【摘要】 目的:评价B超引导下经皮肾镜Cyberward双导管碎石术和气压弹道联合超声碎石术对于鹿角形肾结石的疗效。方法:前瞻性地将138例鹿角形肾结石患者随机分成双导管组(A组,n=71)和弹道联合超声组(B组,n=67)。比较两组间术前资料、手术时间、出血量、住院时间、住院费用、并发症。结果:两组均成功建立通道并且行一期碎石,术前两组间结石大小、年龄构成、合并症等均未见差别。术中碎石时间A组明显短于B组[(77.14±21.39)vs(84.25±20.62)mL,P=0.049],术中出血量以及术后诸指标差异无统计学意义。两组一期结石清除率分别为67.6%和70.1%,差别无统计学意义(P=0.854)。结论:两种碎石方法对于鹿角形肾结石均安全有效。双导管碎石术更加高效,操作更简单。更多还原

【Abstract】 Objective: To evaluate and compare the eiciency and safety of Cyberwand dual probe lithotriptor and Swiss lithoclast master in percutaneous nephrolithotomy for renal staghorn calculi.Methods: A total of 138 patients with renal staghorn calculi were divided randomly into a Cyberwand dual probe lithotripter group(Group A,n=71) and a Swiss lithoclast master group(Group B,n=67).he data for operative time,blood loss volume,one-stage calculus clearance rate,hospitalization time,cost of hospitalization and complication in the two groups were collected and compared.Results: The renal access was established successfully and the one-stage percutaneous nephrolithotomy(PCNL) was performed in the 2 groups.There was no significant difference in the size of stones,the age of patients and the complications between the 2 groups before the operations.Intraoperative gravel time in the Group A was signiicantly shorter than that in the Group B(77.14±21.39 vs 84.25±20.62,P=0.049).There was no significant difference in the one-staged stone clearance rate,blood loss volume in the operation between the 2 groups.he one-staged stone clearance rate in the 2 groups were 67.6%(48/71) and 70.1%(47/67) respectively,with no signiicant diference(P=0.854).Conclusion: Two lithotrities were safe and eicient for renal staghorn calculi.But comparing with Swiss lithoclast master,Cyberwand dual probe lithotriptor is more eicient and convenient.更多还原
