return the following day to collect it.
How much does an obstetric or gynaecologic ultrasound cost?
The price varies depending on the type of scan ordered, whether it is a basic abdominal scan or a more detailed transvaginal or 3D/4D scan, the class of hospital or clinic you choose, and whether a specialist consultation is bundled in. For an accurate number, requesting a written cost estimate from the hospital before you book is the most reliable way to understand what you will pay.
