Stone retropulsion during ureteroscopic lithotripsy may lead to additional procedures needed for residual calculi. Several devices have been introduced in an attempt to reduce retropulsion. We set out to report our initial experience utilizing the new polymeric gel, BackStop.
We prospectively collected data on 7 ureteroscopy procedures with distal ureteral calculi treated with BackStop. Perioperative data including stone size, location, operative time, stone free rate, the presence or absence of retropulsion was collected. Success was defined as no residual fragments, no retropulsion, and no additional procedures required.
All of the patients were rendered stone free after URS and no retropulsion occurred. There were no intraoperative complications nor gel migration or problems with dissolving the gel.
BackStop is a new promising therapy to prevent retropulsion during ureteral intracorporeal lithotripsy. It is safe, easy to apply and very effective in preventing stone fragment migration. BackStop has the potential to reduce operative time.
输尿管镜碎石术中结石后推可能导致残留结石需要额外的手术。已经引入了几种设备来试图减少后推。我们着手报告我们使用新型聚合物凝胶BackStop的初步经验。
我们前瞻性收集了7例使用BackStop治疗远端输尿管结石的输尿管镜手术数据。收集围手术期数据，包括结石大小、位置、手术时间、结石清除率、是否存在后推。成功定义为无残留碎片、无后推且无需额外手术。
所有患者在输尿管镜检查后结石均被清除，且未发生后推。术中无并发症，凝胶无迁移或溶解问题。
BackStop是一种预防输尿管体内碎石术中后推的新的有前景的治疗方法。它安全、易于应用且在预防结石碎片迁移方面非常有效。BackStop有减少手术时间的潜力。
