Yes, it is a Medronic implant for bladder control.
Again, let me state I made a huge mistake in my earlier post. I take MYRBETRIQ for bladder control, not gabapentin.
No, you do not have to lay down to see a urologist. The only time I had to lay down on my back was when they used a specific CT to measure residual bladder contents, and, with an explanation of your failed laminectomy, a urologist can work around that. The CT for residual bladder contents is a new technique; they had previous methods that they can go back to. Best of luck to you!
