Bluenurse - She didn't have the implantation during the test. This implantation is a "permanent" device that helps her void. Although, she said it doesn't completely work as well as she hoped it would.

Also, you are correct, the data is so important. I truly don't want to end up with kidney problems due to back flow. I know that by doing the test, should there be an issue, there are treatments for it. (Well, I know there is an issue but what is that issue is the big question.)
