Abstract

This report describes various techniques for fluoroscopy-guided removal of metallic ureteral stents. Fifteen patients underwent 17 fluoroscopy-guided removal procedures of 22 metallic ureteral stents. The simple or modified snare or retrieval hook technique was primarily used for antegrade access, whereas the loop snare technique was primarily used for retrograde access. Overall, 64.7% of the stents were removed using the initial retrieval technique, and 82.4% of the stents were removed using an adjunct technique. Procedure-related complications included hematuria in 41.2% of cases and resolved spontaneously in all patients. Fluoroscopy-guided removal of metallic ureteral stents is safe and effective.

摘要

本报告介绍了透视引导下取出金属输尿管支架的各种技术。15 名患者接受了 17 次透视引导下取出 22 个金属输尿管支架的手术。主要采用简单或改良的圈套器或取钩器技术进行顺行进入，而采用套圈器技术主要用于逆行进入。总体而言，64.7%的支架采用初始取出技术取出，82.4%的支架采用辅助技术取出。与操作相关的并发症包括血尿，占 41.2%，所有患者均自行缓解。透视引导下取出金属输尿管支架是安全有效的。
