Analysis of holmium laser lithotripsy under ureteroscopy in the treatment of 160 patients with ureteral calculi

Objective To analyze the clinical efficacy and safety of holmium laser lithotripsy under ureteros-copy in the treatment of ureteral calculi .Methods The clinical data of 160 patients with ureteral calculi were retro-spectively analyzed .All patients received the epidural or general anesthesia surgery ,guide wire was inserted through ureteroscopy,holmium laser lithotripsy line,postoperative indwelling double J tube 2-4 weeks.Results Of 160 cases, a single stone crushing operation was 94.37%;mean operative time was 51min.All patients had mild hematuria,3 ~4d may disappear.By 1 to 3 months follow-up,stone clearance rate was 97.5%.The success rate of gravel for surgical ureteral calculi was 70.27%, and middle and lower ureteral stone gravel-time success rate was 99.20%.Conclusion Holmium laser lithotripsy under ureteroscope in the treatment of ureteral calculi is safe ,effective,and has minimally invasive,fewer complications.
