Evaluation of Targeted Biopsy Plus Sextant Biopsy in Diagnosis of Prostate Cancer

The biopsy procedure was conducted by a highly skilled and experienced urologist who specializes in performing prostate biopsies. Prophylactic antibiotics were routinely used both before and one day prior to scheduled surgery. Each patient was placed in the left lateral position or lithotomy position. The ultrasound equipment used included a color Doppler ultrasound diagnostic instrument (Hitachi HiVision, Philips Epiq 7), transrectal probes, and corresponding puncture needle guns. Color Doppler examination was performed from the base to the apex. For each predefined mpMRI suspicious lesion, urologists firstly obtained three-core TB from the lesion within the mpMRI suspicious lesion. Then urologists obtained sextant six-core SB. Each core was placed in an individual container and reported separately in accordance with the Ginsburg scheme. Histology was evaluated by senior uropathologists who were blinded to the imaging findings.
