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 →
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.

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.
