An Observational Study on the Effect of Sextant TRUS-Guided Biopsy on Erectile Function

Objective: Many complications after prostate biopsy (PB) have been reported. One of the possible complication after PB is erectile dysfunction (ED). In this study, we showed the early (1 month after PB) effect of PB on erectile function. Materials and Methods: A total of 207 men who underwent PB between April 2021 and October 2021 were evaluated. Before and 1 month after PB, all patients were evaluated with the IIEF-5 (5-item version of the International Index of Erectile Function) prospectively. Patient data such as age, body mass index, prostate-specific antigen levels, prostate volume, periprostatic local anesthesia, pathological results, and post-biopsy complications were noted. Results: The mean IIEF-5 score was 13.3 (5-25) before PB. One month after the biopsy it was 13.5 (5-25). There were no differences between the before and after PB IIEF scores. The only significant change was observed in the prostate cancer (PCa) group. Conclusion: In past studies, it has been shown that ED after prostate biopsy is mostly seen at the first month and improves after that. In our study, PB did not affect erectile function. Only the PCa-diagnosed group showed a significant decrease in erectile function, and this effect was not attributed to prostate biopsy.
