Self-expanding metallic stents for the treatment of hydronephrosis were implanted in 12 ureters with malignant compression in 10 patients. In 3 ureters the stents were introduced percutaneously by a transrenal route; in 8 ureters introduction was transurethral and in one ureter by a combined route. Patency rate after 6 months was 90.9%. In all cases the stent was able to withstand pressure by the tumour for the remainder of the patient's life. In one patient there was incrustation of both stents after 30 weeks, in another patient the ureter was kinked between the level of the stent and the distal ureter due to growth of the tumour. In all cases it was possible to overcome the obstruction during the lifetime of the patient by the use of a stent or by combining the stent with a plastic endoprosthesis.
自膨式金属支架用于治疗肾积水，对10例患者的12条输尿管进行了恶性压迫植入。3条输尿管经皮经肾途径置入支架；8条输尿管经尿道置入，1条输尿管采用联合途径置入。6个月后的通畅率为90.9%。在所有病例中，支架在患者余生中都能承受肿瘤的压力。1例患者在30周后两个支架均出现结痂，另1例患者由于肿瘤生长，输尿管在支架水平与远端输尿管之间发生扭结。在所有病例中，通过使用支架或将支架与塑料内置假体联合使用，在患者生存期内均可克服梗阻。
