MP6-17 - Impact of antiplatelet and anticoagulation therapy for patients undergoing Thulium VapoEnuclation of the prostate (ThuVEP) on complication rates: a prospective study

Introduction & Objective : Aim of this study was to assess the complication rates in patients undergoing ThuVEP with and without ongoing antiplatelet or anticoagulation therapy.

Methods : A prospective study was performed on a consecutive series of patients who had received ThuVEP in a single institution from July 2016 to December 2017. Patients were divided into 4 groups: patients on ongoing aspirin monotherapy (n=34), patients with paused aspirin monotherapy (n=36), patients without antiplatelet/anticoagulation therapy (n=164), patients on anticoagulation therapy (bridged by low-molecular-weight heparin) (n=25).

Results : 259 patients underwent ThuVEP: 13.1% in the aspirin monotherapy group, 13.9% in the paused aspirin monotherapy group, 63.3% in the control group, and 9.7% in the anticoagulation group, respectively. Results are shown in Table 1. Patient groups were significantly different with regard to age and ASA group. Prostate volume tended to be lower in the anticoagulation group but did not pass the level of significance. During surgery, no differences were observed with regard to operative time and resected tissue. Postoperatively, the catheterization time was significantly different between the groups but not the postoperative stay. Postoperatively, blood transfusions were necessary in 1 patient (2.8%) with stopped aspirin therapy and in 2 patients (8%) on anticoagulant therapy. The 30-day total complication rate, classified according to the Clavien classification system was 5.9% in patients on aspirin monotherapy and significantly lower compared to patients on anticoagulant therapy (44%, p≤0.0004), and patients with paused aspirin monotherapy (25%, p≤0.0031), and did not differ from patients without antiplatelet/anticoagulation therapy (8.5%, p=0.4263).

Conclusions : Aspirin monotherapy did not impact the perioperative ThuVEP outcomes and should be continued during surgery. Stop of aspirin monotherapy might elevate the risk of complications in ThuVEP. Patients under oral anticoagulation bridged by low-molecular-weight heparin have a significantly elevated risk for complications compared to patients on antiplatelet treatment and controls.
