作者对12例(15根输尿管)因恶性肿瘤多发转移和输尿管外源性梗阻伴明显肾积水者用内窥镜置入自膨胀支撑管治疗。男3例,女9例,年龄29～76岁。选择此方法的标准为:近期综合化疗,估计寿命至少6个月;应用双“J”支撑管或肾造瘘管肾脏仍无功能;临床症状严重伴有肾积水或血清肌酐升高者。这种器械为用符合医学标准的不锈钢合金丝编织成的装置,末端易屈,置入时支撑管在伸长的位置,当长度减小时,其直径增加(最大为7mm)、扩张。当支撑管留在所放置的部位时能使置入器械易退回。在X线监视下,对输尿管梗阻定位,并标明部位和长度,而后必须注意不移动病人或X线C-臂,通过6F橄榄头导管置入导丝并向上
The authors of 12 cases (15 ureters) due to multiple metastases and ureteral obstruction with significant hydronephrosis with endoscopic self-expanding stent placement. 3 males and 9 females, aged 29 to 76 years old. The standard of choice for this method is: the recent comprehensive chemotherapy, the estimated life expectancy of at least 6 months; application of double “J” support tube or kidney fistula renal still non-functional; clinical symptoms associated with hydronephrosis or serum creatinine increased. The device is a device made of stainless steel alloy wire conforming to the medical standard. The end of the device is easy to buckle. When placed, the support tube is in an extended position. When the length is reduced, the diameter increases (up to 7mm) and expands. When the support tube is left in place, the placement instrument can be easily retracted. Ureter obstruction was located under X-ray monitoring with location and length indicated, and care must then be taken not to move the patient or X-C-arm through the 6F olive catheter into the guidewire and up
