Abstract：Objective To analyze the efficacy of the"three-step method"versus traditional ureteroscopic holmium laser lithotripsy(UHLL)in the treatment of ureteral calculi.Methods A total of 204 patients with ureteral calculi admitted to the Department of Urology,South Campus of Fengxian District Central Hospital,Shanghai from July 2022 to January 2025 were prospectively selected and divided into a control group(108 cases)and a study group(96 cases)according to the surgical method.The control group was treated with traditional UHLL,while the study group was treated with the"three-step method"using an occlusion catheter,holmium laser,and stone extraction basket.Perioperative indicators,stone escape rate,stone clearance rate,complications,and recurrence were compared between the two groups.Results In the study group,operation time,intraoperative blood loss,urinary catheter removal time,double-J stent removal time,and hospital stay were significantly lower/shorter than those in the control group[(22.85±3.06)min vs(26.33±3.47)min,P<0.001;(24.62±3.22)mL vs(27.04±3.91)mL,P<0.001;(3.14±0.52)d vs(4.96±1.05)d,P<0.001;(18.11±2.87)d vs(24.83±3.22)d,P<0.001;(5.36±1.25)d vs(6.92±1.46)d,P<0.001].The stone escape rate in the study group was lower than that in the control group,while the stone clearance rates at 1,2,and 3 months after surgery were higher(P<0.05).The complication incidence and recurrence rate in the study group were 6.25%and 4.17%,respectively,lower than the 15.74%and 12.04%in the control group(P<0.05).Conclusion Compared with traditional UHLL,the"three-step method"of occlusion catheter,holmium laser,and stone extraction basket can shorten operation and recovery time,reduce stone escape,improve stone clearance rate,and lower the risk of postoperative complications and recurrence in patients with ureteral calculi.
