Outstanding Patient Experience 2026Doctify award
Consultant Urological Surgeon, London
Mr Denosshan Sri
MA Cantab, MB BChir, FRCS Urol
A high-volume robotic surgeon specialising in kidney and prostate cancer, minimally invasive urology and complex reconstruction. Consultant at St George's University Hospital and Kingston Hospital, specialising in kidney preservation surgery for kidney cancer and nerve sparing robotic prostatectomy for prostate cancer.
From Cambridge to robotic cancer surgery
Mr Sri graduated from the University of Cambridge with a double first in Medicine and was awarded a Distinction. He trained in urology across South West London, then completed a highly competitive Royal College of Surgeons accredited post-CCT fellowship in robotic surgery at Frimley Park Hospital, one of the UK's leading robotic centres. He was appointed Consultant Urologist at St George's University Hospital in October 2021, and a split site post at Kingston Hospital in October 2024.
His focus is robotic surgery for kidney and prostate cancer: nerve-sparing robotic prostatectomy, and kidney-preserving surgery that removes only the tumour. He reaches the kidney robotically from behind, without entering the abdominal cavity, a technique he introduced to South West London where it is now the regional standard of care. He accepts referrals for tumours that other centres have declined for kidney-preserving surgery.
His robotic practice also includes pyeloplasty, ureteric reimplantation, adrenalectomy, nephroureterectomy and reconstruction, alongside the full range of treatments for an enlarged prostate, including Rezum, Aquablation, GreenLight laser and TURP.

His results
These figures come from Mr Sri's audited robotic series. Ask about any of them at your consultation.
Trifecta in robotic partial nephrectomy
Cancer fully removed with clear margins, no major complications, and the kidney's blood supply paused for under 25 minutes.
Conversion to open surgery
Across his robotic prostatectomy, partial nephrectomy and reconstructive practice to date.
Typical hospital stay
Median length of stay after robotic surgery. Most patients go home the following morning.
Highly complex kidney tumours
Of tumours treated with kidney preservation, 48% were in the highest complexity group (RENAL score above 10).
Continence after nerve sparing prostatectomy
Of men dry or with minimal leakage after nerve-sparing robotic prostatectomy.
Positive margin rate
In robotic partial nephrectomy, meaning cancer cells were found at the edge of the removed tissue in fewer than 1 in 100 cases.

Why patients are referred to Mr Sri
Patients and clinicians from across South West London and the UK come to Mr Sri for these reasons.
Robotic partial nephrectomyKidney cancer surgery
- Retroperitoneal expertiseOne of a small group of European surgeons using the approach from the back as standard.
- Complex tumoursAccepts tumours declined for kidney-preserving surgery elsewhere. 48% of his cases are in the highest complexity group.
- Second opinionsFor patients advised to have the whole kidney removed, or to stay on surveillance, who want to explore keeping their kidney.
- Previous abdominal surgeryApproaching from behind avoids the abdominal cavity and any scarring from past operations.
- A single kidneyWhen every bit of kidney function matters, preserving it is the priority, however demanding the surgery.
- Higher body weightThe approach from the back offers a more direct route to the kidney.
Robotic radical prostatectomyProstate cancer surgery
- High-volume robotic surgeon225+ robotic operations a year, with over 90% continence at one year after nerve-sparing surgery.
- Technique chosen for youPerforms both Retzius-sparing and standard nerve-sparing prostatectomy, selected for your cancer and anatomy.
- High-risk diseasePrincipal Investigator for the ELIPSE trial, with experience in T3 and high-risk cancer, including extended lymph node removal.
- Regional cancer leadUrology Cancer Lead at St George's, the tertiary centre for the South West London network.
- A trainer of surgeonsLeads the RCS-accredited robotic fellowship at St George's, recognised by the Royal College of Surgeons.
- Before radiotherapyAn expert surgical opinion if you are weighing up radiotherapy, or the choice is finely balanced.
Patients and referring clinicians are welcome. No GP referral is needed for a private consultation, and same-week appointments are available in Wimbledon, Kingston and Central London.
Helping to answer the big questions
Mr Sri is Principal Investigator at St George's for national clinical trials that shape how kidney and prostate cancer will be treated in future. Taking part is always voluntary, and he can tell you whether a trial might be right for you.
ELIPSE
Does removing the lymph nodes during surgery help men with high-risk prostate cancer?
A randomised trial comparing robotic prostatectomy alone with robotic prostatectomy plus removal of the pelvic lymph nodes.
PARTIAL
Is keeping part of the kidney as good as removing all of it for higher-risk tumours?
A randomised trial comparing robotic partial nephrectomy with removal of the whole kidney for patients with high-risk kidney tumours.
PART
Can treating only the cancer, rather than the whole prostate, work as well with fewer side effects?
A national randomised trial of focal therapy, which targets just the area of cancer within the prostate, compared with standard radical treatment for men with localised prostate cancer. What is focal therapy?
VISP
Do 3D models of a patient's own kidney help surgeons plan better?
A trial of 3D patient-specific models for planning robotic partial nephrectomy, compared with standard scans. It closed early after meeting its recruitment target ahead of schedule.

Training the next generation of robotic surgeons
Mr Sri leads the RCS-accredited robotic surgical fellowship at St George's, one of very few UK programmes accredited by the Royal College of Surgeons. Fellows train in robotic partial nephrectomy, radical prostatectomy, upper tract and pelvic reconstruction, adrenalectomy and female urology.
He mentors consultant colleagues from the UK and abroad, and teaches on national and international courses, including the FRCS Urology examination course.
