What Causes Urinary Incontinence After Recovering From A UTI?

Hello, my daughter is turning 9 on Tuesday and a little later after we potty trained her she suffered a uti which we took her to the hospital and she was treated. Now ever since she pees herself only during the day never at night. She seems to never be able to hold her pee in day time. At night she s never had a problem. We have taken her to her doctor i fact we have changed doctors because they always tell her she will grow out of it or they just give her antibiotics. Now I m concerned because her pees smells like shrimp or fish and it s really strong. Is taking a toll on my family and on her because she s nine and feels she will be like this forever. Please help we don t know what else to do besides trying everything yo cranberry juice, antibiotics. Change of clothes. To the point that I ve taken her to the ER and they say she has no infection they don t understand why it smells and can t do anything because she shows no signs of infection or fever to say it s a UTI.
