ABSTRACT:
The invention is based on an arrangement of a ureter split, a guide and an auxiliary splint, wherein a releasable connection between the guide and the hollow ureter splint is provided, which connects the ureter splint by being turned along with the guide, wherein after releasing this threaded connection the guide can be displaced in the longitudinal direction of the ureter splint in respect to it and, if required, can be completely pulled out. While avoiding a clamped connection as provided by the prior art, and in order for the physician to be able to correctly perform the required rotating movements of the arrangement around its longitudinal axis and in both directions of its longitudinal axis in the course of inserting the ureter splint into the ureter, it is first provided that the guide is in a threaded connection with the auxiliary splint, which forms a rotary connection in both direction of rotation between these two elements and is outside the body of the patient when the ureter splint is inserted, and that the guide can be rotated by a manually operated device in respect to the ureter splint and the auxiliary splint around the common longitudinal axis.
