Recently Mr Johnston and Mr Brewin have been part of the team joining the PREMISE trial. The PREMISE (Prostate Resection versus Minimally Invasive Surgery Evaluation) trial is a National Institute for Health Research study to investigate the comparative effectiveness of four different prostate surgeries - TURP, iTIND, Rezum and Urolift. Mr Johnston is principal investigator in Salisbury. If you are interested in discussing any of these surgeries please arrange an appointment.
