EROSION of TVT AGAIN!!! HELP!

In July, 2008 I had a surgery of TVT, tubal and ablasion.  October my husband felt something sharp during intercourse and so I went into the doctor and he told me I fell into that 1% of women that have erosion.  He performed an in office operation to cut around, resecure, and re-stitch and said he fixed it and it shouldn't happen again as he provided many layers over the area.  Well now, 2 months later, it has happened again.  He told me to come back in to take a look, but I would like to know what my options are.  Please help.  Do I have him resecure it again?  I have terrible insurance and can't have this keep happening.

Any advise would be greatly appreciated.

Thank you!
