On 24 reno-ureteral units of 21 patients with a silicon ureteral stent, urodynamic study of the upper urinary tract was performed by diuresis radionuclide urography (DRU). We obtained the following conclusions. 1. A silicon stent was useful to maintain urinary stream in ureteral operation. 2. In extrinsic ureteral stricture due to pelvic malignant tumor, pattern of DRU was still poor after indwelling stent. 3. When a stent of the 5-8F's outer diameter was used for an adult, a too thick stent for the ureteral size might rather interrupt the urinary stream. 4. Patterns of DRU and GFR measured by Gates' method in the state of ureteral stenting could warns that hydronephrotic kidney may develop.
在21例留置硅输尿管支架的患者的24个肾输尿管单元上，通过利尿放射性核素尿路造影（DRU）对上尿路进行了尿动力学研究。我们得出了以下结论。1. 硅支架在输尿管手术中有助于维持尿流。2. 对于盆腔恶性肿瘤所致的输尿管外源性狭窄，留置支架后DRU图像仍较差。3. 当使用外径为5-8F的支架用于成人时，对于输尿管尺寸来说过粗的支架可能反而会阻断尿流。4. 在输尿管支架置入状态下，通过Gates法测量的DRU图像和GFR可提示可能会发生肾积水。
