Marci, it is a good thing that you are bringing Buddy in for a checkup. I am sure your vet will run all the usual tests. Also be sure to get a copy of the bloodwork and urinalysis. Tell them to send you a copy.
Vicky is right about the C & S, but even just the urinalysis should tell a good deal if it is a UTI. Since Buddy doesn't seem to be in any pain ("He doesnt feel sick, he's active , playful,purring, but eating and peeing alot") then maybe you can ask your vet to hold off on giving any meds until they have a definitive answer if this is indeed a UTI or not. Like checking the urine specifiy gravity which is pretty simple. From a post from Dr. Lisa:

The first thing that I do with ANY cat that is showing UT symptoms is to check the urine specific gravity.
If it is high (over ~1.035) the chances of having an infection are extremely slim.....ie....1% if the cat does not have sugar in its urine. (Sugar in the urine raises the chance that a bug *could* grow in concentrated cat urine.)
If less than 1.030, the chances of a cat showing FLUTD (feline lower urinary tract disease) signs go up to ~25%...depending on what study you read.
When Bennie (my Obesity project) had FLUTD signs (bloody urine...urinating frequently/small amounts...looking like he felt lousy..) he was too fat to do a cysto on so I just banked on the fact that his chances of having an infection with a USG of 1.45 were slim to none. He got buprinex and love....to decrease his stress level...and time. He was fine with in 2-3 days.
I encourage my clients to take a urine sample to the vet and have them do a quick USG check. You only need a few drops of urine."
But on the other hand, I think in your case Marci complete blood work would be a good thing here since it has been a year, plus doing the urinalysis. In addition you might have your vet check his teeth too.
Please tell him how frustrated you are in trying to get his blood glucose levels down and show him your spreadsheet too. Hopefully, he will try and work with you and will be interested in what you are doing for your Buddy.
Please let us know how it turns out, okay?
