Fifty-five pyelovesical endoprostheses were inserted percutaneously in 56 patients. The indication for this procedure was a benign disease in 22 cases and a malignant disease in 34 cases. Early complications were haemorrhagic (3 haematomas) and infectious (septicaemic syndrome: 2 cases). 80.6% of the stents remained patent and most of the obstructions occurred before the second month in the benign indications (mean: 4.1 weeks) and later (mean: 13 weeks) in the malignant indications. Two-stage insertion (nephrostomy then insertion of the endoprosthesis under conditions of sterile and non-haemorrhagic urine) decreased the risk of early occlusion of the stent by urinary debris and clots. Abundant diuresis and control of urinary tract infection by prophylactic antiseptic treatment contribute to the maintenance of the patency of the prosthesis.
56例患者经皮插入了55个肾盂膀胱内支架。该手术的适应证为良性疾病22例，恶性疾病34例。早期并发症为出血性（3例血肿）和感染性（败血症综合征：2例）。80.6%的支架保持通畅，大多数梗阻在良性适应证中发生在第二个月之前（平均：4.1周），而在恶性适应证中发生较晚（平均：13周）。两阶段插入（先做肾造瘘，然后在无菌和无血尿的情况下插入内支架）降低了支架被尿液残渣和血凝块早期阻塞的风险。大量利尿以及通过预防性抗菌治疗控制尿路感染有助于维持支架的通畅。
