目的：探讨NTRAP阻石篮在输尿管镜钬激光碎石术中的价值和安全性。方法：采集2010年1月-2014年4月中50例输尿管上段结石患者，按随机数字表法为为阻石篮组19例和对照组31例。阻石篮组以输尿管镜在斑马导丝引导下进入输尿管见到结石后，于输尿管镜工作通道内放置NTRAP阻石篮，以钬激光完全粉碎结石至直径小于2 mm碎片后松开阻石篮，拔除阻石篮后留置双J管。术后第1天复查KUB，双J管于术后1~3个月拔除。对照组不使用NTRAP阻石篮，单纯使用钬激光碎石。比较两组的治疗效果。结果：NTRAP阻石篮组一次性碎石成功率达89.4%，高于对照组的74.2%，两组比较差异有统计学意义（P<0.05）。NTRAP阻石篮组的住院天数、手术时间均明显优于对照组（P<0.05）。NTRAP阻石篮组无结石移位，对照组6例出现结石移位。两组术后均无严重并发症。结论：NTRAP阻石篮操作简单、方便，一次性碎石成功率较高，可对输尿管结石产生有效封堵，预防输尿管结石碎石术中结石移位。

Objective:To evaluate the efficacy and safety of NTRAP Retrieval Basket in ureteroscopic Holium laser lithotripsy for upper ureteral stone.Method:From January 2010 to April 2014,50 cases of upper ureteral stone were selected,and they were randomly divided into the NTRAP group(n=19)and the control group(n=31). The NTRAP group was treated with ureteroscope insert through the ureter to find stones aided by zebra guide wire,and then NTRAP retrieval basket was placed in the working channel of ureteroscope.When stones were crushed into fragments of 1-2 mm in diameter by lumenis holmium laser,the device was removed. The Double-J tube was placed.X ray was conducted and Double-J tube was retained in all the patients for 1-3 months postoperatively.The lumenis holmium laser without NTRAP retrieval basket was used in the control group.Result:One-time gravel success rate of the NTRAP group was 89.4%, and was higher than the 74.2%in the control group,there was significant difference(P<0.05). The hospitalization days and operation time in the NTRAP group were better than the control group(P<0.05). The NTRAP group was no stone shift,the control group had 6 cases. There were no serious postoperative complications of two groups .Conclusion:The application of NTRAP retrieval basket in ureteroscopic holium laser lithotripsy for upper ureteral stone is a highly effective and safe therapy and one-time gravel success rate is more higher. It can prevent stones from drifting during lithotripsy.
