ABSTRACT:
A device for the insertion of a ureter into the ureter or renal pelvis has a ureter tube with an opening of its distal tip, an auxiliary tube and a mandrin. In the insertion position, at least the ureter tube and mandrin are releasably connected. A connecting-piece at the proximal end of the mandrin makes an injection of an X-ray contrast medium into the hollow space inside the mandrin possible where it passes to an outlet opening at the distal end of the mandrin which outlet opening has an entry to the ureter. The mandrin preferably has an inherent curvature in its distal tip and a moveable steering wire can be placed into the lumen of the mandrin.
