目的探讨逆行留置输尿管内支架管 (双 J管 )的应用范围。方法介绍两种留置输尿管内支架管的方法 ,并总结分析 18例留置内支架管的治疗效果。结果输尿管梗阻均被解除 ,肾积水改善或消失 ,为手术、体外震波碎石术解除梗阻原因创造了条件 ,延长了肿瘤晚期致输尿管梗阻者的生命。结论逆行留置输尿管内支架管治疗效果肯定 ,操作简便 ,除肿瘤浸润输尿管、输尿管完全梗阻及插管困难外的各种输尿管梗阻都有应用价值。
Objective To investigate the application of retrograde ureteral stent (double J tube). Methods Two methods of indwelling ureteral stent were introduced and the curative effect of 18 indwelling stent was analyzed. Results Ureteral obstruction was relieved, hydronephrosis improved or disappeared, which provided conditions for surgery and extracorporeal shock wave lithotripsy to relieve the obstruction, prolonging the life of patients with ureteral obstruction at later stage of tumor. Conclusion Retrograde ureteral stent in the treatment of positive results, easy to operate, in addition to tumor infiltration of the ureter, complete ureteral obstruction and intubation of a variety of ureteral obstruction have application value.
