Abstract：Self-expanding metallic ureteral stents(EMUS)provides a safe and effective minimally invasive op-tion for treating ureteral strictures,with notable clinical advantages,particularly in malignant obstruction and complex cases.Following EMUS placement,patients exhibit marked symptomatic relief and improved quality of life.Howev-er,stent-related complications such as migration,infection,and obstruction require careful consideration,with nota-ble variations in the applicability of different stent types.Future advancements aim to integrate intelligent stent sys-tems and personalized therapeutic regimens to enhance efficacy and reduce adverse events.This study synthesizes re-cent research on EMUS,including applications of mainstream devices(e.g.,MemokathTM,Allium®,UventaTM),to comprehensively analyze their indications,implantation techniques,therapeutic outcomes,and associated complica-tions,while comparing the efficacy of various stent designs.Additionally,long-term follow-up data and cost-effective-ness are evaluated based on the literature data.
