Mr Denosshan Sri

Mr. Denosshan Sri graduated from the University of Cambridge with a double first 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 as a Consultant Urologist at St George’s Hospital in 2021 — one of London’s largest trauma and tertiary referral centres.

Mr. Sri’s practice focuses on robotic kidney and prostate cancer surgery, and he currently leads the delivery of kidney cancer surgery and major trauma within the South West London Referral Network.

His subspecialty expertise lies in the management of kidney and prostate cancers, with a strong emphasis on robotic and minimally invasive surgical techniques. He is among a select group of surgeons in Europe specialising in robotic retroperitoneal partial nephrectomy, a pioneering procedure he introduced to South West London. This technique, now established as the standard of care for kidney cancer in the region, offers significant benefits to patients, including shorter hospital stays — often just one day — and faster recoveries.

Mr. Sri’s robotic practice also encompasses nerve-sparing radical prostatectomy for prostate cancer and complex reconstructive procedures for upper tract and pelvic pathology. He remains committed to nephron-sparing surgery even in challenging kidney cancer cases, prioritising the preservation of renal function while maintaining excellent oncological outcomes.

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 disorders and offers modern, minimally invasive, day-case surgical options such as GreenLight laser prostatectomy and Rezum therapy. He also provides robotic solutions for benign conditions, including female incontinence, ureteric obstruction and strictures, and reconstructive pelvic and upper tract pathologies.

Mr. Sri maintains a broad NHS practice, contributing to both benign and cancer multidisciplinary team (MDT) meetings. He also performs surgery for common inguinal, functional, and peno-scrotal conditions, including vasectomy, and offers comprehensive diagnostic evaluation for a wide range of urological concerns such as haematuria, elevated PSA, urinary tract infections, incontinence, lower urinary tract symptoms, and suspected malignancy.

As a high-volume robotic surgeon, Mr. Sri performs over 175 robot-assisted upper tract and pelvic procedures annually. Over the course of his career, he has accumulated extensive robotic experience, including more than 1500 robotic upper tract and pelvic procedures during his training at St George’s Hospital, fellowship at Frimley Park Hospital and subsequent consultant practice.

He leads the St George’s Robotic Fellowship Programme, training the next generation of surgeons and mentoring consultant colleagues in robotic techniques. He also plays a key role in expanding the application of robotic surgery into female and functional urology, including procedures for urinary incontinence, through close collaboration with subspecialty colleagues.

Alongside his clinical work, Mr. Sri is actively involved in research and surgical education. He has published extensively in peer-reviewed journals on prostate, kidney, and bladder cancer, as well as robotic reconstruction, and has contributed to book chapters. He serves as a principal investigator in clinical trials and regularly teaches and lectures at national and international courses and conferences.
