New oral anticoagulants (NOACs) are increasingly replacing the use of warfarin in clinical practice. Their use has now also been extended to thromboprophylaxis in many orthopedic surgeries. This, in addition to an increasingly aging population with many complex comorbidities means that these medications will be ever more frequently encountered by urologists. Thus, a clear understanding of the mechanism of action of NOACs, their time to peak action and half-life is essential for the purpose of managing these patients perioperatively. This article demonstrates the patient and procedural variability that must be taken into account in the perioperative management of the anticoagulated patient. While the time to peak onset and half-life of NOACs can aid in determining the interval of interruption of anticoagulation, the risks of thrombosis and bleeding must be assessed before the decision to stop anticoagulation. This article takes into account the evidence available on NOACs in urological surgery in order to inform the perioperative management of these medications and to propose guidelines to aid in clinical decision making. In attempting this, we address the issue of the lack of high-level evidence surrounding NOACs in urological surgery given their relative novelty and the need for further research to better guide practice.
新型口服抗凝药(NOACs)在临床实践中越来越多地取代了华法林的使用。它们目前也已扩展到许多骨科手术的血栓预防。此外,随着人口老龄化加剧以及许多复杂的合并症,泌尿科医生会越来越频繁地遇到这些药物。因此,为了围手术期管理这些患者,清楚了解NOACs的作用机制、达到峰值作用的时间和半衰期至关重要。本文展示了抗凝患者围手术期管理中必须考虑的患者和手术过程的变异性。虽然NOACs达到峰值起效时间和半衰期有助于确定抗凝中断的间隔时间,但在决定停止抗凝之前,必须评估血栓形成和出血的风险。本文考虑了泌尿外科手术中关于NOACs的现有证据,以便为这些药物的围手术期管理提供信息,并提出有助于临床决策的指南。在尝试这样做时,鉴于NOACs相对新颖且需要进一步研究以更好地指导实践,我们解决了泌尿外科手术中围绕NOACs缺乏高级别证据的问题。
