目的 探讨对盆腔原发或转移性肿瘤合并尿路梗阻的患者动脉插管化疗前后采用经皮穿刺顺行输尿管支架置放术的技术方法及可行性。方法 对 7例恶性肿瘤伴输尿管狭窄的患者行经皮穿刺顺行放置输尿管支架 ,联合动脉插管化疗。随访时间 2～ 8个月 ,平均 5个月。结果 7例输尿管支架置放术均获成功 ,病人尿路梗阻解除 ,能耐受动脉插管的常规化疗剂量。 1例出现反复血尿及尿路感染 ,余 6例无严重并发症。结论 对恶性肿瘤导致输尿管狭窄、梗阻的病人在动脉插管化疗过程中顺行放置输尿管支架解除尿路梗阻 ,是一种简便、有效、可行、并发症少的介入治疗方法
Objective To investigate the technique and feasibility of transcutaneous percutaneous ureteral stent placement before and after arterial catheterization in primary pelvic or metastatic tumor with urinary tract obstruction. Methods 7 cases of malignant tumor with ureteral stricture were percutaneously placed ureteral stent, combined with arterial intubation and chemotherapy. Follow-up time of 2 to 8 months, an average of 5 months. Results All the ureteral stents were successfully placed in 7 cases. The urinary tract obstruction was relieved and the conventional chemotherapy dose that could tolerate arterial cannulation was obtained. 1 case of repeated hematuria and urinary tract infection, more than 6 cases without serious complications. Conclusion Malignant tumors lead to ureteral stricture, obstruction in patients with arterial catheterization chemotherapy placed ureteral stenting to clear the urinary tract obstruction, is a simple, effective, feasible, less complications of interventional treatment
