Can prostate biopsies affect erectile function?

Area of Science:

• Urology
• Andrology
• Medical Imaging

Background:

• Erectile dysfunction (ED) is a common concern, particularly in men undergoing prostate cancer screening.
• Transrectal ultrasound (TRUS)-guided prostate biopsy is a standard diagnostic procedure.
• The potential impact of TRUS biopsies on erectile function requires careful evaluation.

Purpose of the Study:

• To prospectively assess the effect of TRUS-guided prostate biopsies on erectile function.
• To determine the incidence of biopsy-attributed erectile dysfunction.
• To correlate pre-existing ED with post-biopsy outcomes.

Main Methods:

• Prospective study of 46 men undergoing TRUS-guided prostate biopsies.
• Assessment of erectile function using the International Index of Erectile Function (IIEF)-5 questionnaire at baseline, 1 month, and 3 months post-biopsy.
• Recording of concomitant ED-related diseases and medications.

Main Results:

• Median IIEF-5 scores showed no statistically significant decline post-biopsy (15.91 pre-biopsy vs. 14.33 at 1 month vs. 14.81 at 3 months; P > 0.05).
• Pre-existing ED was prevalent (82.60%), with mild to severe classifications.
• Biopsy-attributed ED occurred in a small percentage of patients (6.52% at 1 month, 4.34% at 3 months).

Conclusions:

• TRUS-guided prostate biopsies do not appear to induce erectile dysfunction in a statistically significant manner.
• The majority of ED observed post-biopsy is attributable to pre-existing conditions or medications.
• Pre-procedure evaluation of erectile function is recommended for baseline assessment.
