Anticoagulant and antiplatelet medications are commonly used for the treatment and prevention of cardiovascular diseases. We studied 84 patients who received heparin as a bridging anticoagulant and antiplatelet therapy during the perioperative period. Hospitalization was extended for adjusting anticoagulant and antiplatelet drugs and also bleeding complications in the perioperative period. There were 25 instances of bleeding complications (29.7%) in this study. These complications mainly occurred when anticoagulant and antiplatelet medications were restarted in the postoperative period. In transurethral surgery, patients taking warfarin and antiplatelet drugs (aspirin or ticlopidine) had a statistically significant increase in bleeding complications compared to patients taking warfarin alone. We compared 51 cases of transurethral resection of bladder tumor, transurethral resection of the prostate holium laser enucleation of the prostate, nephroureterectomy and percutaneous nephrolithotomy with heparinization were compared to 692 cases with no heparinization. The heparinization group had a statistically significant longer hospitalization period and an increase in bleeding complications. There was one instance of thromboembolism (1.2%) in our series. This involved stent thrombosis of a patient who had drug-eluting stent in the left anterior descending coronary artery. She died three days postoperatively. The number of patients taking anticoagulant and/or antiplatelet drugs is predicted to increase in the future due to aging of the population. Guidelines for the management of anticoagulant and antiplatelet therapy in the urological period are considered necessary.

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...
