目的:探讨双输尿管导管在微创经皮肾镜钬激光碎石术中的应用。方法:对2009年6月～2012年5月采用双输尿管导管逆行插管法行超声引导下经皮肾镜取石术治疗的多发性肾结石28例临床资料进行回顾性分析。结果:28例均一次穿刺造瘘成功,碎石取石时间为25～120min,术中无结石颗粒进入输尿管腔,术中很容易确认UPJ位置,放置斑马导丝及顺行留置双J管均顺利。结论:双输尿管导管逆行插管法在经皮肾镜取石术中有助于阻挡结石颗粒下移入输尿管,有助于确定UPJ位置及放置斑马导丝及双J管,可节约手术时间;术后有助于小结石颗粒的排出,值得推广应用。
Objective: To explore the application of double ureteral catheter in minimally invasive percutaneous nephrolithotomy with holmium laser lithotripsy. Methods: The clinical data of 28 cases of multiple nephrolithiasis treated with ultrasound-guided percutaneous nephrolithotomy were retrospectively analyzed from June 2009 to May 2012 with double ureteral catheter retrograde intubation. Results: All the 28 cases were successful in puncture. The time of lithotripsy was 25 ~ 120min. There were no stones in the ureter during operation. The UPJ position was easily identified during operation. . Conclusion: The double ureteral catheter retrograde intubation method can help to prevent stones from moving into the ureter during percutaneous nephrolithotomy. It is helpful to determine the position of UPJ and place the zebra guide wire and double J tube to save the operation time. After operation Contribute to the discharge of small stones, it is worth promoting.
