Zeng H, Gao M, Chen J, et al. - This study was undertaken to investigate the incidence and risk factors of venous thromboembolism (VTE) in patients undergoing percutaneous nephrolithotomy (PCNL). In the analysis, the records of 896 consecutive cases receiving PCNL between July 2018 and August 2020 were retrospectively examined. The risk factors of VTE were distinguished by performing univariate analysis. The independent risk factors were ascertained by conducting multivariate logistic regression analysis. It has been reported that 2.8% of patients developed VTE following PCNL. Due attention should be paid to the effective thromboprophylaxis and the early detection of VTE regarding those patients who have independent risk factors in this study.
