对于恶性外源性输尿管梗阻（MEUO），逆行输尿管支架或经皮肾造口术的适应症仍存在争议。我们回顾性分析了53例使用逆行输尿管支架进行MEUO减压的患者。53例患者中有18例（34%）输尿管支架失败。多因素分析显示，胃肠道肿瘤为原发疾病、术前运动状态不佳、术前严重肾积水是支架失效的独立预测因素。在此基础上，提出了一种MEUO管理算法。
There is still controversy surrounding the indications for performing either a retrograde ureteral stent or percutaneous nephrostomy to manage malignant extrinsic ureteral obstruction (MEUO). We retrospectively analyzed 53 patients who underwent a decompression of MEUO using retrograde ureteral stent. Ureteral stent failure occurred in 18 of 53 patients (34%). Multivariate analysis showed that gastrointestinal cancer as the primary disease, poor preoperative performance status and severe preoperative hydronephrosis were independent predictors of stent failure. Based on the present data, we propose an algorithm for the management of MEUO.
