Urinating while sleeping

We've taken Rascal, our 12 yr old spayed female, to the Vet 2x and spoken to them on the phone a few times and are getting conflicting answers from 3 vets in the same office. Blood work and initial urinalysis show normal levels and no infection. First vet started her on estrogen, but it's not working. Next vet said it could be psychological, which neither my wife or I believe. We've had her 11 years now & think this would've shown itself much earlier in life. Besides, it seems to happen while she's sleeping and she doesn't even know it's happening. Third vet suggested it could be a rare form of diabetes and that the treatment won't cure the peeing. I collected a morning urine sample today, which my wife is taking to the vet. They're going to see if Rascal is "concentrating" her urine. Anyone out there have any experience with something like this?
