Extraction basket in ureteroscope holmium laser lithotripsy for upper ureteral calculi

Abstract

Objectives To investigate the clinical application value of ureteroscope holmium laser lithotripsy with NGage extraction basket in the treatment of upper ureteral calculi. Methods Totally 80 patients with upper ureteral calculi were randomly divided into two groups, 40 patients in control group were treated by ureteroscope holmium laser lithotripsy, 40 patients in observation group were treated by ureteroscope holmium laser lithotripsy combined with NGage extraction basket. Results The success rate of primary lithotripsy in observation group were 95%, which was higher than that in control group(75%), and the difference was statistically significant(P<0.05). The rate of residual calculi in observation group were 5%, which was lower than that in control group(20%), and the difference was statistically significant(P<0.05). There was no significant difference between two groups in the operation time, complication rate and hospitalization time. Conclusions NGage extraction basket with ureteroscope holmium laser lithotripsy could efficaciously prevent calculi from moving upward in the treatment of upper ureteral calculi, which could achieve higher success rate and lower residual calculi rate.
