Mr Denosshan Sri

Mr Denosshan Sri graduated from the University of Cambridge with double first-class honours and completed his subspecialty urological training in South West London. He subsequently undertook a highly competitive fellowship in robotic kidney cancer surgery at Frimley Park Hospital before being appointed Consultant Urologist at St George's University Hospitals NHS Foundation Trust (2021) & Kingston Hospital (2024) — St George's being one of London's largest trauma and tertiary referral centres.

Mr Sri's practice focuses on robotic kidney and prostate cancer surgery, specifically nerve sparing robotic assisted radical prostatectomy and robotic assisted partial nephrectomy. He is among a select group of surgeons in Europe specialising in robotic retroperitoneal partial nephrectomy — a nephron-sparing technique he introduced to South West London and which is now established as the standard of care for kidney cancer in the region. He performs this approach as his default technique for kidney cancer, including the most complex, high-RENAL score tumours. Patients typically spend just one night in hospital and return to normal activity within two to four weeks.

He holds six concurrent NHS leadership positions across St George's and the wider South West London urology network: Kidney Cancer Lead for the South West London Referral Network, Cancer Lead for Urology, Robotic Steering Group Lead, RCS and BAUS-accredited Robotic Fellowship Lead, Urological Trauma Lead at St George's, and Urology Robotic Lead at Kingston Hospital.

Mr Sri's robotic practice also encompasses nerve-sparing radical prostatectomy for prostate cancer, with excellent continence rates, and complex reconstructive procedures for upper tract and pelvic pathology. He remains committed to nephron-sparing surgery even in challenging kidney cancer cases, prioritising preservation of renal function alongside excellent oncological control. He accepts tertiary referrals for complex kidney and prostate cancer from across the UK.

In addition to his cancer practice, Mr Sri manages a broad range of general urological conditions in both men and women. He has a particular interest in benign prostate enlargement and offers modern, minimally invasive, ejaculatory-preserving day-case treatments including Rezum water vapour therapy, Aquablation, GreenLight laser prostatectomy, and TURP. He also provides robotic solutions for benign conditions including urinary incontinence, ureteric obstruction and strictures, and complex reconstructive pelvic and upper tract pathology.

As a high-volume robotic surgeon, Mr Sri performs over 200 robot-assisted procedures annually. His total robotic caseload across training, fellowship, and consultant practice now exceeds 1,500 upper tract and pelvic procedures — one of the largest personal series in the UK.

As Robotic Fellowship Lead at St George's, Mr Sri trains the next generation of robotic urological surgeons through the RCS and BAUS-accredited fellowship programme — the only such programme in South West London. He is Principal Investigator on two active randomised controlled trials: the ELLIPSE trial, examining robotic prostatectomy with and without pelvic lymph node dissection in high-risk prostate cancer, and the PARTIAL trial, comparing robotic partial versus radical nephrectomy for high-risk renal tumours. He has published extensively in peer-reviewed journals on prostate, kidney, and bladder cancer and robotic reconstruction, contributed to surgical textbook chapters, and teaches regularly at national and international conferences including the BAUS FRCS Urology Course.

Mr Sri offers a complete diagnostic and treatment pathway — from initial assessment through to robotic surgery, MDT review, and specialist follow-up — for kidney cancer, prostate cancer, haematuria, raised PSA, urinary tract infections, incontinence, lower urinary tract symptoms, and benign scrotal and inguinal conditions including vasectomy.
