Methods: One hundred and thirty-five cases of ureteral calculi treated by ureteroscope, cystoscope or percutaneous nephrolithotomy were included. Fifteen cases of kidney stones and 17 cases of bladder stones were treated. Results: Of the 167 patients, 152 cases of first-stage operation gravel were successful, and the postoperative recovery was satisfactory. No serious complications occurred. Conclusion: Holmium laser is an effective and safe treatment for urinary calculi with less trauma, less bleeding, less complications and faster recovery. It is worthy of clinical promotion.
