目的 :探讨双J管内引流在上尿路手术中的应用效果。方法 :术中经肾盂或输尿管切口置入双J管 ,并保证其远端进入膀胱内 ,必要时可采用带尾线双J管。双J管放置时间以 4～ 6周为宜。结果 :184例患者均达良好引流目的 ,无一例发生吻合口漏尿及狭窄、闭塞等。结论 :采用双J管内引流具有操作简便 ,引流支架效果好 ,并发症少等优点 ,宜推广使用 Objective: To investigate the effect of double J tube drainage in upper urinary tract surgery. Methods: Intraoperative renal pelvis or ureter incision into the double J tube, and ensure its distal into the bladder, if necessary, can be used with a tail line double J tube. Double J tube placement time to 4 to 6 weeks is appropriate. Results: All 184 patients achieved the goal of good drainage without any anastomotic leakage, stenosis and occlusion. Conclusion: The double-J tube drainage has the advantages of simple operation, good drainage stent effect, fewer complications, should be widely used
