Since you are questioning your vet's assessment, rather than asking here, I think your turtle would benefit from a second opinion from another qualified herp vet. From the pics, I do think that paunch/swelling is abnormal given amount of food you say you're giving him. About the swelling---does it move at all, meaning, if you hold him and tilt him downward, does it move as fluid would move from one spot to another? How long has it been since your vet saw your turtle---if it's been a little while, would the swelling be more noticeable to your vet now?
I'm assuming your vet concluded it was gout at least in part because of the level of urea in the blood and x-rays of the joints(?). Does your turtle have trouble moving around and getting on the basking area? From what I know, swelling (usually of a joint) is often associated with gout...
You're right about lowering the amount of dietary protein---gout (and arthritis, which often accompanies it) is often associated with excessive protein intake. I don't know the protein content of Trout Chow, but Reptomin is rather high, as is Mazuri. If the protein content of the Trout Chow is lower and he'll eat it, then I'd give him that. Some other decent pellets are lower in protein as well (look for RepCal pellets, for example); you could alternate them with the other pellets. I can't really say anything about the sweet potato except that 1 gram is about 0.035 ounces, which doesn't sound like a lot to me. If the medication is helping him and that's the only way he'll take it, then I'd give it to him in the sweet potato (have you tried squash as well?). Will he eat other plant matter as well?
I don't want to worry you, but very simply, gout is a metabolic disorder that allows uric acid/urate to accumulate in the blood and tissues. Uric acid that is deposited in the kidneys may produce renal failure. One sign of renal failure is excessive fluid retention...
I would really seek out another opinion, especially since from what you say the "swelling" is not improving and alarm bells seem to be going off in you. At the very least, I'd try to get the vet who's seen your turtle to take a closer look at the swelling. Good luck.
