Ureteral stents represent a minimally invasive alternative to preserve urinary drainage whenever ureteral patency is deteriorated or is under a significant risk to be occluded due to extrinsic or intrinsic etiologies. The ideal stent that would combine perfect long-term efficacy with no stent-related morbidity is still lacking and stent usage is associated with several adverse effects that limit its value as a tool for long-term urinary drainage. Several new ideas on stent design, composition material and stent coating currently under evaluation, foreseen to eliminate the aforementioned drawbacks of ureteral stent usage. In this article we review the currently applied novel ideas and new designs of ureteral stents. Moreover, we evaluate potential future prospects of ureteral stent development adopted mostly by the pioneering cardiovascular stent industry, focusing, however, on the differences between ureteral and endothelial tissue.
输尿管支架是一种微创替代方法，可在输尿管通畅性恶化或由于外在或内在病因而有明显阻塞风险时保留尿液引流。理想的支架应具有完美的长期疗效，且无支架相关并发症，但目前仍缺乏这种支架，并且支架使用会引起多种不良反应，限制了其作为长期尿液引流工具的价值。目前正在评估一些关于支架设计、组成材料和支架涂层的新想法，以期消除输尿管支架使用的上述缺点。本文综述了目前应用的新型输尿管支架的想法和设计。此外，我们还评估了输尿管支架发展的潜在未来前景，主要借鉴了开创性的心血管支架行业的经验，但重点关注输尿管和内皮组织之间的差异。
