Professional background

Consultant urological surgeon (robotic prostate cancer consultant).

Mr Prasanna Sooriakumaran (PS) is a consultant urological surgeon specialising in robotic surgery for prostate cancer. He is a visiting senior clinical researcher at Oxford University, honorary associate professor at University College London, and has been visiting professor at St Antonius Hospital in Germany and Mount Sinai School of Medicine in New York.

PS moved to UCLH in 2017 from Oxford University having worked at The Churchill as a high volume prostate cancer surgeon. He trained as a fellow for two years at Cornell University in New York and the Karolinska Institute in Stockholm, before his direct appointment to Oxford by the Nuffield Department of Surgical Sciences. PS is known internationally for his pioneering work in robotic surgery, especially with regards graded nerve sparing and Retzius sparing, fields in which he has published extensively. PS is a National Clinical Excellence Award holder, a Health Services Journal Cancer Judge, and sits on the research panel of The Urology Foundation. He is also a committee member of the UK National Cancer Research Institute Advanced Prostate Clinical Studies Group due to his work in surgery for metastatic prostate cancer. This expertise has also facilitated his appointment to the trial management group of the STAMPEDE trial, the world’s largest interventional trial in advanced prostate cancer. PS is a former member of the European Association of Urology (EAU) young academic group in prostate cancer and the EUA robotic urology section scientific working party, and maintains his collaborations with urology leaders across the world.

Research interests

PS’ research work, funded by a Prostate Cancer Foundation Young Investigator Award and The Urology Foundation’s Research Scholar Medal, examines the role of surgery in treating men with advanced prostate cancer. This work embodies the world’s first clinical trial of surgery for men with oligo-metastatic prostate cancer (the TROMBONE trial), and a larger, follow-up trial is being planned. PS is also the Chief Investigator for the RESTART trial, a study examining the benefit of Retzius sparing robotic surgery to standard robotic surgery for men with prostate cancer; this trial is a multi-centre study funded by The Urology Foundation Research Innovation Award and the Intuitive Surgical Clinical Studies Award.

PS is also a Principal Investigator for studies testing the comparative effectiveness of surgery versus advanced radiotherapy techniques (PACE trial), patient outcomes for robotic surgery after focal therapy (RAFT trial), results of surgery versus focal therapy (PART trial), and the role of novel imaging with PSMA-PET in high-risk prostate cancer (PANORAMA trial).

PS is the Surgical lead for two of these multi-centre trials: PART and PANORAMA. The overarching goal of PS’ research is to improve outcomes for patients with prostate cancer.


PS has written 2 books, and published over 20 book chapters and 10 newspaper articles. His peer-reviewed indexed publications in medical journals have had over 5000 citations. His publications in 2021 are listed below, but the full list can be accessed at:
