The full metallic double-J ureteral stent (MS) was introduced as a method for providing long-term drainage in malignant ureteral obstruction. Experimental evaluation of the MS revealed that its mechanical features allow efficient drainage in difficult cases, which could not be managed by the insertion of a standard polymeric double-J stent. Clinical experience with the MS showed controversial results. Careful patient selection results in efficient long-term management of malignant ureteral obstruction. The use of the MS should also be considered in selected benign cases. Major complications are uncommon and the minor complications should not hinder its use. Experience in pediatric patients is limited and warrants additional study. The cost-effectiveness of the MS seems to be appropriate for long-term treatment. Further investigation with comparative clinical trials would document the outcome more extensively and establish the indications as well as the selection criteria for the MS.
全金属双J型输尿管支架（MS）被引入作为恶性输尿管梗阻长期引流的一种方法。对MS的实验评估表明，其机械特性使其能够在困难病例中实现有效引流，而这些病例无法通过插入标准的聚合物双J型支架来处理。MS的临床经验显示出有争议的结果。仔细选择患者可实现恶性输尿管梗阻的有效长期管理。在选定的良性病例中也应考虑使用MS。主要并发症并不常见，轻微并发症不应妨碍其使用。儿科患者的经验有限，需要进一步研究。MS的成本效益似乎适合长期治疗。通过比较临床试验进行进一步研究将更广泛地记录结果，并确定MS的适应症和选择标准。
