Prévention de la maladie thromboembolique en chirurgie urologique

Few scientific evidences are available in the literature, and the methodologic quality of the studies is often under average. Nevertheless, the conclusions are the following. Nephrectomy, renal transplantation, open surgery of the lower urinary tract and lumbar or pelvic lymph nodes dissection are at high risk for thromboembolic events. Other open or endoscopic urological procedures are at low risk. The laparoscopic approach doesn't change the risk associated with the procedure itself. Thromboprophylaxis is recommended in high-risk procedures. There was no evidence to recommend starting the prophylaxis before more than after the procedure. The use of low molecular weight heparin is recommended for prophylaxis. It can be associated with compressive stockings. It is recommended to treat for around seven days after the procedure. In case of cancer surgery, prophylaxis could be needed for four to six weeks.
