Abstract：Objective:To explore the clinical application of ureteral occlusion devive in prevention of moving up of middle of upper ureteral calculi ureteral. Method:From December 2011 to December 2012 62 cases of unilateral middle and upper ureteral calculi with ureteroscopic working channel was arranged in the Yingnuowei TMIVX-SC10 ureteral occlusion devive,completely beyond calculus after operation in vitro,handle to blade folding to prevent movement of calculus, and then using the holmium:YAG laser lithotripsy or ballistic lithotripsy,after the completion of the blade in the rubble stone fragments from ureter folded cavity. D-J tube indwelling ureter stenosis patients without stricture of ureter catheter 4 weeks,patients with stricture of ureter catheter for eight weeks.Result:5 cases of upper ureteral calculi ureteral stones in the placement of pipeline occluder when moved to the ipsilateral renal calyx with D-J indwelling tube,carried out the extracorporeal shock wave lithotripsy postoperative,the effect was satisfaction.Residual ureteral calculi patients were occluded satisfaction,there were no patients with ureteral perforation or ureteral mucosa avulsion.There were no postoperative patients with high fever,bacteremia,renal failure.After D-J tube removal of abdominal plain film,except for 5 cases of calculus into a calculus patients with extracorporeal lithotripsy kidney in the light of not emptying,more than 57 cases of no residual stones.Conclusion:Ureteral occlusion devive can significantly reduce the ureteral calculi ureteral calculi lithotripsy up,improve the stone clearance rate,reduce the two operation or follow-up treatment,the operation is simple,is worthy of clinical application.
