Methods For 35 child patients with middle and lower ureteral calculi, the dilation of orifice was taken by 6.0 ～ 8.0 F fascia dilator, then ureteroscopic holmium laser lithotripsy followed. Results Among the 35 cases, 33 cases were the successful gravel, with a total rate of 94.3％ gravel. In other two cases, the broken stones were rushed into the renal pelvis and ESWL was successfully carried.
