My 15 year old is having this surgery done to fix a blocked kidney. Although I'm no "newbie" when it comes to watching her kids have surgical procedures, I'm still kinda freaked out by this. I guess it's the 4 hour time frame for her surgery. But I know she will be fine. But I am curious as to the recovery. How long can I expect her to be out of school? She will have a stent in for 6 weeks, but she's had one before, so not too worried about that.
