Second opinions and complex referrals
A second opinionbefore you decide
Asking for a second opinion before major cancer surgery isn't indecision. It's good judgement. Mr Sri reviews your scans, biopsy and proposed treatment, and gives you a frank, independent view, in person or by video.
4.99 / 5Doctify ratingOutstanding Patient Experience 2026
Does this sound like you?
Patients come having been seen elsewhere, referred by their GP or consultant, or having found the practice themselves. All are equally welcome, and no GP referral is needed.
I've been told my whole kidney needs to come out
Find out whether kidney-sparing surgery is realistic, even for a complex or central tumour.
I've been advised to monitor a kidney mass
Understand whether surveillance is right for you, or whether treatment now makes more sense.
I've been offered radiotherapy for prostate cancer
Hear the surgical option explained honestly, with its benefits and side effects, before you commit.
I'm not sure which prostate operation is best
Retzius-sparing or standard nerve-sparing: which suits your cancer and anatomy, and why.
My prostate cancer is high-risk
An experienced view on surgery for higher-risk and locally advanced disease, including lymph node removal.
I've had previous abdominal surgery
Reaching the kidney from behind avoids scarring from past operations, which can change what's possible.
A second opinion isn't a sales pitch for surgery. Many patients leave reassured that the treatment they were offered is the right one, and continue their care where they started.
Why patients are referred to Mr Sri
High volume robotic surgeon with >225 robotic kidney & prostate procedures per year.
- Surgery from behind as standardOne of a small group of surgeons in Europe who routinely use retroperitoneal robotic partial nephrectomy, which he introduced to South West London.
- Complex tumours acceptedIncluding central, hilar, posterior and deeply buried tumours declined for kidney-sparing surgery elsewhere. Positive margins in under 1%.
- Told to remove the kidney, or to waitFor patients advised to have radical nephrectomy or surveillance who want to know whether keeping the kidney is realistic.
- Previous abdominal surgeryThe approach from behind avoids the abdominal cavity and any scarring or adhesions from past operations.
- A single kidneyWhen every bit of kidney function matters, preserving it is the priority, however demanding the surgery.
- Higher body weightGoing in from behind gives more direct access to the kidney without moving the bowel.
Principal Investigator at St George's for the national PARTIAL trial of partial versus radical nephrectomy for higher-risk kidney tumours.
What a high RENAL score means →
- A high-volume robotic surgeonOver 225 robotic operations a year, with no conversions to open surgery. Surgeon volume is one of the strongest predictors of results.
- Technique chosen for youPerforms both Retzius-sparing and standard nerve-sparing prostatectomy, and recommends the one that fits your cancer and anatomy.
- High-risk and locally advanced cancerPrincipal Investigator for the ELIPSE trial, for higher-risk disease such as stage T3, PSA above 20 or Gleason 8 to 10.
- Regional cancer leadUrology Cancer Lead at St George's, the tertiary centre for complex prostate cancer across South West London.
- A trainer of surgeonsLeads the RCS-accredited robotic urology fellowship at St George's, training the next generation of robotic surgeons.
- Before radiotherapyA clear comparison of surgery and your radiotherapy plan, including the side effects of each, before you commit.
Also Principal Investigator at St George's for PART, the national trial of focal therapy for localised prostate cancer.

Mr Sri reviews everything
He looks at your scans themselves, not just the reports, along with your biopsy results and the plan you've been offered.
An unhurried consultation
In person at one of four London hospitals, or by video. He explains what he sees, every realistic option, and his recommendation.
A clear written summary
A letter for you and your doctors setting out his view. Whether you continue where you are or transfer your care is entirely your choice.
Helping answer the hardest questions
Mr Sri is Principal Investigator at St George's for national trials on exactly the decisions second opinions are about.
PARTIAL
Keep part of the kidney, or remove all of it, for higher-risk tumours?
ELIPSE
Does removing the lymph nodes help men with high-risk prostate cancer?
PART
Can treating only the cancer with focal therapy work as well, with fewer side effects?

Second opinions: your questions answered
Will my current consultant mind?
No. Second opinions are a normal and respected part of cancer care, and most consultants welcome them. You don't need their permission, and you can stay under their care throughout.
Do I need a GP referral?
Not for a self-pay consultation. If you're using health insurance, your insurer may ask for a GP or specialist referral and a pre-authorisation code, so check with them first.
Can I have a second opinion by video?
Yes. Video consultations work well for reviewing scans and results, and are popular with patients outside London. If an examination is needed, it can be arranged afterwards.
Will I have to move my treatment?
No. You'll receive a written summary to share with your team. Whether you continue where you are or have treatment with Mr Sri is entirely your decision.
How much does it cost?
A new self-pay consultation is £350 and a follow-up is £250. Any extra tests are quoted separately. All major insurers are accepted.
Four London hospitals
Wimbledon, Kingston, Marylebone and Harley Street. Video consultations also available. Self-pay consultations £350 new, £250 follow-up, and all major insurers accepted.
