Urinary Tract Infections
Urinary tract infections are common in young children. Normally, urine has no bacteria. When bacteria enter the urinary tract system, an infection can begin. Early diagnosis and treatment are important to prevent long-term problems. Bring along a urine sample if you are able to get one. It’s important to distinguish between urinary pain caused by local irritation versus infection. Vaginal yeast infections can also cause urinary pain.
Common Questions
- A strong, persistent urge to urinate
- A burning sensation when urinating
- Frequent, small amounts of urin
- Cloudy or strong smelling urine
- Pink or cola colored urine
A: We collect a sterile specimen from your child at the clinic. For infants and toddlers who cannot urinate into a cup, we use a small tube to insert into the bladder to obtain a sterile specimen. We do a rapid urinalysis with results in a few minutes. Based on the result, we may need to send the urine to the lab for a culture.
A: Most UTIs are treated with oral antibiotics. A child with a high fever may also need a shot. When a child has a fever or more severe symptoms, an antibiotic injection may be needed, which is available at After Hour Pediatrics.
