摘要本文报道3例经皮肾造瘘术及肾造瘘管置换术中损伤下腔静脉的患者，1例为经皮肾造瘘术中损伤腔静脉，经CT检查明确后，在CT下直接拔除造瘘管；其他2例为肾造瘘管置换术中损伤下腔静脉，经CT检查明确后，逐步拔除肾造瘘管。3例术后均顺利撤除误入下腔静脉的肾造瘘管，无继发下腔静脉或肾静脉损伤，无继发血栓形成，均顺利行再次肾造瘘术。

abstractsThis study reported three patients with inferior vena cava (IVC) injury during percutaneous nephrostomy or nephrostomy catheters exchange. After CT examination, the tube of one case with IVC injury during percutaneous nephrostomy was directly extracted under the supervision of CT. The tube of the other 2 cases with IVC injury during nephrostomy catheters exchange were gradually removed after CT examination. The three patients’ nephrostomy tubes were removed successfully after surgery, without secondary vena cava, renal vein injury, and secondary thrombosis, and then they were all safely reperformed with percutaneous nephrostomy.
