Dynamic hernia ultrasound • London & St Albans
Private hernia ultrasound scan
A focused, radiation-free ultrasound assessment for a suspected groin or abdominal-wall hernia. The examination is performed at rest and dynamically—often while you cough, strain or stand—to identify a fascial defect, measure the hernia neck, assess its contents and determine whether it is reducible.
- No GP referral required
- Dynamic cough and Valsalva assessment
- Groin and abdominal-wall hernias
- Written report and images
Direct answer
Can ultrasound detect a hernia?
Yes. Dynamic ultrasound is commonly used to assess suspected superficial groin and abdominal-wall hernias. It can show a defect in the fascia and the movement of fat, omentum or bowel through that defect. Because the scan is performed in real time, the practitioner can examine the area while you cough, strain or stand to reproduce an intermittent lump.
The scan can document the hernia’s site, type, defect or neck size, contents, maximal protrusion and reducibility. It may also identify another visible cause of a lump or pain, such as a lymph node, lipoma, fluid collection or hydrocele.
A targeted dynamic ultrasound of the clinically relevant hernia area, with measurements, images and a written report. Contact the clinic before booking if you need several separate sites, bilateral groins, detailed scar mapping or an additional scrotal examination.

Hernias assessed
Which types of hernia can ultrasound examine?
The examination is targeted to the area of symptoms. Dynamic manoeuvres and positional changes are used when clinically appropriate.
Inguinal hernia
Assessment of the inguinal canal for a direct or indirect hernia, including the neck, contents, reducibility and possible extension towards the scrotum.
Femoral hernia
Evaluation below the inguinal ligament near the femoral canal. Femoral hernias may be small and can carry a greater risk of complications.
Umbilical or para-umbilical
Assessment at or next to the navel, documenting the defect, protruding tissue and whether the hernia reduces at rest or with gentle pressure.
Epigastric or ventral hernia
Targeted scanning of a midline or other abdominal-wall bulge, including small fat-containing defects that may appear mainly with strain.
Incisional hernia
Assessment along a previous surgical scar to identify one or more defects and document their relationship to scar tissue or visible mesh.
Spigelian or lateral-wall hernia
Evaluation of a suspected lateral abdominal-wall defect, which can be deeper or less obvious and may require standing or Valsalva to demonstrate.
What the sonographer records
What does a dynamic hernia ultrasound evaluate?
The report combines anatomical measurements with real-time behaviour during rest, cough, strain, standing and gentle probe pressure when tolerated.
Site and type
The practitioner identifies the exact anatomical location and, where possible, classifies the hernia as inguinal, femoral, umbilical, ventral, incisional or another abdominal-wall type.
Defect or neck size
The opening in the abdominal wall or inguinal canal is measured because its size and position can assist clinical or surgical decision-making.
Hernia contents
The scan records whether the protrusion contains preperitoneal fat, omentum, bowel or another visible structure.
Dynamic protrusion
The maximal size of the hernia is assessed during cough, Valsalva or standing and compared with the appearance at rest.
Reducibility
The practitioner notes whether the protruding tissue returns spontaneously or with position and gentle pressure, or remains non-reducible.
Alternative findings
Accessible surrounding tissues may be reviewed for another explanation such as a lymph node, lipoma, hydrocele, fluid collection or focal soft-tissue abnormality.

