Pelvic ultrasound examination, what to expect on the day - preparation, transabdominal + transvaginal views.

A practical patient guide to the pelvic ultrasound examination - how to prepare (full bladder for transabdominal, empty for transvaginal), what happens on the day, and how results are shared.

What it shows

What a pelvic ultrasound examination looks for.

Pelvic ultrasound answers a specific set of questions - uterine and endometrial anatomy, ovarian and adnexal appearance, and any focal pelvic pathology.

  • Uterine fibroids

    Number, size, location and impact on the endometrial cavity of leiomyomas.

  • Endometrial polyps

    Focal endometrial thickening or polypoid lesions, often better seen on transvaginal views.

  • Ovarian cysts

    Simple, haemorrhagic, dermoid or endometriotic cysts - characterised by IOTA descriptors.

  • Adnexal masses

    Solid, cystic or mixed lesions of the ovary, tube or paraovarian tissue.

  • Endometriosis signs

    Endometriomas, deep infiltrating nodules and reduced ovarian mobility on dynamic scanning.

  • Free fluid

    Physiological or pathological pelvic fluid in the pouch of Douglas.

  • Bladder wall assessment

    Bladder wall thickness, focal lesions and post-void residual volume.

  • Red flag: complex ovarian mass with ascites - urgent gynae-oncology

    A complex adnexal mass with ascites is an urgent gynae-oncology pathway, not a private outpatient wait.

Next steps

What can follow the scan.

The scan is the beginning of a plan, not the end of one. Depending on the finding, the sensible next step is usually one of the following.

  • Reassurance for benign findings

    Simple cysts and small fibroids often need nothing beyond explanation and interval reassurance.

  • MRI pelvis for characterisation

    For indeterminate adnexal masses, fibroid mapping or deep endometriosis staging.

  • Hysteroscopy for polyps

    Direct visualisation and biopsy or resection of endometrial polyps.

  • Gynaecology referral

    Consultant gynaecology opinion for symptomatic fibroids, cysts or bleeding.

  • Endometrial biopsy

    Pipelle or hysteroscopic biopsy for thick endometrium or postmenopausal bleeding.

  • Fertility investigation

    Antral follicle count, tubal patency and cycle-timed scans as part of a fertility work-up.

  • Multi-disciplinary team review

    Complex or suspicious findings are routed to a gynae-oncology MDT for planning.

  • Structured follow-up

    Interval scans at defined windows for cysts, fibroids or post-treatment surveillance.

Safety and eligibility

One of the safest tests in medicine.

Pelvic ultrasound is exceptionally safe - the practical points are preparation, the transvaginal probe, and where the scan’s limits are.

  • Painless, radiation-free

    Ultrasound uses sound waves - no needles, no radiation, no dye.

  • Warm gel used

    The contact gel for the transabdominal sweep is warmed, so the scan is comfortable from the first touch.

  • Transvaginal probe explained first

    A slim, disposable-sheathed probe. You choose to proceed - a chaperone is always offered.

  • Full bladder for TA, empty for TV

    Drink 1 litre of water an hour before if we ask for a transabdominal scan; empty the bladder before the transvaginal view.

  • Safe in pregnancy

    Pelvic ultrasound is the standard imaging test at any stage of pregnancy.

  • Menstruation is not a barrier

    Scans can be performed during a period; timing in the cycle is sometimes chosen for a specific question.

  • A normal scan is not a full clear

    A normal ultrasound doesn’t exclude every diagnosis - MRI or hysteroscopy may still be needed.

  • MRI sometimes follows on

    For deep endometriosis, complex fibroids or indeterminate adnexal masses, MRI is the next step.

  • Bring prior imaging and cycle dates

    Comparison against previous scans and knowing where you are in your cycle materially sharpens the report.

Red flags

Findings that change the pathway.

If any of the following appear on the scan or in your history, the sensible next step is an urgent specialist pathway - not a routine outpatient wait.

  • Complex ovarian mass

  • Ascites

  • Postmenopausal bleeding + thick endometrium

  • Suspected sarcoma

  • Rapidly growing fibroid

  • Adnexal torsion features

  • Pelvic infection with abscess

  • Ectopic pregnancy

  • Molar pregnancy

Reading your report

A pelvic ultrasound report can look intimidating. It isn’t.

Whatever the finding, the report keeps to the same four parts.

A quiet reminder

The report is written for your doctor, not for you - and that’s normal.

If you would like us to talk you through it before your follow-up, just ask.

Frequently asked

Everything we get asked about the pelvic ultrasound examination.

Quick answers on preparation, the transvaginal probe, cost, referrals and when a follow-up MRI or hysteroscopy come in.

  • What does a pelvic ultrasound examination show?

    The uterus, endometrial lining, ovaries, adnexa, bladder and pouch of Douglas. It characterises fibroids, endometrial thickening and polyps, ovarian and adnexal cysts and masses, signs of endometriosis, and free pelvic fluid.

  • How should I prepare?

    For the transabdominal view we ask you to drink one litre of water an hour before, so the bladder is comfortably full. You then empty the bladder before the transvaginal view, which needs an empty bladder for the best resolution.

  • Does the transvaginal probe hurt?

    It shouldn’t. The probe is slimmer than a speculum, is covered in a disposable sheath and lubricated. You choose to proceed and can stop the examination at any time. A chaperone is always offered.

  • Do I need a referral?

    Most clinics accept self-referral for a pelvic ultrasound.

  • How quickly will I get results?

    Findings are usually discussed immediately after the scan, with a formal written report from the reporting consultant the same day.

In practice, in London

Getting pelvic ultrasound examination sorted in London, without the guesswork

With pelvic ultrasound examination, the London question is usually about report turnaround and the radiologist reading it - not whether the scan is available. The wait for pelvic ultrasound examination on the NHS depends heavily on where you live and how urgently the referral is graded. Central and West London private clinics can normally book within a week, with imaging or a procedure slot to follow shortly after. It’s worth being honest about the reason for going private: usually it’s time, not a fundamentally different test.

A private pelvic ultrasound examination pathway in London usually looks like this: an initial consultation, any diagnostics booked at a nearby facility (most within Zone 1 or 2), and a written report sent to you and your GP within a few days. The consultants we work with hold NHS posts alongside their private lists, which keeps the standards consistent across both settings. For pelvic ultrasound examination specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.

We’re careful about what a private pathway for pelvic ultrasound examination can and can’t promise. It can compress a wait, put you in front of a subspecialist quickly, and get a proper report in your hands within a week. It can’t rewrite what the imaging or the bloods say. Setting that expectation up front tends to make the whole experience less stressful.
