A Prospective Study Of Free-Hand Transperineal Image Fusion Targeted Biopsies Under Local Anesthesia

12-core transrectal ultrasound (TRUS) biopsy is one of the most performed urological procedures and remains the standard method for prostate cancer (PCa) histological diagnosis according to the most recent Guidelines. During the last decade, the transperineal prostate biopsy has attracted renewed interest. However, only a few studies and no large prospective studies investigated complications of the transperineal approaches. Image fusion of Multi-parameter MRI (mpMRI) and TRUS guided prostate targeted biopsy had equivalent results with standard 12-core biopsy. Combination of targeted and standard biopsy was recommended in recent Guidelines. Image fusion targeted biopsy needs satisfactory anesthetic effect, and no prospective studies investigated feasibility in this approach under local anesthesia. The scientific urological community is focusing on detection rate and concordance with final pathology of the radical prostatectomy specimen, which remain the cornerstones to assess the accuracy of a prostate biopsy technique. In this study, the investigators will additionally assess the functional results of erectile function and urinary function. Together, the investigators will perform free-hand image fusion targeted biopsies plus standard biopsies under local anesthesia in patients recruited in this study. Then, Feasibility, such as peri-procedural pain, changes in patients quality of life; complications, such as infection rate and bleeding rate; functional results, such as erectile function and urinary function; and concordance with final pathology will be evaluated.
