BACKGROUND: The continuous intake of antithrombotic drugs during holmium laser enucleation of the prostate (HoLEP) remains nonconsensual. We aim to pool those controversial evidence and provide practical guidance of oral antithrombotics on HoLEP for benign prostate hyperplasia (BPH). METHOD: PubMed, Embase and CENTRAL database were systematically searched up to June 2019 for trials on patients with and without oral antithrombotics undergoing HoLEP. Number of events and mean value with standard deviation were, respectively, extracted for dichotomous and continuous parameters. Subgroup analyses of anticoagulation and antiplatelet were also performed. All statistical analyses were conducted with Review Manager v.5.3 software. Newcastle-Ottawa Scale (NOS) was used to assess the quality of selected trials. RESULT: Nine studies with 5528 patients were eventually selected, and patients included were generally older than 65 years. It revealed that the non-antithrombotic group had a lower rate of blood transfusion (OR 0.21, 95% CI 0.10-0.45, P < 0.0001), bladder tamponade (OR 0.30, 95% CI 0.13-0.69, P = 0.004) and acute urine retention (OR 0.52, 95% CI 0.30-0.89, P = 0.02). Operation time was also shorter (MD - 10.31, 95% CI - 12.76 to - 7.85, P < 0.00001) in the non-antithrombotic group, but the heterogeneity was considerable (I(2) = 75%). Subgroup analyses were generally consistent with the primary analysis except the non-anticoagulation and anticoagulation group having similar operation time (MD 6.66, 95% CI - 7.15 to 20.48, P = 0.34). CONCLUSION: The current study confirmed that continuous intake of antithrombotic drugs could significantly increase the risk of bleeding and blood transfusion, bladder tamponade and acute urine retention.
