[Significance of drug prevention of thromboembolism in urologic risk patients].

The phlebothrombosis and pulmonary embolism are severe postoperative complications. Urological patients are particularly at risk with thrombosis. Therefore it becomes necessary for urology to perform a consequent prophylaxis of thromboembolism which, when an increased risk is present, must contain medicamentous measures. As it is confirmed by evident studies, the low-dose heparin prophylaxis proved as optimum method. A still more effective thrombosis protection can be achieved by the combination of small heparin doses with dihydroergotamine. Retrospectively, 2 comparable groups of urological risk patients with and without heparin prophylaxis were examined. In the adenomectomies under heparin prophylaxis a trend to the reduction of the events of postoperative thromboembolism is revealed. The heparin prophylaxis does not lead to an increase of complications of haemorrhages which need therapy. The prophylaxis of thromboembolism with heparin and a heparin-DHE-combination, respectively, is recommended for the application in urological risk patients.
