- robotic prostatectomy
Mr Mayer has both a private and an NHS practice at The Royal Marsden. He is a Clinical Senior Lecturer at Imperial College London, and an Honorary Consultant Surgeon at Imperial College Hospital NHS Trust and The Royal Marsden. His sub-specialist interests are in testicular, prostate and kidney cancer.
He is one of two surgeons in the South East England Supranetwork Testicular Multidisciplinary Team and performs retroperitoneal lymph node dissection for testis germ cell tumours. At The Royal Marsden, minimally invasive approaches to this surgery using both conventional keyhole surgery and robotic surgery are being developed to improve the outcomes, including shortening the hospital stay and recovery time.
He is also a robotic prostate surgeon and was part of the team that developed the first UK programme for robotic prostatectomy in 2004. He regularly performs robotic prostatectomy at The Royal Marsden and is developing a new pathway of care for patients who are eligible for salvage prostatectomy surgery for recurrent disease after other treatments.
Mr Mayer has completed a PhD thesis evaluating aspects of the Quality of Care in Surgery with emphasis on improved techniques for appraising surgical performance and outcomes. Continued research in this area is undertaken in the Centre for Health Policy (Institute for Global Health Innovation) and includes evaluating metrics that encompass the entire patient pathway and novel assessment tools for capturing the quality of the patient experience during treatment episodes. Health technology assessment research is focused on enhancing the quality and safety of minimally invasive surgery (including robotics) using image-guided technology.
