Prostate biopsy, MRI-targeted transperineal biopsy for suspected prostate cancer.
A rising PSA and a Likert 4 or 5 lesion on your mpMRI is a difficult letter to open — but the biopsy itself, done properly, is a very different experience to the transrectal one your father may remember. In UK private practice today it is transperineal, MRI‑fused, done under local or general anaesthetic in a day unit, with Gleason and ISUP grades back inside a fortnight.

Key facts
- 01
The modern UK standard: transperineal, MRI‑fused
Sepsis rates below 1 in 500, targeted at the exact Likert 4–5 lesion your mpMRI flagged — a very different experience to the transrectal biopsy your father may remember.
- 02
mpMRI first, then targeted cores
A Likert 4–5 lesion on multiparametric MRI is fused with live ultrasound so the biopsy actually samples the suspicious area, alongside a systematic map of the gland.
- 03
Ultrasound-guided
Real-time transrectal ultrasound guides the needle through the perineal skin into the prostate.
- 04
MRI-fusion targeting
The prior mpMRI is fused with live ultrasound so Likert 4–5 lesions are sampled precisely.
- 05
Systematic + targeted
A combination of targeted cores from MRI lesions and systematic cores across the gland.
- 06
Same-day discharge
Most men go home the same day, with pathology reported over the following 5–10 days.
Diagnosis pathway

Pathology and plan
- 01
Before
Urology consultation
A consultant urologist reviews your PSA, symptoms, DRE and family history, and confirms biopsy is the right next step.
- 02
Before
mpMRI + Likert scoring
A multiparametric prostate MRI is reported with a Likert score (1–5). Likert 4–5 lesions are the biopsy targets.
- 03
Before
Antibiotic cover
A short course of prophylactic antibiotics is given around the procedure to reduce infection risk.
- 04
On the day
Local or general anaesthetic
You are prepared in theatre or a procedure room, with either a local perineal block or a short general anaesthetic.
- 05
On the day
Transperineal biopsy
A transrectal ultrasound probe guides the needle through the perineum. Targeted and systematic cores are taken.
- 06
After
Pathology review (Gleason / ISUP)
Cores are reviewed by a specialist uropathologist and reported using Gleason grade and ISUP grade group.
- 07
After
Structured urology plan
Your consultant urologist explains findings and, where cancer is confirmed, arranges MDT review and a treatment plan.
What it shows
What a prostate biopsy report actually tells you.
Each field on the pathology report has a specific meaning — and specific consequences for the treatment plan.
-
Gleason grade
The classic pathology grade (3+3 to 5+5) describing how aggressive the cancer looks under the microscope.
-
ISUP grade group
The modern grade group (1–5) that maps Gleason score onto prognosis and guides treatment.
-
Cores positive / total
How many cores contain cancer, out of the total taken — a marker of disease volume across the gland.
-
Cancer core length (mm)
The length of cancer within each positive core in millimetres — used to gauge tumour burden.
-
Perineural invasion
Cancer cells tracking along nerves within the prostate — an adverse pathology feature.
-
Cribriform pattern
A specific architectural pattern of Gleason 4 associated with higher risk of progression.
-
Extraprostatic extension flag
Suggestion of cancer extending beyond the prostate capsule — a driver of staging and treatment choice.
-
Red flag: Gleason 8+ — urgent MDT
ISUP 4–5 disease triggers urgent multi-disciplinary team review and rapid staging imaging.
Treatment options
What follows a biopsy-proven diagnosis.
Treatment is chosen by MDT, tailored to Gleason/ISUP grade, disease volume, PSA and staging.
-
Active surveillance (Gleason 6, low volume)
Close monitoring with repeat PSA, MRI and biopsy for low-risk disease — avoiding overtreatment.
-
Focal therapy
Selective ablation (HIFU or cryotherapy) of an index lesion, sparing the rest of the gland.
-
Radical prostatectomy
Surgical removal of the whole prostate — most often robot-assisted (RALP) — for localised disease.
-
External beam radiotherapy
Curative-intent radiotherapy — typically hypofractionated or SBRT — with or without hormone therapy.
-
Brachytherapy
Radioactive seed or high-dose-rate implants placed directly into the prostate as a targeted radiation option.
-
Androgen deprivation therapy
Hormone therapy to suppress testosterone — used with radiotherapy in intermediate/high-risk or advanced disease.
-
Structured urology + oncology follow-up
Scheduled PSA, imaging and clinic review across a shared urology and oncology pathway.
-
Multi-disciplinary team review
Every biopsy-proven cancer is discussed at MDT — urology, oncology, radiology and pathology together.
Red flags
When something needs urgent attention.
Adverse pathology features on the report — and post-procedure symptoms that mean urgent review, not a wait-and-see.
-
Gleason 8+ / ISUP 4–5
High-grade disease — triggers urgent MDT, staging and rapid treatment planning.
-
Cribriform pattern
An adverse Gleason 4 architecture linked to higher risk of progression and recurrence.
-
Perineural invasion
Cancer tracking along nerves — an adverse pathology feature that may influence treatment intensity.
-
Extraprostatic extension
Suggestion of disease beyond the capsule — upstages the cancer and shapes surgical or radiation planning.
-
Rising PSA post-biopsy
A rising PSA on repeat testing after negative biopsy warrants re-imaging and repeat sampling.
-
Post-biopsy sepsis
Fever, rigors or feeling systemically unwell after biopsy — a medical emergency, present to A&E.
-
Post-biopsy urinary retention
Inability to pass urine after the procedure — needs urgent urology or A&E review.
-
Post-biopsy rectal bleeding
Small amounts of blood are expected; heavy or persistent bleeding needs urgent review.
-
Anaesthetic complication
Any concerning cardiovascular or respiratory symptoms after a general anaesthetic — call 999.
Frequently asked
Everything we get asked about prostate biopsy.
Quick answers on technique, anaesthetic, results, risks and what happens if cancer is found.
-
How soon can I get a private prostate biopsy in London after an abnormal MRI?
Most patients are booked into a London day unit within one to two weeks of a Likert 4–5 mpMRI, sometimes sooner. Gleason and ISUP grades follow 5–10 working days after the biopsy, and your consultant urologist walks you through the report in a dedicated review — with a urology MDT behind any confirmed cancer.
-
Why is transperineal preferred over transrectal biopsy?
Transperineal biopsy passes through cleaned skin rather than through the rectum, which materially lowers the risk of post-biopsy sepsis and provides better access to the anterior prostate.
-
Is the biopsy done under local or general anaesthetic?
Both are routine. Local anaesthetic transperineal biopsy is well tolerated and avoids a general; a short general anaesthetic is often chosen for patient comfort or when more cores are planned.
-
How long until I get the pathology report?
Pathology reporting — Gleason grade and ISUP grade group — typically takes 5–10 working days. Your consultant urologist will book a review appointment to discuss the results.
-
What are the main risks of prostate biopsy?
Short-term blood in urine, semen and stool is expected. The important risks to know about are post-biopsy sepsis (fever, feeling systemically unwell), urinary retention, and heavier rectal or urinary bleeding — any of these need urgent review.
-
What happens if cancer is found?
Every biopsy-proven prostate cancer is discussed at a urology multi-disciplinary team meeting. The plan is tailored to your Gleason/ISUP grade, disease volume, PSA and staging imaging — from active surveillance to focal therapy, surgery, radiotherapy or hormone therapy.

In practice, in London
Booking prostate biopsy privately in London — what actually happens
With prostate biopsy, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. Public provision for prostate biopsy 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 prostate biopsy 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 prostate biopsy 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 prostate biopsy 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.
