Pelvic ultrasound, transvaginal or transabdominal ultrasound of uterus, ovaries, bladder and pelvic organs.

A pelvic ultrasound scan is a radiation-free imaging test using transvaginal + transabdominal probes to assess the uterus, ovaries, adnexae, bladder and (in men) prostate. First-line for pelvic pain, abnormal bleeding, subfertility, fibroids and cysts.

Key facts

  • 01

    Transabdominal + transvaginal

    Ultrasound of the pelvic organs - uterus, ovaries, adnexae, bladder and (in men) prostate - combining both probe approaches.

  • 02

    Radiation-free

    Uses sound waves only. Safe in pregnancy, safe to repeat, no dye and no needles.

  • 03

    20–30 minute test

    Straightforward slot: gel, sweep, Doppler, done. You dress and leave the same visit.

  • 04

    Consultant sonographer performs

    The person scanning you is also the person reading the images - no hand-off, no lost detail.

  • 05

    Doppler for adnexal flow

    Colour and spectral Doppler assesses ovarian and adnexal vascularity - key for characterising cysts and masses.

  • 06

    Complements MRI pelvis

    First-line for most pelvic symptoms; MRI pelvis follows when characterisation, staging or endometriosis mapping is needed.

Indicative pricing

What a private pelvic ultrasound costs in London.

Indicative ranges across UK private providers.

In short

£220–£420, with findings usually the same day.

Scan type Indicative range
Standard pelvic ultrasound (transabdominal + transvaginal) £220–£420
Transabdominal pelvic ultrasound only £180–£320
Pelvic ultrasound + gynaecology consultation £450–£850
Pelvic ultrasound + endometrial biopsy £550–£950
Follow-up / surveillance pelvic ultrasound £200–£380
Urgent same-week pelvic ultrasound £350–£700

Prices vary by clinic, whether a same-visit consultant gynaecology opinion is included, and whether an endometrial biopsy is added.

The problem

A pelvic ultrasound is only as good as who reports it.

Adnexal masses, endometrial findings and fibroid mapping are interpretation calls. It is worth asking for a consultant sonographer with a gynaecology subspecialty interest - not a generalist.

  • Ovarian cyst on a prior scan?

    It is characterised against IOTA descriptors - reassure, follow up or refer.

  • Subfertility work-up?

    Antral follicle count, uterine cavity and pelvis, folded into a fertility pathway.

What it shows

When a pelvic ultrasound is the right test.

Pelvic ultrasound answers specific questions about the uterus, endometrium, ovaries and adnexae. These are the most common presentations and findings.

  • Uterine fibroids

    Size, number and position of fibroids - submucosal, intramural, subserosal - that explain heavy bleeding or pressure symptoms.

  • Endometrial thickness / polyps

    Measures endometrial thickness and identifies polyps - first-line for abnormal or postmenopausal bleeding.

  • Ovarian cysts

    Simple, haemorrhagic, dermoid and complex cysts - characterised using IOTA descriptors and Doppler flow.

  • Adnexal masses (IOTA)

    IOTA Simple Rules classify adnexal masses as benign, malignant or inconclusive, guiding the next step.

  • Endometrioma / endometriosis signs

    Endometriomas, deep infiltrating nodules and adhesions - MRI or specialist scan may extend the map.

  • Pelvic free fluid

    Small physiological fluid vs pathological ascites - a red-flag context, not a diagnosis in itself.

  • Bladder wall assessment

    Bladder wall thickness, residual volume, mass or diverticulum - often incidentally picked up on pelvic ultrasound.

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

    A complex ovarian mass alongside ascites is an urgent gynae-oncology pathway, not a private waiting-room finding.

Next steps

What follows a pelvic ultrasound.

The scan is the beginning, not the answer. Where each finding goes next.

  • Reassurance for benign findings

    Simple cysts, small fibroids and normal endometrium in the right context need explanation, not intervention.

  • MRI pelvis for characterisation

    Complex adnexal masses, deep endometriosis and fibroid mapping benefit from MRI’s soft-tissue contrast.

  • Hysteroscopy for polyps

    Endometrial polyps and submucosal fibroids are seen - and often removed - at hysteroscopy.

