Mr Denosshan Sri
MA Cantab · MB BChir · FRCS Urol

Mr Sri is a consultant urological surgeon at St George's University Hospital, where he is Kidney Cancer Lead for the South West London referral network and leads the RCS-accredited robotic surgical fellowship. He graduated from the University of Cambridge with a double first and performs over 200 robotic urological procedures per year.

His Central London practice at HCA Princess Grace focuses on his two subspecialty areas: kidney cancer surgery — particularly retroperitoneal robotic partial nephrectomy, a kidney-preserving approach he introduced to South West London — and prostate cancer surgery including nerve-sparing robotic radical prostatectomy. He accepts tertiary referrals for complex kidney tumours from across the UK and welcomes second opinions.

He is Principal Investigator in two clinical trials: PARTIAL (robotic partial vs radical nephrectomy for high-risk kidney tumours) and ELLIPSE (RARP vs RARP with lymph node dissection for high-risk prostate cancer). Full profile and publications →

Kidney cancer · Subspecialty approach

Retroperitoneal robotic partial nephrectomy

Most surgeons perform kidney cancer surgery through the abdomen. Mr Sri approaches the kidney from behind — through the retroperitoneal space — without entering the abdominal cavity at all. This eliminates bowel handling, resulting in faster gut recovery, less post-operative bloating, and a smoother path home. For posterior and upper pole tumours it also provides the most direct operative route.

He is one of a small group of surgeons in Europe to use this approach as their default, and has published its long-term outcomes in the Journal of Robotic Surgery. He accepts referrals for tumours declined elsewhere for kidney-preserving surgery — 48% of his cases are in the highest complexity category.

Prostate cancer · Subspecialty approach

Nerve-sparing robotic prostatectomy

Robotic-assisted radical prostatectomy for prostate cancer demands precision in preserving the neurovascular bundles responsible for erectile function — a task uniquely suited to the magnification and wristed instrument control of the robotic platform. Mr Sri's prostatectomy programme includes mandatory pre-operative pelvic floor physiotherapy and structured post-operative survivorship.

He is PI of the ELLIPSE trial evaluating lymph node dissection in high-risk prostate cancer, accepts patients with complex staging, and provides second opinions on treatment choice between surgery and radiotherapy.

"Mr Sri has made my experiences very easy to deal with and I have felt that everything moved swiftly and professionally, with scans and procedures booked quickly and easy to understand follow ups."
Patient · Verified Doctify review
"I saw Mr Sri for prostate surgery and felt confident in his care from the outset. He explained everything clearly, took time to answer my questions, and made sure I understood the options and likely outcomes. His calm and straightforward manner was very reassuring throughout. The surgery and follow-up were well managed, and I felt genuinely supported at every stage. I'm very grateful for his care and would highly recommend him."
