Comparative Study On A New Pneumatic Probe And N-Trap Intercept Stone Network In The Treatment Of Upper Ureteral Calculi

Objective To compare clinical efficacy and safety of a new pneumatic probe and N-trap intercept stone network in the treatment of upper ureteral calculi,investigating the clinical application value of the new pneumatic probe.Methods 121 patients with upper ureteral calculi treated in this hospital were selected and randomly divided into two groups. Observation group: 59 cases were treated by ureteroscope lithotripsy with new pneumatic probe. Control group: 62 cases were treated by ureteroscope lithotripsy with N-trap intercept stone network.Results The immediate stone free rates was 91.53% in observation group and 95.16% in control group, the difference was not statistically significant(?2=0.647,P=0.484),the stone free rate after 1 month observation group was 96.61% and control group was 98.38%, the difference was not statistically significant( ?2=0.395,P=0.530). The difference of operating time between observation group and control group was not significant(t=1.627,P=0.106). There was no statistically significant in hospitalization(t=0.124,P=0.902), perioperative morbidity( ?2=0.180,P=0.672) between two groups. The clinical cost of the observation group was(11841±2642)yuan,the cost of the control group was(17384±1624)yuan, the difference was statistically significant(t=13.979,P=0.000).Conclusion The new pneumatic probe was safe and reliable, which can reduce the medical cost, more convenient in operation, deserving the clinical application.
