Abstract

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 ureterl stenting could warns that hydronephrotic kidney may develop.
