We present the contemporary risk of venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), after renal surgery. METHODS We enrolled patients undergoing partial and radical nephrectomy to a prospective observational study with the primary outcome measure of VTE events. The study was approved by our IRB, and baseline demographic data was collected at time of consent. The timing and type of perioperative prophylaxis (including pharmacologic prophylaxis, sequential compression devices (SCD) and thromboembolic deterrent stockings (TED)) was left to the discretion of the operating surgeons. In order to capture all events including post-hospital-discharge events, participants were contacted by phone at least 6 weeks postoperatively and interviewed about undergoing evaluation for or being diagnosed with a clinically significant VTE. Retrospective chart review was performed for patients who were not reachable. RESULTS Between April 2011 and October 2012, 94 patients were enrolled: 22 (23.4%) open radical nephrectomy, 31 (33.0%) laparoscopic radical nephrectomy, 20 (21.3%) open partial nephrectomy, and 21 (22.3%) robotic partial nephrectomy. Patient data in regard to mechanical and pharmacologic VTE prophylactic measures and VTE rates across all procedures are shown in the Table. Three patients (3.2%) were diagnosed with a VTE; all 3 received postoperative pharmacologic prophylaxis prior to the VTE (mean 16 hours postoperatively). On multivariate analysis the rate of VTE was not significantly affected by patient age, sex (all three were female, no statistically significant difference), length of surgery, partial vs. radical nephrectomy, open vs. minimally invasive approach, and benign vs. malignant pathology. CONCLUSIONS In a prospective, non-randomized study, we observed a low overall risk (3.2%) of VTE after partial and radical nephrectomy. In this cohort, with limited statistical power to rule out a possible benefit, the use of pharmacologic VTE prophylaxis did not significantly modify VTE risk. Patient enrollment is ongoing to further enhance the power of this study.
