Abstract

Abstract:

Objective

To compare the efficacy between Sun's ureteroscope and flexible ureteroscope for renal calculus(≤2 cm).

Methods

The data of 123 patients with kidney stones(≤2 cm) treated in our hospital from January 2014 to March 2017 were analyzed. Sixty patients were treated Sun's ureteroscopic lithotripsy (observation group), while the other sixty-three patients were treated with flexible ureteroscopic lithotripsy (control group). The success-rate of endoscopic insertion, endoscopic insertion time, the success rate of lithotripsy, stone-free rate, postoperative complication rate, postoperative hospital stay, hospitalization expenses in two groups were evaluated.

Results

The differences of the rate of endoscopic insertion, the success rate of lithotripsy, stone-free rate and postoperative hospital stay between the two groups weren't statistically significant (P>0.05). There were significant differences in endoscopic insertion time, postoperative complication rate, hospitalization expenses between the two groups (P<0.05).

Conclusions

The Sun's ureteroscope is safe and effective in the treatment of renal calculi. It has its unique advantages and deserves further aplication in clinical practice.

Key words: Ureteroscope, Renal calculus, Holmium laser
