封堵取石导管治疗输尿管中上段结石的临床研究

Clinical research of block calculus extraction catheter under ureteroscopy in treating ureteral stones

摘要:

目的 探讨输尿管镜下配合应用英诺伟TMIVX-SC10/07新型封堵取石导管治疗输尿管中上段结石的临床疗效。方法 回顾性分析82例行输尿管镜钬激光碎石治疗输尿管中上段结石患者，随机分为两组，A组应用封堵器（40例）和B组应用鳄嘴取石钳（42例），比较两组患者的结石清除率及疗效。结果 A和B组两组的手术时间分别为（36±2）和（40±2）min，一次性结石清除率95.0％和66.7％，结石的近端距离肾盂分别为（5.0±1.5）和（6.0±1.2）cm，两组术后的平均出血量为（8±2）和（9±2）mL，术后发热分别为6和5例。结论 英诺伟TMIVX-SC10/07新型封堵取石导管在输尿管镜腔内碎石的过程中可以减少手术的时间，降低结石漂移至肾盂比率，提高碎石的功效，并且使用安全，有望成为输尿管镜碎石过程中重要的辅助器械之一。

Abstract:

【Objective】 To evaluate the clinical efficacy of INNOVEX TMIVX-SC10/07 block calculus extraction catheter in the ureteroscopic treatment of ureteral calculi. 【Methods】 A retrospective analysis of 82 cases of ureteroscopic holmium laser lithotripsy (URL) treatment in patients with upper ureteral stones was conducted, the patients were randomly divided into two groups: occluder was used in group A (40 cases) and group B in which crocodile stone forceps group (42 cases) were used. The stone clearance rate and curative effect were compared in the two groups. 【Results】 In A group and B group, operation time of two groups were (36±2) min and (40±2) min, respectively; disposable stone clearance rate was 95% and 66.7%, proximal renal pelvis stones from the distance were (5±2) cm and (6.0±1.2) cm, the average amount of bleeding after operation in two groups were (8±2) mL and (9±2) mL, postoperative fever in 6 cases and 5 cases, respectively. 【Conclusion】 Yingnuowei TMIVX-SC10/07, a new plugging stonecatheter can reduce the operation time, reduce the drift ratio increased to pelvis stones, stone effect, and much safer during ureteroscopic lithotripsy, is expected to become one of the important auxiliary appliance of ureteroscopic lithotripsy process.
