Abstract：Objective:To investigate the clinical efficacy of ureteroscopic holmium laser lithotripsy combined with occluder & forceps for the treatment of intact ureteral calculi.Methods:The clinical data of 82 cases of uni-lateral intact ureteral calculi (30 cases of lower ureteral stones,23 cases of middle ureteral stones,and 29 cases of upper ureteral stones)treated by ureteroscopic holium laser lithotripsy combined with occluder & forceps from June 2013 to March 2016 in our hospital were retrospectively analyzed.The operation time,stone clearance rate, and postoperative complications were analyzed.Results:It worthed (5.0-14.5)min in lower ureter,(5.5-32.5) min in middle ureter,and (7.5-43.0)min in upper segment of the operation in research.Three days after surgery,KUB examination revealed 1 case of stone residual to the renal pelvis in the lower uretera with the net rate being 96.67%.There was 1 case of stone residual in the middle uretheral stones with the net rate being 95.65%.Another 1 case displaced to the renal pelvis and 1 case remained in the upper ureterald,which the net rate was 93.10%.No ureteral perforation or ureteral mucosa avulsion occurred in these operations.Figh fever oc-curred in 5 cases and cured by anti infection.The gross hematuria in 7 cases was improved after treatment with bladder irrigation after the operation.Conclusions:The application of ureteroscopic holium laser lithotripsy com-bined with occluder & forceps for intact ureteral calculi can significantly increase the stone-free rate,reduce uret-eroscopic lithotripsy stone drift,and shorten the hospitalization time.It will become a kind of important means of treatment of intact ureteral calculi with more safely and more efficiently.
