Objective To study the effect of intercepting basket or occluder and non-occlusion device in the operation of upper ureteral calculi.Methods A total of 90 patients underwent ureteral calculi from February 2015 to February 2017 were randomly divided into control group, occluder group and basket group. The control group did not use the blocking device, the occluder group using N-Trap intercept network, the basket group using the British Connaught occluder. Comparison of the three groups of stone clearance rate, the success rate of disposable gravel, stone uptake rate, the incidence of complications, operation time, postoperative hospital stay was performed.Results The success rate of the lithotripsy rate and the disposable gravel were significantly higher in the occluder group and the basket group than in the control group, the difference was statistically significant (P<0.05). The net basket rate and the success rate of the disposable gravel were higher than occluder group, the difference was not statistically significant (P>0.05). The incidence of complications and the incidence of complications were slightly lower than those of the control group (P<0.05). The incidence of complications and the rate of stone migration were lower than those of the control group. There was no significant difference between the two groups (P>0.05). The time of operation and the time of hospitalization were shorter than those of the control group, the difference was statistically significant (P<0.05). There was no significant difference between the operation time and the hospitalization time and the occluder group (P>0.05).Conclusions Interventional basket or occluder is effective in the treatment of upper ureteral calculi with ureteroscopic holmium laser lithotripsy, which can effectively improve the rate of stone and the success rate of disposable crushed stone, reduce the occurrence of calculus and complication, promote the early rehabilitation of patients, clinical patients can choose according to the actual situation of the device.
