Evaluation of the short-term cessation and early initiation of antithrombotic therapy in high-risk patients undergoing HoLEP procedure for large prostates (> 100 mL): A critical evaluation
Background: To characterize the safety and efficacy of Holmium Laser Enucleation of Prostate (HoLEP) in patients with large prostates (>100ml) at high risk for thromboembolic events (TE) resuming antithrombotic treatment (AT) in the early postoperative period. Methods: Data for 378 men with large prostates treated with HoLEP for symptomatic benign prostatic hyperplasia between December 2016 and July 2020 were reviewed retrospectively. Of the patients, 134 had been receiving AT, (anticoagulant (AC), n=51; antiplatelet (AP), n=83). AT was resumed within 24 hours postoperatively. We determined pre-, peri-, and postoperative parameters, functional outcome, and adverse events for the 3-month period postoperatively in patients receiving AC and AP; and compared results with 203 patients without AT. Results: Patients receiving AC and AP were older (p=0.015) and had a higher median ASA score (p<0.001). Objective voiding parameters (Qmax, PVR) and urinary symptoms (IPSS, QoL) improved in the three groups (p<0.001). Median enucleation and morcellation efficiencies were 1.58 (IQR:0.87-3.13) and 5 (IQR:1-8.08), median catheterization and hospitalization time was 2 days (IQR:2-3) and 3 days (IQR:3-4), respectively. The perioperative results were similar in the three groups. Overall, one patient in the AP group required blood transfusion at 4 days postoperatively due to clot retention and significant hemoglobin decrease (p=0.216). There was no adverse TE in any patient within 3-month postoperatively. Conclusion: HoLEP is an effective and safe method in patients with a high risk of TE whose AT is discontinued for surgery, as it enables AT to be resumed as soon as possible.
