Bleeding Events Associated With Continuing Antithrombotic Therapy During Transrectal Ultrasound-Guided Prostate Biopsy: A Propensity Score-Matched Analysis.

Kenichi Hata et al. · International journal of urology : official journal of the Japanese Urological Association · 2026
Purpose

To evaluate the association between antithrombotic continuation and the frequency and severity of bleeding events during transrectal ultrasound-guided prostate biopsies.

Methods

This retrospective cohort study involved 1248 patients who underwent transrectal ultrasound-guided prostate biopsy between April 2018 and December 2024.

n = 1248 patients
Results

diabetes is linked to higher odds of serious bleeding after prostate biopsy

OR 3.47 (95% CI 1.10 to 10.96)
null 1
1.10
10.96
CI excludes the null - significant
More results

Propensity score matching yielded 162 patients per group.

Hematospermia rates did not differ significantly.

In the unmatched direct-acting oral anticoagulant cohort, severe rectal bleeding occurred in three patients (5.7%).

“
Conclusion · 1 of 2

Transrectal ultrasound-guided prostate biopsy was generally safe without antithrombotic discontinuation, with no significant increase in bleeding events.

Conclusion · 2 of 2

Caution is warranted when continuing direct-acting oral anticoagulants, particularly in patients with risk factors for bleeding, such as diabetes mellitus.
