Hi-while I can’t speak from Dr. Poppas’ pov, our daughter did have the surgery when she was 6 months so it may be a bit different for a 2.5 yr. old. That said, we checked into the hospital the day before and had a few basic tests and they did start to up her doses of cortef at that point. I recall the toughest thing was no food after 10p or so as her surgery was scheduled for first thing the next day. The morning of we went to pre op and were with her and the surgeon and nurses were very nice and so forth. When they toolk her away and put her under, we were not there but indeed they did give her the big dose at that point if memory serves. The waiting was very difficult however the nurses kept us very much informed letting us know all was well. That was key and hopefully you will have the same info flow. When she came out of surgery she was just starting to wake up and it was important for us to be there as she awoke. She was not in pain (not crying at least) although she was groggy which of course wore off. She had a catheter in her urethra which she had to keep in for a couple of weeks. On the area that was worked on she had a few pieces of guaze which were held in place by a internal diaper. That was to catch her poop and had an external diaper in which the catheter flowed into. So for 2 weeks she had the double diaper. Her surgery was on a wednesday and we were sent home on Friday afternoon as she healed great. The stitches used eventually disintergrated so she did not have to have them taken out. She did have to have a follow up procedure - outpatient - that took a couple of minutes to get the catheter out but did have to go under again for that albeit for a few minutes only. I’m not sure if your daughter is toliet trained but the great thing was having her in diapers as she could not touch the catheter or the healing area. It was a pain dealing with the double diapers but seems so minor now looking back and how great she has healed. Good luck.
