目的探讨腔镜下钬激光碎石与气压弹道碎石治疗输尿管上段结石的疗效和安全性。方法比较两种碎石方法的一次碎石成功率、手术时间、术后4周结石排净率、严重并发症发生率等指标的差异性。结果两组间一次碎石成功率、手术时间和术后4周结石排净率的差异有统计学意义(P<0.05),两组均无严重并发症发生。结论与气压弹道碎石相比,钬激光更适合应用于输尿管上段结石的腔镜治疗。
Objective To investigate the efficacy and safety of endoscopic holmium laser lithotripsy and pneumatic lithotripsy in the treatment of upper ureteral calculi. Methods The two gravel methods were compared, including the success rate of primary gravel, the operation time, the rate of stone clearance 4 weeks after operation, and the incidence of serious complications. Results There was a significant difference between the two groups in the success rate of primary lithotripsy, the operation time and the stone clearance rate after 4 weeks (P <0.05). No serious complications occurred in both groups. Conclusion Compared with pneumatic lithotripsy, holmium laser is more suitable for endoscopic treatment of upper ureteral calculi.
