Thanks. Of course, as a diabetic my first thought is always kidneys.
Third episode today - lasted only a few hours and the urine is again
clear. A urinary tract infection is unlikely to be episodic. Lack of
pain probably rules out a stone. I suppose the highest probability is a
blood vessel, but it's not in the urethra since color doesn't change
between beginning and end of the stream. That makes it kidney, ureter,
or bladder. I'm unhappy about this, but will see my doc on Tuesday.

Too bad there's no significant correlation with diabetes, or someone
would say "most cases of this sort are ............"

Again - thanks!
