This is an interesting question, B.. I would think that, if anything, her adenoids are waking her in the middle of the night, messing up her sleep. People who don't sleep well normally get up and go to the bathroom.
IF your daughter doesn't have speech problems, nasal speech specifically, then you should have her adenoids reduced at the very least. If she DOES have nasal speech, you need to talk to an ENT who works with speech impaired children. Removing adenoids in a child with nasality issues can cause them to have much worse nasality because the adenoids are a "roof" to the soft palate. You would want to make sure that your child doesn't have a hidden submucous cleft palate (my child does - that's how I know this) by having a nasal endoscopy done. I would NEVER allow an ENT to perform this surgery without doing a nasal endoscopy first.
So, first of all, give your daughter the gift of dealing with the adenoid issue. Get the ENT to do a nasal endoscopy to assess her STRUCTURE. It's really important. If he balks, go find another ENT. (I had to do that. THAT'S how we found out my son has a submucous cleft - by then he was 4 years old. We'd been dealing with his nasality for 2 years by then.) If there is no nasality, if his structure is normal, then go ahead and get those adenoids out. Trouble breathing during sleep is actually a health issue and will cause her so many ancillary problems in her life. It really needs to be addressed.
I would put all this above the issue with the bedwetting. Right now, be patient with that. Have her strip her bed and wash her own sheets and pajamas. Don't shame her in any way. DO have her own the problem instead of doing FOR her. She's certainly old enough.
Good luck with this - I feel for you and her over this adenoid issue. I'm glad ours is behind us!!
