目的 探讨输尿管软镜下钬激光碎石术治疗肾下盏结石的治疗效果，并比较电子输尿管软镜与组 合式输尿管软镜下钬激光碎石治疗肾下盏结石的疗效。方法 回顾性总结肾下盏结石93 例患者，其中48 例采 用电子输尿管镜下碎石治疗（电子输尿管软镜组、DFU 组），45 例采用组合式输尿管镜下碎石治疗（组合式 输尿管软镜组、MFU 组），比较两组的碎石效果及并发症。结果 两组的平均碎石时间和一期结石清除率比较 差异均有统计学意义（P <0.05），住院时间、寻石成功率、并发症发生率和住院费用比较差异均无统计学意 义（P >0.05）。结论 DFU 和MFU 处理肾下盏结石均安全，有效。使用DFU 比使用MFU 治疗肾下盏结石 手术时间更短，结石清除率更高，效果更好。两者住院费用差异不大，但使用MFU 可适当减少科室成本。
Objective To evaluate the efficacy of flexible ureteroscopy combined with holmium laser lithotripsy for the treatment of subrenal calyx calculus, and comparing with digital flexible ureteroscope and modular flexible ureteroscope with holmium lithotripsy for the difference of the efficacy of the treatment of subrenal calyx calculus. Methods Review of the clinical data of 93 patients with subrenal calyx calculus, of which 48 cases were treated with digital flexible ureteroscope (digital flexible ureteroscope group, DFU group), 45 cases with modular flexible ureteroscope treatment (modular flexible ureteroscope group, MFU group), lithotripsy effect and complications were compared between the two groups. Results The mean operation time, one-session stone-free rate were significantly different between the two groups (P < 0.05). No significant differences in hospital stay, the success rate of looking for calculus, complication and hospitalization expense (P > 0.05). Conclusion With digital flexible ureteroscope and modular flexible ureteroscope treatment of subrenal calyx calculus all are safe and effective. The use of DFU than the use of MFU in the treatment of subrenal calyx calculus operation time is shorter, stone-free rate is higher, the effect is better. There is little difference between their hospitalization expenses, but the use of MFU can reduce the cost of the department.
