Prolapse and support
Images during bearing down can show how the bladder, uterus or vaginal vault, and back vaginal wall move. They may help clarify which structures are involved when the examination leaves a question.
PELVIC FLOOR · ASSESSMENT
Perineal ultrasound
An external scan that shows pelvic-floor support and movement. I use it to explore specific questions about prolapse, muscle injury, bowel symptoms or previous continence surgery, and to explain the findings with you.

HOW THE SCAN WORKS
The probe rests against the skin.
The perineum is the area between the vaginal opening and the anus. A covered ultrasound probe with gel is placed against this area. It stays outside the body for this scan.
Ultrasound uses sound waves to create images, without X-rays or ionising radiation. Watching while you relax, squeeze or bear down helps us see movement as well as structure.
This is also called transperineal or translabial ultrasound.
PREPARATION & THE APPOINTMENT
What to expect on the day.
Empty your bladder before this scan.
No special bowel preparation is usually needed. If another part of your assessment needs different preparation, we will explain this beforehand. Bring relevant operation reports or previous investigations if you have them.
Discuss the scan and get comfortable
I explain the question we are investigating and ask for your consent. You usually remove lower clothing in privacy and use a covering sheet. We find a suitable position, commonly lying on your back with knees bent. Tell me about tenderness, mobility difficulties or concerns about an examination. You can ask about a chaperone.
Look at rest and with movement
With gel between the covered probe and your skin, I obtain images at rest and may ask you to squeeze, cough or bear down. I will guide each step. You may feel pressure or cool gel. If it is uncomfortable, tell me so we can adjust; you can pause or stop at any point.
Discuss the findings
Afterwards you can wipe away the gel and get dressed. We discuss the relevant images, how they fit your symptoms and what to do next. The scan itself usually allows you to drive and carry on with normal activities; another procedure during the visit may involve different advice.
WHEN I SUGGEST IT
Start with a question the images can help answer.
The scan may be helpful when support symptoms are complex, bowel symptoms overlap with pelvic-floor changes, childbirth injury is suspected, or previous surgery needs closer assessment. It is one option within the consultation; many women can make a treatment plan from their history and examination without it.
WHAT IT CAN SHOW
Different symptoms raise different questions.
Difficulty emptying the bowel
Posterior-compartment imaging looks at the relationship between the rectum and the back vaginal wall. It can add information about a rectocele or other support changes when stool trapping or a blocked feeling is troublesome.
Muscles and bowel control
A separate question is whether the pelvic-floor muscles or the anal sphincter—the muscle ring controlling the back passage—show an injury. I use 3D or 4D views for selected muscle or sphincter assessments. Some symptoms need further targeted tests.
Previous continence surgery
Ultrasound can help locate a sling in relation to nearby structures when pain or difficulty passing urine needs investigation. The choice of tests depends on the symptoms, examination and operation history.
What do 2D, 3D and 4D mean?
2D shows a flat slice through the area. 3D records a volume that can be examined in different planes. 4D adds movement over time to the volume view. I choose the views that suit the question and explain any finding that matters to your care.
The images show anatomy and movement. They do not measure every aspect of bladder or bowel function or exclude all causes of symptoms. A bladder-function test, bowel-pressure test, colonoscopy or another assessment may answer a different question.
RESULTS & YOUR PLAN
Turn the findings into a useful next step.
I explain which findings are relevant, what remains uncertain and whether more assessment would help. A structural finding does not automatically mean surgery. Your symptoms, goals and treatment preferences remain central.
Support and rehabilitation
The plan may include a pessary, physiotherapy or bowel care. I value working with pelvic-health physiotherapists and other clinicians to address the different contributors to symptoms.
Further assessment or treatment
When appropriate, we can discuss surgical options, review previous treatment or arrange a test directed at a remaining question. Agree what happens next and how your response will be reviewed.
COMMON QUESTIONS
A few useful questions.
Is it the same as an internal vaginal or anal scan?
No. The perineal scan uses a probe against the outside skin. Internal vaginal and anal scans use different approaches. If another examination or test would help, I explain it separately and discuss your consent.
What if the area is sore or I feel anxious?
Please tell me beforehand. Pressure over a tender area can be uncomfortable even though the probe is external. We can discuss positioning, a chaperone and ways to make the assessment manageable. You can decline the scan or ask to pause or stop.
How much time should I allow?
The scanning itself is usually a short part of a broader consultation. Time varies with the question being assessed and the rest of the appointment. The practice can advise about your booking and fees beforehand.
What if the scan does not explain my symptoms?
Your symptoms still deserve care. We review the history and examination together and decide whether treatment, follow-up or a different test would help. A scan that shows no relevant abnormality does not rule out every bladder, bowel or pain condition.
YOUR NEXT STEP
Discuss your symptoms and the right assessment.
Book a medical consultation with me to review your concerns. We can decide whether perineal ultrasound would add useful information and discuss treatment together.
