Re: Mirena coil - lost threads and its out of place
They should remove your Mirena under anaesthetic and if I were you I would insist on it.
There are good short anaesthetics now and you would be able to go home the same day.
The thread retrievers that they use are not much different from the instruments used to fit your coil and if they locate it on the scan then they shouldn't have to 'fish for it'.
Please try not to worry too much, it is a routine procedure and you will feel better when its out.
