Abstract

Abstract:

Objective

To evaluate the clinical efficacy and safety of 6.0/7.5 F ureteroscopy combined with 200 μm holmium laser in the treatment of ureteral calculi.

Methods

90 patients with ureteral calculi admitted to our department were enrolled in this study. They were randomly divided into 6.0/7.5 F ureteroscope (URS) group and 8.0/9.8 F ureteroscope group, 45 patients underwent 6.0/7.5 FURS with 200 μm holmium laser; 45 patients underwent 8.0/9.8 F URS with 500 μm holmium laser. The data were compared.

Results

The success rate of operation in 6.0/7.5 F URS group was 100%, which was higher than that of 8.0/9.8 F group (P<0.05), and the ureteroscope dwelling time, intraoperative ureteral injury, operation time, postoperative complications, postoperative pain visual simulation score, and postoperative hospital stay were than better the 8.0/9.8 F group (P<0.05), there was no significant difference in the general conditions, ureteral injury and total hospitalization cost between the two groups (P>0.05). There were no serious complications such as ureteral avulsion and septic shock after operation in both groups.

Conclusions

6.0/7.5 F ureteroscope combined with 200 μm holmium laser for the treatment of middle and lower ureteral calculi was safe and efficent.
