A UTI in a child can be easily diagnosed by a professional pediatrician (a kids doctor). Here at KidsHealth Pediatrics, our pediatrician Dr. Nabong is fully certified to diagnose and treat your child. If it turns out that your child has a UTI, we can provide the proper treatment. A UTI is treated with an antibiotic. A mild antibiotic can prevent the infection from spreading to the kidneys. Additionally, we will suggest that your child drinks a lot of fluids. For most of our young patients, antibiotics and plenty of fluids will do the trick!
