The Impact of Multiple Prostate Needle Biopsies on Long-Term Erectile Dysfunction.

Introduction: The impact of transrectal ultrasound guided prostate needle biopsy on erectile dysfunction remains uncertain. We examined whether transrectal ultrasound guided prostate needle biopsy contributes to the development or worsening of erectile dysfunction as assessed by IIEF-5 scores in patients who underwent multiple prostate needle biopsies.

Methods: The study population consisted of 826 men who underwent transrectal ultrasound guided 10 to 12-core prostate needle biopsy for suspicion or surveillance of prostate cancer.
