Continued administration of antithrombotic agents during transperineal prostate biopsy.
OBJECTIVE
To determine the safety of continued administration of antithrombotic agents during transperineal (TP) prostate biopsy.


METHODS
A total of 811 men who underwent transrectal ultrasound (TRUS)-guided TP biopsy from January 2008 to June 2012 at our two institutions were retrospectively analyzed. Among these 811 men, 672 received no antithrombotic agents (group I), 103 received and continued administration of antithrombotic agents (group II), and 36 interrupted administration of antithrombotic agents (group III). Overall complications were graded and hemorrhagic complications were compared (group I with group II) using propensity score matching (PSM) analysis.


RESULTS
An overall complication rate of 4.6% was recorded. Hemorrhagic complications occurred in 1.8% and they were virtually identical in all the three groups, and no severe hemorrhagic complications occurred. One patient in group III required intensive care unit admission for cerebral infarction. PSM analysis revealed no statistical difference between groups I and II with regard to the incidence of gross hematuria, perineal hematoma, and rectal bleeding. Multiple regression analysis revealed that hemorrhagic complications were associated with lower body mass index (<21 kg/m2, P=0.0058), but not with administration of antithrombotic agents.


CONCLUSIONS
Continued administration of antithrombotic agents does not increase the risk of hemorrhagic complications; these agents are well tolerated during TP biopsy.