  • Gynaecology referral for fibroids / cysts

    Symptomatic fibroids and persistent or complex cysts are discussed with a consultant gynaecologist.

  • Endometrial biopsy

    A thickened endometrium or postmenopausal bleeding is sampled - Pipelle in clinic or at hysteroscopy.

  • Fertility investigation

    Ultrasound is a cornerstone of subfertility work-up - antral follicle count, uterine cavity and tubal patency planning.

  • Multi-disciplinary team review

    Suspicious findings are discussed at gynae-oncology MDT before onward decisions.

  • Structured follow-up

    Simple cysts and small fibroids are followed at defined intervals - no surprises, no drift.

Red flags

The findings that change the pathway.

Most pelvic ultrasounds are reassuring. These are the findings that shift the answer from private waiting room to urgent pathway.

  • Complex ovarian mass

    Multi-locular solid mass with vascularised solid components - urgent gynae-oncology referral.

  • Ascites

    Free intra-abdominal fluid outside a physiological context - investigate urgently.

  • Postmenopausal bleeding with thickened endometrium

    Endometrial thickness >4 mm after menopause with bleeding - biopsy is the standard next step.

  • Suspected sarcoma

    A rapidly growing uterine mass with atypical features raises the (rare) possibility of leiomyosarcoma.

  • Rapidly growing fibroid

    Documented rapid interval growth - especially postmenopausally - needs urgent gynaecology review.

  • Adnexal torsion features

    Acute pelvic pain with an enlarged, poorly vascularised ovary is a surgical emergency - A&E, not a private slot.

  • Pelvic infection with abscess

    A tubo-ovarian abscess needs urgent gynaecology admission and IV antibiotics.

  • Ectopic pregnancy

    A positive pregnancy test with an empty uterus and adnexal features - same-day early pregnancy unit assessment.

  • Molar pregnancy

    The classic snowstorm appearance with markedly raised hCG - urgent gestational trophoblastic disease pathway.

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 it explained before your follow-up, ask your GP or specialist.

Frequently asked

Common questions about pelvic ultrasound.

Quick answers on what it shows, transvaginal vs transabdominal, safety in pregnancy, and when MRI pelvis follows.

  • What does a pelvic ultrasound show?

    The uterus, endometrium, ovaries, adnexae, pouch of Douglas and bladder. In men, the prostate and bladder. It is first-line for pelvic pain, abnormal bleeding, subfertility, fibroids and ovarian cysts.

  • Do I need both transabdominal and transvaginal scans?

    In most gynaecology work-ups, yes. Transabdominal gives the overview through a full bladder; transvaginal - with an empty bladder - gives the closest, highest-resolution look at the uterus and ovaries. Transvaginal is optional and always your choice.

  • Is a pelvic ultrasound safe in pregnancy?

    Entirely safe. Ultrasound uses sound waves, not radiation, and is the standard imaging test at every stage of pregnancy.

  • How quickly will I get results?

    Findings are discussed with you immediately after the scan, with a same-day written report from the consultant sonographer.

  • When would I need an MRI pelvis instead?

    MRI pelvis follows pelvic ultrasound when a mass needs full characterisation, endometriosis needs mapping, or fibroids need pre-treatment planning. Ultrasound comes first; MRI extends the answer.

  • What is IOTA and why does it matter?

    IOTA - International Ovarian Tumour Analysis - is the validated framework for classifying adnexal masses on ultrasound. It sorts masses into benign, malignant or inconclusive, and shapes whether you need reassurance, MRI or urgent gynae-oncology referral.

In practice, in London

Booking pelvic ultrasound privately in London - what actually happens

With pelvic ultrasound, the London question is usually about report turnaround and the radiologist reading it - not whether the scan is available. Public provision for pelvic ultrasound is competent but constrained by capacity. Private London clinics tend to have shorter diaries and longer appointment slots, so you get the same specialists with more time. For people who’ve been going round in circles with primary care, that first proper conversation is often what shifts things.

A private pelvic ultrasound 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. For pelvic ultrasound specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.

The value is knowing which consultant reads this particular presentation best, which unit turns reports around fastest, and which pathway won’t hit a dead end if the findings point somewhere unexpected.
