X-ForceN30肾造瘘球囊扩张导管在经皮肾镜碎石术通道建立中的运用

摘要

目的 探讨X-ForceN30肾造瘘球囊扩张导管在经皮肾镜碎石术(PCNL)通道建立中的可行性及安全性.方法将2011年9月至2012年3月该科行PCNL 47例病例随机分为两组,对照组(29例)采用传统钢制套叠扩张鞘建立经皮肾镜通道,实验组(18例)采用X-ForceN30肾造瘘球囊扩张导管建立经皮肾镜通道.以穿刺成功植入经皮肾镜后图像显示结石并且超声显示穿刺入目标肾盏为止,记录两组穿刺时间、穿刺出血量、一次性成功率、穿刺并发症.结果 47例手术均获成功.对照组穿刺时间(13.4±2.7)min,穿刺出血量(15.4±9.7)mL,一次穿刺成功27例(93%),2例二次穿刺成功,1例出现刺破肾盏,并发症发生率3.44%;实验组穿刺时间(7.4±1.2)min,穿刺出血量(8.3±2.3)mL,所有病例均一次穿刺成功,无通道丢失,一次性成功率100%,无穿刺并发症.所有数据采用t检验进行统计分析,实验数据比较差异有统计学意义(P<0.05).结论 X-ForceN30肾造瘘球囊扩张导管作为一种新型的穿刺器械,在PCNL通道建立中具有穿刺快、穿刺准确、出血少的优点,值得推广.%Objective To investigate the the feasibility and safety of the X-ForceN30 nephrostomy balloon dilatation catheters in establishing the channel of percutaneous renal lithotripsy. Methods 47 cases of PCNL from Sep,2011 to Mar,2012 were randomly divided into a control group of 29 cases using traditional steel overlay expansion sheath establishment of percutaneous nephrolithot-omy channel and an experimental group of 18 patients with X-the-ForceN30 nephrostomy balloon catheter based percutaneous neph-rolithotomy channel. Until the nephrolithotomy image showed the stone after the success of puncture implantation in the percutaneous nephrolithotomy, and the ultrasound showed puncture reached the target calyceal,the puncture time,bleeding quantity,one-time success rate and puncture complications of each group were recorded. Results 47 cases were all successful. In the control group,the puncture time were (13.4±2.7) min,the bleeding quantity were (15.4±9.7) mL,27 cases were one-time success puncture, 2 cases conducted successful second puncture,and there was 1 case of punctured calyceal. The one-time success rate and complication rate were 93% and 3. 44% respectively in the control group. In the experimental group, the puncture time were (7.4±l.2) min,the bleeding quantity were (8.3±2.3) mL,and all cases were one-time success puncture, which means the one-time success rate was 100%. In addition, there were no channel lost, and there were no puncture complications, either. All data were analyzed by t-test,and the differences were statistically significant. Conclusion X-ForceN30 nephrostomy balloon catheter is a new type of puncture equipment with advantages of fast,accurate and less bleeding,and it is worthy of being promoted.
