Picture-in-picture video demonstration of systematic transperineal prostate biopsy

There is no gold standard protocol for total number of cores required in any patient; it is dictated by hospital policy, availability of resources, and the experience of the urologist. The instruments used during the procedure comprised an ultrasound machine with long side-fire sensor probe, a bed with two leg supports to facilitate lithotomy position, one disposable biopsy gun, two needles for local anaesthesia, two metal trocars, and eight specimen bottles. Ethics approval This study was approved by the Joint Chinese University of Hong Kong[-]New Territories East Cluster Clinical Research Ethics Committee (Ref CREC 2018.323).
