Effectiveness and safety of extended-duration prophylaxis for venous thromboembolism in major urologic oncology surgery.

Purpose: To examine the association between extended-duration prophylaxis (EDP), low-molecular-weight heparin prophylaxis for 28 days after surgery for urologic cancer in patients at high risk of developing a venous thromboembolism (VTE), the risk of VTE, and the complications resulting from VTE prophylaxis.

Materials And Methods: The cohort included 332 patients at high risk for VTE who were surgically treated for urologic cancer from June 2011 to June 2014. Adherence to VTE prophylaxis protocol, VTEs, and complications within 365 days from surgery were tracked.
