Conventional ureteral stents, which have been in use for almost 30 years, are undergoing several changes in materials, designs and purposes of use.
Recent advances in ureteroscopes reduced the numbers of double-J insertions. In addition, because of the frequent failures of the double-J stents in malignant obstructions of the ureter coiled metal stents, metal coil-reinforced stents and large-caliber self-expanding stents are being developed for such patients. In the near future, a new application will be stent-based drug delivery.
The conventional double-J stents and the concept of ureteral stenting is undergoing several changes. New generation stents will allow the physician to choose better-fitting stents according to the needs of the individual patient.
已使用近30年的传统输尿管支架在材料、设计和使用目的方面正经历多项变革。
输尿管镜技术的近期进展减少了双J管置入的次数。此外，由于双J支架在输尿管恶性梗阻中频繁失效，正在为这类患者研发螺旋金属支架、金属线圈强化支架和大口径自膨式支架。在不久的将来，基于支架的药物递送将成为一种新的应用。
传统双J支架及输尿管支架置入的概念正在经历多项变革。新一代支架将使医生能够根据个体患者的需求选择更合适的支架。
