Ureteral stents are routinely used in urological practice for many indications including obstruction of ureter, ureteral stricture, prior to treatment with extracorporeal shock wave lithotripsy, and to promote healing following ureteral injury. Complications reported with ureteric stents include stent migration, stent rupture, encrustation, ureteral perforation, erosion, and fistulation. Knotting of an indwelling ureteral stent is a very rare complication, with fewer than 30 cases reported in the literature. Techniques for managing this complication include using a holmium laser to cut the knot, percutaneous antegrade removal, and gentle traction. We describe the case of a knotted stent and its removal along with a comprehensive literature review.
输尿管支架在泌尿外科实践中常规用于多种适应症，包括输尿管梗阻、输尿管狭窄、体外冲击波碎石治疗前，以及促进输尿管损伤后的愈合。输尿管支架相关的并发症包括支架移位、支架破裂、结石形成、输尿管穿孔、侵蚀和瘘管形成。留置输尿管支架打结是一种非常罕见的并发症，文献报道的病例少于30例。处理这种并发症的技术包括使用钬激光切割结、经皮顺行取出和轻柔牵引。我们描述了一例支架打结及其取出的病例，并进行了全面的文献综述。
