Dear teedit,
I can certainly understand your anxiety. When you have a chronic illness like Diabetes, you really do worry about all the things that can go wrong, and of course Kidneys can be a major concern. I've learned a few things in my 39 years with diabetes and one is that you do have to stay on top of things and pursue the knowledge and answers that you need to help you understand and care for your diabetes. It sounds like you are already doing a good job of that. I have also learned that simply having a symptom doesn't necessarily mean you're doomed for the worst outcome, although I know that feeling.
It sounds like your kidneys are probably in good shape based on the tests your doctor has already performed. However, for your peace of mind and education, you may want to make an appointment with a nephrologist to learn more about your particular syptoms and also to learn more about diabetes and kidney disease in general. A nephrologist will be able to give you more detailed information about the progression of kidney disease and what symptoms you might be experiencing if you were really in trouble. At the very least, a nephrologist might be able to set your mind at ease, so that your energies can be spent on taking care of all the other things we diabetics have to do to get through the day. The bottom line is that good control is the best way to avoid complications and that's hard enough without adding the burden of worrying. I would encourage you to do whatever will lighten your worry load, so that you can keep up the good work of taking care of yourself.

teedit,
Thanks for your post. I've had diabetes for a long time, too, and am embarrassed to say I never knew that a bit o' foam/froth in our urine can be a symptom of protein.
I have had that very occasionally and also have routine kidney function tests that are always normal. Last time I had that, it was just after some outpatient surgery and I'd assumed it was the result of a more forceful stream. Your question & the answer now suggest I may've had some ketones during that post-op period.
Might there be anything else going on that might account for a temporary change in your urine? Additional exercise? Not enuf water this summer? Doing Atkins or similar high protein diet?
Good luck. I hope you'll let us all know what you find out if you do get a more thorough check with a nephrologist.
