We had just started the procedure when the doctor asked for a second guidewire.After receiving the wire, he placed the wire then ran the semi-rigid ureteroscope over the wire.Once the scope was in place, he tried to remove the wire through the scope and at that point had a little difficulty in doing so.Once he was able to remove the wire he noticed that the wire had some places where the coating was chipped away.He looked around using the scope to verify that none had chipped off inside the patient but there was a lot of edema so he placed a stent.
