As children grow older, females become more prone to these infections because their urethra is shorter, which makes it easier for bacteria to enter the tract. The infections themselves are not dangerous if treated correctly with antibiotics. Left untreated, UTIs can lead to a blocked ureter and serious bladder and kidney infections. A urine test will confirm the presence of an infection. In a newborn, a specimen will be taken by inserting a catheter into the urethra, collecting urine in a bag or, rarely, by inserting a needle into the bladder.
Older children can collect a sample when they urinate.
Sometimes a blood test may also be performed. If you're breast-feeding, you may need to offer extra bottles of water. Change your child's diapers frequently, especially after bowel movements. Keep the genital area clean. Encourage older children to empty their bladders completely and frequently.
