title: Can prostate biopsies affect erectile function?
abstract: The impact of transrectal ultrasound (TRUS)-guided prostate biopsies on erectile function was prospectively studied. Forty-six men (median age: 67.51 years) who underwent TRUS-guided prostate biopsies completed the International Index of Erectile Function (IIEF)-5 questionnaire at the day of the biopsy, 1 and 3 months later. Erectile dysfunction (ED) severity was classified into five categories. Concomitant ED-related systemic diseases and/or medications that could affect erectile function were also recorded. The paired t-test was used for statistical analysis. The median IIEF-5 score was 15.91 prior to biopsies, while 1 and 3 months after, the median IIEF-5 score was 14.33 and 14.81 respectively (P > 0.05). Prior to prostate biopsies, ED was reported by 38 patients (82.60%): mild ED in 39.13%, mild to moderate in 19.56%, moderate in 15.21% and severe ED in 8.69%. Concomitant ED-related systemic diseases and/or medications were recorded in 28 patients (60.86%). One month after, ED was revealed in 42 patients (91.30%): mild ED in 26.08%, mild to moderate in 30.43%, moderate in 19.56%, and severe ED in 15.21%. Three months post-biopsy, ED was reported by 41 patients (89.13): mild ED in 21.73%, mild to moderate in 28.26%, moderate in 21.73%, and severe ED in 17.39%. Overall, three and two patients (6.52% and 4.34%) had prostate biopsy attributed ED (i.e. without concomitant ED-related disease or medication) 1 and 3 months after prostate biopsies. TRUS-guided prostate biopsies did not induce ED in a statistically significant manner. Evaluating potency at referral for TRUS-guided prostate biopsies is advisable.
