Abstract

OBJECTIVES:

To assess the impact of transrectal versus transperineal prostate biopsy on erectile function.

METHODS:

This was a single-center, observational, prospective study of consecutive patients who underwent a prostate biopsy (transrectal or transperineal/fusion biopsy). Study participants completed the International Index of Erectile Function-5 questionnaire before the procedure, and 3 and 6 months after. Prostatic biopsies were carried out following the standard procedure for both techniques.

RESULTS:

The study included 135 male patients with a mean age of 63.5 years. At baseline, 28 patients (21%) presented normal erectile function, whereas 107 patients (82%) presented erectile dysfunction, which was severe in four (3%), moderate in 49 (36%) and mild in 54 (40%), with an overall mean International Index of Erectile Function-5 score of 17.70. After 3 months, the rates were 29%, 3%, 27% and 38%, respectively (mean International Index of Erectile Function-5 score 17.95). At 6 months, the rates were 30%, 6%, 28% and 34%, respectively (mean International Index of Erectile Function-5 score of 17.77). No significant differences between pre- and post-biopsy International Index of Erectile Function-5 scores at 3 and 6 months were observed, even when analyzing transrectal and transperineal separately. The number of biopsy cores and number of previous biopsies did not influence the International Index of Erectile Function-5 scores.

CONCLUSIONS:

Our findings suggest that prostate biopsy technique, number of biopsy cores and history of previous biopsy do not significantly impact erectile function in the medium term up to 6 months.
