Sorry to hear about your frog and your temporarily absent vet

One of my Hyla versicolor had a prolapse over a year ago, I found some great info at Frank Indiviglio's blog: Amphibian and Reptile Emergencies Read the comments as well. There's handy info contained in them, especially about a lengthy fast during the recovery phase which I hope you will get into. Definitely no food for the foreseeable future, even if it decides to go back in on it's own.

I had some luck with the sugar bath approach to dehydrate the exposed tissue, and I was fortunate to be able to gently nudge it back in with a q-tip lubed up with K-Y jelly

Best of luck.
