Impact of antiplatelet therapy on risk of hemorrhage after percutaneous nephrostomy / 中国介入影像与治疗学

ABSTRACT

Objective To explore the impact of antiplatelet agents on the occurrence of hemorrhage after percutaneous nephrostomy (PCN).Methods Totally 197 patients (244 kidneys) underwent PCN were enrolled and divided into postoperative hemorrhage group and without postoperative hemorrhage group.The possible factors of the postoperative hemorrhage were analyzed.Results Post-operative hemorrhage occurred in 23 patients with 27 kidneys (27/244,11.07％).Univariate analysis showed that except for antiplatelet drugs,the other factors had no statistical difference between the two groups (P＞0.05).Logistic regression analysis showed that taking dual-antiplatelet was the risk factor of hemorrhage after PCN (OR=12.381,P =0.002).Conclusion Single aspirin therapy can not increase the risk of hemorrhage after PCN,while taking dual-antiplatelet might increase the risk of hemorrhage.Normal clotting function is also a guarantee of preventing hemorrhage after PCN.
