Impacto de la biopsia transrectal de próstata en la función eréctil

Abstract

Background

The procedure of transrectal biopsy of the prostate (TRBP) is not exempt from complications. Between 1-6.9% of men that undergo TRBP present with adverse effects such as hematuria, hematospermia, dysuria, or fever, and 0.5%-5% will present with septicemia.

Aim

To evaluate erectile function in Mexican men that underwent TRBP.

Material and methods

A total of 324 patients underwent TRBP. All the patients were evaluated through the International Index of Erectile Function (IIEF-5) questionnaire. All patients that had a positive result for cancer and that presented with erectile dysfunction at the initial evaluation were excluded from the study. Ninety-three patients were included and were evaluated with the IIEF-5 before the biopsy and at 4, 12, and 24 weeks after TRBP.

Results

At the baseline IIEF-5 evaluation, 100% of the 93 patients were potent. At post-TRBP week 4, the mean IIEF-5 score was 22 points (range: 11-25). Significant difference was found when the groups were evaluated (P = .001), given that > 30% presented with some grade of erectile dysfunction, compared with the baseline evaluation. At week 24, only 7.25% of the patients presented with some grade of erectile dysfunction.

Conclusions

After TRBP, the decrease in the IIEF-5 scores and the presence of erectile dysfunction was temporary and transitory, having a greater effect during the first month after the procedure. There was improvement after the first month and an almost complete recovery at 6 months.
