折叠式结石拦截器在经皮肾镜取石术中的应用

目的 探讨折叠式结石拦截器在经皮肾镜取石术(PCNL)治疗肾结石中的有效性和安全性.方法 回顾分析108例行PCNL肾结石患者临床资料.术中应用折叠式结石拦截器56例,未应用52例.2组患者性别、年龄、结石大小比较差异均无统计学意义(P＞0.05).比较2组在结石清除率、手术时间、术中出血量、住院天数和并发症等差异. 结果 2组结石清除率分别为94.6%(53/56)和82.7%(43/52),手术时间分别为112、142 min,出血量为205、245 ml,差异均有统计学意义(P＜0.05).2组住院时间分别为2.8、3.0 d,并发症发生率分别为16.1%(9/56)和15.4%(8/52),2组比较差异无统计学意义(P＞0.05). 结论折叠式结石拦截器使用简单、方便、安全,PCNL术中能有效阻止结石碎片下滑进入输尿管,提高结石清除率、缩短手术时间、减少手术出血量、不增加手术并发症.

Abstract：

Objective To evaluate the efficacy and safety of percutaneous nephrolitholomy with a PercSys accordion stone management device in the treatment of renal calculi. Methods The data of 108 patients with renal calculi who underwent PCNL were retrospectively analyzed. Outcomes of 56 patients who underwent PCNL with the PercSys accordion device (group A) were compared with the outcomes of 52 patients who underwent PCNL without the accordion device (group B). Clinical data including stone-free rate, operative time, estimated blood loss, length of hospital stay and complications were compared. Results The stone-free rates of group A and group B were 94. 6% and 82.7%, operative time was 112 min and 142 min, the mean blood loss was 205 ml and 245 ml, respectively. The differences between the 2 groups were significant(P＜0. 05). The length of hospital stay was 2.8 d and 3.0 d, the complication rates were 16.1 % and 15.4%. There was no significant difference between the 2 groups for these 2 aspects(P＞0. 05). Conclusions The PercSys accordion device can be easily inserted and deployed during PCNL. It successfully prevents antegrade stone fragment migration, increases the stone-free rate and reduces the operative time and blood loss.
