Abstract: 【Abstract】〓Objective〓To investigate clinical effect and safety of holmium: YAG laser lithotripsy under ureteroscopy for managing upper ureteral calculi. Methods〓The clinical data of 112 cases of ureter calculi treated by ureteroscope with Holmium laser lithotripsy were retrospectively analyzed. Among these patients, 63 were male, and 49 were female. The age of the patients varied between 18~87 years with a mean age of 46.7 years. The largest diameter of the largest stone was 0.7~2.2 cm (1.2±0.5 cm). There are 5 cases of bilateral upper ureteral calculi, and the total number of left upper ureteral calculi was 61, and the right side was 46. There were 26 cases affiliated with ureteral polypus, and 31 cases with ESWL treatment history preoperative. All the cases had different degrees of hydronephrosis. Results〓The overall successful operation rate for all level of ureteral stones in single procedure was 88.4% (99/112). The operation time ranged 15~80 min (33.6±16.8 min), and the postoperative hospital stay was 3~14 d (4.7±2.1 d). No complications occurred such as severe hematouria, ureteral perforation, ureteral avulsion and ureteral stone street in this post cohort operation. There were three cases with urinary tract infection and suffered fever. Urosepsis occurred in one case, and cured by timely anti-infection treatment. Conclusion〓Rigid ureterorenoscopy using Ho:YAG laser lithotripsy for upper ureteral calculi can be an effective and safely performed technique.
