All patients underwent holmium laser procedure of ureteral lithotripsy from Aug 2016 to Aug 2018 in a primary hospital. Results Lithotripsy was performed successfully in all patients. Of 428，395 underwent one?stage lithotripsy with a success rate of 92.29% ；the stones were moved up to the kidney（6.31%）in 27 cases，and then extracorporeal shock wave lithotripsy（ESWL）was performed the double J tube was placed；3（0.7%）were changed to open surgery. No complications such as major bleeding ，ureteral tears ，severe infections occurred in all patients during and after operation.
