A prostate ultrasound scan — usually a transrectal ultrasound (TRUS) — images the prostate gland to check its size, structure and blood flow, and is available privately in London and Surrey from £215 with same-day results.

What Is a Prostate Ultrasound?

A prostate ultrasound, often referred to as a transrectal ultrasound (TRUS), is a diagnostic imaging test that uses high-frequency sound waves to visualise the prostate gland and the tissue around it. According to Cancer Research UK:

“A prostate ultrasound scan can show changes in your prostate, including abnormal growths.”

At Phoenix Ultrasound, an ultrasound scan for prostate assessment builds a picture of the gland’s size and internal structure, and — when performed transrectally with colour Doppler — its blood flow too, helping identify patterns linked to enlargement, inflammation or suspicious lesions.

When and Why We Use a Prostate Ultrasound

A prostate ultrasound scan is most often requested alongside other clinical findings, rather than as a stand-alone first step. The table below covers the main reasons men are referred, or self-refer, for one.

Reason for the scan What it may indicate
Elevated PSA on a blood test Possible enlargement, inflammation or, less commonly, cancer
Abnormal digital rectal exam (DRE) A felt nodule or irregularity needing imaging follow-up
Urinary symptoms Difficulty voiding, frequency, weak stream or incomplete emptying
Suspected BPH or prostatitis Enlargement or inflammation needing confirmation
Biopsy guidance or monitoring Precise targeting for a biopsy, or tracking a known condition

 

What the Scan Includes

Most appointments combine two views. A transabdominal pass, through the lower abdomen with a full bladder, gives an initial look at the prostate and bladder. Where more detail is needed, a transrectal (TRUS) probe is used for close-up images of the gland itself — this is the approach most private clinics mean when they describe an “ultrasound scan for prostate” assessment.

Approach How it’s done Best for
Transabdominal Through the lower abdomen, bladder full A first, non-invasive overview
Transrectal (TRUS) Small probe inserted into the rectum Detailed prostate size, structure and blood flow

 

The scan itself typically takes 15-20 minutes; allow 30-60 minutes for the full appointment, including check-in and a brief discussion of what was seen.

What to Expect on the Day

You’ll arrive at the clinic and change into a gown from the waist down. A trained sonographer or radiologist explains the procedure and asks you to sign consent before any internal scanning. For the transabdominal part, drink about a litre of water an hour beforehand and avoid the toilet, so you arrive with a comfortably full bladder; you’ll then be asked to empty it before the transrectal portion. You’ll usually lie on your side with your knees drawn up while the probe, covered with a protective sheath and gel, is gently inserted. Most men feel pressure or discomfort rather than sharp pain — this varies between individuals but is brief. Afterwards you can resume normal activities straight away, with a verbal summary given on the day and a full written report usually following within 24 hours.

Who Performs the Scan & Equipment Used

Your scan is carried out by an HCPC-registered sonographer or a consultant radiologist with dedicated ultrasound training, using high-resolution equipment with transrectal probe capability built for pelvic and prostate imaging. The clinic operates under CQC registration, following recognised governance protocols for diagnostic imaging.

Conditions Detected & Diagnostic Value

Condition What the scan assesses
Benign prostatic hyperplasia (BPH) Gland enlargement linked to urinary symptoms
Prostate cancer suspicion Suspicious nodules or lesions, especially with raised PSA or MRI findings
Prostatitis Signs of inflammation or infection, though usually needs further tests
Calcifications or cysts Structural changes within the gland
Biopsy planning Ultrasound guidance for accurate needle placement

 

Safety and Limitations

This scan is a diagnostic imaging tool, not a substitute for specialist assessment. Where cancer is suspected, a urologist will usually still need a biopsy to reach a definite diagnosis. A prostate ultrasound uses no ionising radiation, making it a safer alternative to X-ray-based imaging. The transrectal probe can cause brief discomfort — it isn’t entirely non-invasive — and image quality can be affected by prostate size, calcification or individual anatomy. Importantly, a clear scan (or even a clear biopsy) doesn’t fully rule out disease, especially prostate cancer, so your clinician may still recommend ongoing monitoring or further imaging.

Pricing & Booking

Phoenix Ultrasound offers three levels of prostate ultrasound scan london patients can choose from, depending on how much detail your clinician needs:

Scan type What’s included Price
Prostate & Bladder Ultrasound Transabdominal/transrectal assessment of prostate size, structure and bladder £215
Prostate Transrectal Colour Doppler Detailed TRUS plus colour Doppler blood-flow assessment £365
Transrectal SWE & Colour Doppler (multiparametric) Doppler scan plus Shear Wave Elastography for tissue stiffness £465

 

Note: the multiparametric option combines ultrasound-based Doppler and elastography techniques — it is not the same test as a multiparametric MRI (mpMRI), which some men have as a separate step in their diagnostic pathway.

No GP referral is needed — self-referral is accepted — and same-day or next-day appointments are usually available. Flexible payment, including interest-free instalments via Klarna, is offered on all scans.

Locations

Appointments run at two Phoenix Ultrasound clinics: Central London, at 1 Portpool Lane, Holborn, EC1N 7UU, and Banstead, Surrey, at 63 Nork Way, SM7 1HL. The team can be reached by phone and text seven days a week, from 7am to 10pm.
