经皮顺行放置输尿管支撑体已为常用的介入性尿路放射学技术,作者描述了一种简易的方法。先作一经皮肾造口术以便进入输尿管。若有肉眼血尿或感染,则应推迟放置支撑体,直到肾造口引流液变清晰,且用抗生素。将一支硬导丝,如0.038吋聚四氟乙烯包裹的Landerquist-Ring扭矩导丝或0.038时Amplatz超硬导丝导入膀胱,再将一支11F、45cm长、带有共轴引导器的套鞘沿导丝送入膀胱,然后撤出引导器与导丝。选用一支8.5F、适当长度的泌尿科输尿管软硅酮或Silitek Uropass支撑体套在0.038时导丝上。若使用软硅酮作 Transcutaneous transurethral ureteral support has been commonly used in interventional urography, and the authors describe a simple method. First for a percutaneous nephrostomy in order to enter the ureter. If gross hematuria or infection, it should be postponed placement of the support, until the renal ostomy drainage become clear, and with antibiotics. A hard guide wire, such as a 0.038-inch Teflon-wrapped Landerquist-Ring torque wire or a 0.038-hour Amplatz super-hard wire, is introduced into the bladder and an 11F, 45 cm long sleeve with a coaxial guide The sheath is advanced along the guidewire into the bladder and the introducer and guidewire are withdrawn. Choose a 8.5F, appropriate length of urinary ureteral silicone or Silitek Uropass support at 0.038 when the guide wire. If you use soft silicone for
