So far so good

 Mira's surgery went well. Her surgeon commented that her bladder was very thick, which, if you think about what you know about muscles (and the bladder is muscle tissue) means that her bladder's been working much harder than it ought to for quite a while now. We *knew* that (anyone who spends as much of her day trying to pee as Mira does is working harder than is normal), but it was a nice confirmation that this was a good time for the surgery to happen.

So many things that most of us take for granted - like the ability to coordinate the squeezing of one's bladder with the releasing of one's sphincter - are just really challenging when you have the degree of neurological disconnect that Mira has.

This should make a lot of things much more restful for her...and supposedly should be fairly complication-free (a hole in your abdominal wall sounds like a great way for infection to get in, but apparently because there's a continuous, low-volume flow *out*, contamination *in* isn't a big concern.)
