An inter-ureter signaling device intended to provide a surgeon with a signal to identify when a ureter is grasped by a surgical clamping device, such as a pair of forceps, the device being comprised of a catheter, a signal generator, and wiring, such that when the catheter component of the device, having been inserted into a ureter, is compressed by the surgical clamping device an electrical circuit is closed and the signal generator generates a human perceptible signal, indicating that the clamp has been placed on the ureter.
