Objectives To investigate the efficacy of using ureteroscopic holmium laser lithotripsy to treat patients with ureteral stones.Methods We retrospectively analyzed the clinical materials of 498 cases patients in our hospital using ureteroscopic holmium laser lithotripsy to treat patients with ureteral stones from May 2006 to December 2011,255 cases for upper ureteral stones and others for middle-lower ureteral stones.Results The overall successful rate of fragmentation for all ureteral stones in a single procedure achieved 88.6％ (441/498),and respectively for the upper,middle-lower ureteral stones were 83.1％ (212/255) and 94.2％ (229/243),with a significant difference compared between the two groups (P ＞ 0.05).There were 316 cases (348 sides) with ESWL history,and the successful rate of fragmentation in a single procedure was 88.0％ (278/316).182 cases (213 sides) without ESWL history got the successful rate of fragmentation in a single procedure at 91.8％ (167/182),without any significant difference compared with each other(P ＞ 0.05).Operation time ranged 15 ～ 130 min (mean 41.4 ± 25.6 min),and (mean 22.39 ± 6.15) min for the group of middle-lower ureteral stones,(37.52 ± 8.41) min for the other group,with a significant difference compared.The duration of hospitalization after operation was2 ～ 15d,with an average(4.7 ± 2.6)d.32 sides was abandoned,which migrated to the renal pelvis.The patients were reviewed by KUB plain 3 weeks after lithotripsy.The stone-free rate was 97.9％ (238/243) in the middle-lower ureteral stones group,which was significantly higher than that in the upper ureteral stones group 91.0％ (232/255,P ＜ 0.05).necessary.There were 68 sides with urinary tract infection and suffered fever with the highest temperature at 40.3℃ and no one with ureteral avulsion or longterm complications such as ureteral stricture.Conclusions The transureteroscopic holmium laser lithotripsy is both mnimally invasive and effective therapy for patients with ureteral calculi,especially for the middle-lower ureteral stones
