封堵装置在输尿管结石腔内碎石中的应用

摘要

Migration of ureteral stones or stone fragments is quite common during the ureteroscopic lithotripsy for proximal ureteral stones. Such complications require additional procedures, which increases the cost and time of treatment. Occlusion devices can prevent the migration and improve stone-free rate. This article is a summary of our experience on several commonly used occlusion devices.%输尿管结石及结石碎片向肾盂迁移是输尿管上段结石在输尿管镜腔内碎石中的常见问题,往往需要进一步处理,增加了治疗成本和时间,而结石封堵装置的应用则明显降低了此种情况的发生率,提高了结石清除率.本文综述了目前常用的封堵装置的临床应用情况.
