经皮顺行输尿管支架成形仍然是在逆行技术失败和医源性损伤后的首选方法。这种支架成形能够在输尿管恶性阻塞的病人作为一种姑息的措施或作为输尿管吻合病人的输尿管瘘或吻合失败的一种有效方法。恶性阻塞的姑息性缓解有几个难题。虽然输尿管支架成形可更理想地代替肾切开的导管慢性体外引流,但必须考虑有不足之处。尽管在技术上 Percutaneous translational ureteral stenting is still the preferred method after retrograde technique failure and iatrogenic injury. This stent can be used as a palliative measure in patients with malignant obstruction of the ureter or as an effective method of ureter fistula or anastomosis in patients with ureter anastomosis. Palliative relief of malignant obstruction has several challenges. Although ureteral stent formation may be a better alternative to chronic external drainage of a nephrectomy catheter, some deficiencies must be considered. Although technically
