Recently (last Two Days) I Have Noticed My Urine Is

Recently (last two days) I have noticed my urine is yellow. Not the deep kind yellow when dehydrated but brighter light yellow. After prostate surgery in DEC had a couple of UTIs but this looks a little like pineapple juice without any burning or other symptoms. Have final followup with surgeon in early May and would like to get some ideas before then. Drink filtered water and little else besides a small glass of milk before bed. Any ideas? Thanks Really enjoy getting WEB MD.
