Objectives To describe a step‐by‐step guide for using the first transperineal targeted prostate biopsy platform available in the USA. Patients and Methods A total of 32 men with elevated prostate‐specific antigen (PSA) levels were diagnosed with a region of interest on multiparametric magnetic resonance imaging (mpMRI) between February 2017 and January 2018. The transperineal targeted prostate biopsy procedure was accomplished via a transperineal approach and used a stepper, combined with advanced mpMRI/transrectal ultrasound fusion software, to perform targeted prostate biopsy. The detection of overall and clinically significant prostate cancer (PCa) was assessed as well as the rate of complications. Results The median patient age was 68.0 years and the median PSA was 8.0 ng/mL. Two patients (6%) were active surveillance candidates and 16 (50%) had a prior negative prostate biopsy. The detection rates for overall and clinically significant PCa were 81% and 59%, respectively. The two candidates for active surveillance and eight of the patients with a prior negative prostate biopsy had clinically significant PCa confirmed on targeted biopsy. There were no peri‐operative complications. Conclusion These results demonstrate the promising potential of the first transperineal targeted prostate biopsy platform in the USA as an alternative diagnostic method for PCa.
