目的:探讨输尿管结石封堵器在输尿管镜钬激光碎石术处理输尿管上段结石中的应用价值和疗效。方法:术中置入封堵器后,在输尿管结石上端形成球状阻隔,可防止结石上移,提高碎石成功率。结果:除1例结石上移以外,其余29例均一次性碎石成功。术后复查碎石效果好,肾盂内无残留结石,患侧肾积水消退。结论:应用输尿管结石封堵器治疗输尿管上段结石疗效确切,值得临床应用和推广。
Objective: To investigate the value and efficacy of ureteral calculi occluder in ureteral calculi treated by ureteroscopic holmium laser lithotripsy. Methods: After intraoperative occluder, ureteral stones formed on the top of the spherical barrier to prevent stones move up, improve the success rate of gravel. Results: Except for one case of stone metastasis, the remaining 29 cases were all successful in one time. Postoperative review of lithotripsy, renal pelvis no residual stones, ipsilateral hydronephrosis subsided. Conclusion: The application of ureteral calculi occluder in the treatment of upper ureteral calculi is effective and worthy of clinical application and promotion.
