Abstract
BACKGROUND
According to the current definition of the German guideline for prevention of venous thromboembolism, urological surgery includes a high number of high-risk patients. All patients undergoing urological surgery between 2012 and 2016 were analyzed with regard to complications (bleeding or thrombosis).
MATERIALS AND METHODS
This study is a retrospective and monocentric cohort study. Included were all patients who underwent surgery between 2012 and 2016 at the Urological Department at the University Hospital of Luebeck. Information was collected relating to anticoagulation, patient-specific and surgery-specific risk factors, and complications.
RESULTS
In all, 3609 surgeries were analyzed: 77.8% of patients received no medical prophylaxis, 10.2% received an aggregation inhibitor, and 8.5% synthetic, unfractionated or low molecular weight heparin. Heparin was administered to 80.4% of patients after surgery. During an average hospital stay of 4.5 days, 93.3% of the patients received no change in anticoagulation. Merely 0.8% of all patients suffered from clinical thomboembolic events within 28 days. In contrast the number of bleedings was higher with 20.3% (minor: 4.8%, major: 15.5%).
CONCLUSION
We found a slight risk for postoperative thromboembolism (0.8%). The risk for postoperative bleeding in contrast was 20.3%, including 15.5% major bleedings. The results are discussed in relation to the current guidelines.
