Ureteral stents are commonly used in urology but are frequently associated with patient discomfort, stent encrustation and stent-related infection. New biomaterials, coatings and designs have been designed to attempt to reduce these problems. This article reviews coatings to reduce bacterial adhesion and encrustation. In addition, metal ureteral stents, the triclosan and ketorolac drug eluting ureteral stents, and biodegradable ureteral stents are discussed. In summary there is no perfect ureteral stent that avoids all morbidity but there have been significant advances in the last few years in stent technology.
输尿管支架在泌尿科中广泛应用，但常与患者不适、支架结壳和支架相关感染相关。为了试图减少这些问题，已经设计了新的生物材料、涂层和设计。本文综述了减少细菌黏附和结壳的涂层。此外，还讨论了金属输尿管支架、三氯生和酮咯酸药物洗脱输尿管支架，以及可生物降解输尿管支架。总之，没有一种完美的输尿管支架可以避免所有的发病率，但在过去几年中，支架技术取得了重大进展。
