Transperineal Versus Transrectal Cognitive Fusion Prostate Biopsy

This prospective randomized controlled trial aims to compare transperineal and transrectal cognitive fusion prostate biopsy techniques in patients with suspicious prostate lesions detected by multiparametric magnetic resonance imaging (mpMRI). Patients aged 50-75 years with PI-RADS 3-5 lesions on mpMRI and an indication for prostate biopsy will be randomly assigned in a 1:1 ratio to undergo either transperineal cognitive fusion prostate biopsy or transrectal cognitive fusion prostate biopsy. The primary objective of this study is to evaluate whether transperineal cognitive fusion biopsy is non-inferior to transrectal cognitive fusion biopsy in detecting clinically significant prostate cancer (csPCa). Secondary objectives include comparison of overall prostate cancer detection rates, detection of Gleason Grade Group ≥2 prostate cancer, biopsy-related infectious complications, other procedure-related complications, pain scores, and procedure duration. A total of 280 participants will be enrolled. Pathological evaluation will be performed after biopsy, and clinical outcomes and complications will be assessed during follow-up.
