1. A catheter system for delivery of a ureteral catheter in a ureter, comprising:
a ureteral catheter,
a pusher catheter to deliver the ureteral catheter at a desired location, and a releasable connection device, to connect, in an assembled state a distal end of the pusher catheter to a proximal end of the ureteral catheter,
wherein the catheter system comprises a first contrast agent channel to deliver, when desired, fluid contrast agent near a distal end of the ureteral catheter and a second contrast agent channel to deliver, when desired, fluid contrast agent near the proximal end of the ureteral catheter,
wherein the first contrast agent channel and the second contrast agent channel are separate channels, and
wherein the first contrast agent channel and the second contrast agent channel run at least partially through the pusher catheter.