Reasons to book
When might you need a hernia scan?
- A groin, abdominal-wall or belly-button lump that appears when standing, coughing or lifting.
- Pain, pressure, pulling or a dragging sensation in the groin or abdomen.
- A bulge that becomes larger with strain and reduces or disappears when lying down.
- Persistent localised discomfort despite an uncertain or normal physical examination.
- Swelling or pain at a previous surgical scar, including concern about an incisional hernia.
- Pre-operative assessment of a known or suspected superficial hernia.
Before your appointment
How to prepare for a hernia ultrasound
Preparation is simple. The booking confirmation should take priority when it gives instructions specific to your examination.
No routine fasting
Fasting is not usually required for a targeted groin or abdominal-wall hernia scan. Avoiding a very heavy meal immediately beforehand may improve comfort for an umbilical or upper abdominal-wall examination.
Wear suitable clothing
Choose loose clothing that allows access to the groin, navel, scar or abdominal-wall area. A gown or drape can be provided when needed.
Expect movement
You may be asked to cough, strain, change position or stand so that an intermittent bulge can be reproduced and assessed dynamically.
Bring useful records
Bring any referral letter, previous imaging, operation note or information about when the lump appears, what triggers it and whether it reduces.
Your appointment
What happens during the scan?
The examination is non-invasive and usually takes around 20–30 minutes.
- 1
Clinical discussion
The practitioner confirms the location of the lump or pain, when it appears, relevant surgery, previous imaging and any symptoms that may require urgent medical review.
- 2
Ultrasound at rest
You lie on the examination couch while gel is applied. The area and relevant anatomical landmarks are scanned in multiple planes.
- 3
Dynamic manoeuvres
You may be asked to cough, strain, perform Valsalva or stand. Real-time images and cine loops document any protrusion and its behaviour.
- 4
Measurements and report
The defect, hernia neck, contents, maximal protrusion and reducibility are recorded. The main observations can usually be discussed after the scan, followed by a written report with images.
Understanding the outcome
Results, limitations and next steps
Ultrasound findings are interpreted alongside your symptoms and clinical examination. The report will state whether a hernia was demonstrated and describe any relevant limitations.
What the report may describe
- No hernia demonstrated during rest and dynamic manoeuvres.
- The side and type of hernia, such as direct or indirect inguinal.
- The size of the defect or neck and maximal protrusion.
- Whether the contents are fat, omentum, bowel or another structure.
- Whether the hernia is reducible, partially reducible or non-reducible.
- An alternative visible cause for the lump or pain.
What may be recommended
- Review by your GP, general surgeon or another appropriate specialist.
- Urgent clinical assessment if symptoms suggest incarceration, obstruction or strangulation.
- CT for complex, recurrent or deeper abdominal and pelvic assessment.
- MRI for an occult groin hernia or suspected musculoskeletal inguinal disruption.
- A dedicated scrotal, soft-tissue or musculoskeletal ultrasound when another condition is suspected.
Choosing the right imaging
Hernia ultrasound, CT or MRI?
The best test depends on the location, complexity and clinical question.
Dynamic ultrasound
Often the first imaging test for a superficial inguinal, femoral, umbilical or abdominal-wall hernia. It provides real-time cough, strain and standing assessment without radiation.
CT scan
Provides a wider overview of the abdomen and pelvis and may be helpful for complex, recurrent, obstructed or deep hernias, or for surgical planning. It uses ionising radiation.
MRI scan
Offers detailed soft-tissue imaging without radiation and may help with an occult groin hernia or sports-related inguinal disruption when ultrasound is inconclusive.

Questions answered
Hernia ultrasound FAQs
These answers provide general information. Your practitioner will interpret the scan in relation to your history, symptoms and clinical examination.
Can an ultrasound detect a hernia?
Yes. Dynamic ultrasound can demonstrate many inguinal, femoral, umbilical, para-umbilical, epigastric, ventral and incisional hernias. Scanning while you cough, strain or stand is particularly useful when a lump is intermittent or not visible at rest.
What does a hernia ultrasound assess?
The scan looks for a defect in the abdominal wall or inguinal canal, measures the neck or opening, identifies the hernia contents such as fat, omentum or bowel, and assesses movement, tenderness and reducibility during dynamic manoeuvres.
Can ultrasound miss a hernia?
A small, deep or intermittent hernia may not protrude during the examination. Detection can also be limited by body habitus, pain-limited straining or a deeply located defect. CT or MRI may be recommended when clinical concern remains despite an inconclusive ultrasound.
Do I need to fast before a hernia ultrasound?
Fasting is not usually required for a targeted groin or abdominal-wall hernia scan. Wear comfortable clothing that allows access to the area. For an umbilical or upper abdominal-wall concern, avoiding a heavy meal immediately beforehand may improve comfort.
How long does a hernia ultrasound take?
A targeted hernia ultrasound usually takes about 20 to 30 minutes. It may take longer when more than one site requires assessment, the hernia is difficult to reproduce, or detailed post-operative scar mapping is needed.
Is a hernia ultrasound painful?
The examination is non-invasive and usually comfortable. The practitioner may apply gentle probe pressure over the area and ask you to cough, strain or stand. Pressure over a tender lump can cause brief discomfort.
Do I need a GP referral?
No. PrivateSono accepts self-referrals for a private hernia ultrasound. Bring any GP or specialist letter, previous scan or operation report when available because this can help tailor the examination.
When will I receive the results?
The practitioner can usually discuss the main observations after the scan. A structured written report with relevant images is then provided for you to share with your GP, surgeon or other clinician.
What happens if no hernia is found?
The report may describe an alternative visible cause of the lump or pain, such as a lymph node, lipoma, fluid collection, hydrocele or soft-tissue abnormality. Further clinical assessment, a dedicated scan, CT or MRI may be advised when appropriate.
When is a suspected hernia an emergency?
Seek urgent medical assessment rather than waiting for a routine scan if a lump becomes suddenly very painful, firm or irreducible, particularly with vomiting, abdominal swelling, fever, skin colour change or inability to pass stool or wind.
