Objective To investigate feasibility, efficacy and safety of holmium laser lithotripsy under ureteroscopy to treat ureteral calculi. Methods Clinical data of 162 patients with ureteral calculi treated by holmium laser lithotripsy under ureteroscopy in our hospital from June 2006 to October 2009 were reviewed retrospectively. Stone-broken rate,lithagogue rate and complication were observed. Results The overall rate of successful fragmentation for all levels of ureteral calculi in a single procedure achieved 96. 30% (156/162). The success rates of fragmentation for the upper and mid-lower segment of ureteral calculi was 86.11% (31/36)and 99.21% (125/126),respectively. In 156 patients, the postoperative follow-up of 2- 4 weeks revealed that the stone free rate was 98.08 % (153/156). The mean operative time was (36 ± 11 )mains ( ranged from 15 to 90) and hospital stay ranged from 1 to 10 days. Conclusion Holmium laser lithotripsy under ureteroscopy is feasible,high effective and safe for the treatment of ureteral calculi, especially for those with middle or lower levels ureteral calculi.
