Ureteral metal stents (MSs) present a minimally invasive tool to preserve the drainage of renal pelvis whenever ureteral patency is at risk to be obstructed due to extrinsic or intrinsic etiologies. Clinical experience with these stents demonstrates that they impose a promising alternative treatment option in ureteral pathologies that are difficult to be treated via common polymeric stents. Current application of MSs in the treatment of both benign and malignant ureteral obstruction reveals quite promising results. Nevertheless, the ideal MS that would provide uncomplicated long-term effectiveness is still lucking and current MS usage is facing several adverse effects between which stent obstruction, encrustation, infection, migration, and patient discomfort. Ongoing attempts to create more inert stent with sophisticated novel designs are expected to improve current MS efficiency. MSs will play a major role in the future as a routine management of a variety of ureteral pathologies.
输尿管金属支架（MSs）是一种微创工具，当肾盂引流因外在或内在病因有受阻风险时，可用于保持肾盂引流。这些支架的临床经验表明，在难以通过普通聚合物支架治疗的输尿管病变中，它们是一种很有前景的替代治疗选择。目前MSs在治疗良性和恶性输尿管梗阻方面的应用显示出相当有前景的结果。然而，能提供简单长期疗效的理想MS仍未出现，目前MS的使用面临多种不良反应，包括支架梗阻、结壳、感染、移位和患者不适。通过先进新颖设计制造更惰性支架的持续尝试有望提高当前MS的效率。MSs作为各种输尿管病变的常规管理手段，未来将发挥重要作用。
