While standard commercially available pigtail ureteral stents are used commonly in the obstructed patient, particularly when metastatic disease has been identified, our recent experience suggests caution in the use of such stents for patients with ileal conduits. Rapid obstruction of these stents occurs with unacceptable frequency, which has resulted in urosepsis and death, and they do not appear to be cost-effective even for palliation. Although these standard pigtail stents have physical properties that allow easy placement by angiographic wire guidance, they are not to be recommended. Safe internal ureteral diversion in patients with an ileal conduit awaits further evolution in stent technology.
虽然标准的市售猪尾形输尿管支架常用于梗阻患者，尤其是在已确诊转移性疾病的情况下，但我们最近的经验表明，对于回肠代膀胱患者使用此类支架时应谨慎。这些支架快速梗阻的发生率令人难以接受，已导致尿脓毒症和死亡，而且即使是用于姑息治疗，它们似乎也不具有成本效益。尽管这些标准猪尾形支架具有便于通过血管造影导丝引导放置的物理特性，但不推荐使用。回肠代膀胱患者安全的输尿管内转流仍有待支架技术的进一步发展。
