Abstract

Matthew P Kusulas and Andrew De Piero

A Urinary Tract Infection (UTI) is an infection of the urinary system including the urethra, bladder, ureters, and kidneys. UTIs are typically caused by flora from the colon, most commonly E. coli. Infants typically present with non-specific symptoms of fever, poor feeding, and irritability, while older children may have more classic symptoms. Boys are more likely to develop a UTI in the first year of life, while after the first year they are more common in girls. In boys, circumcision decreases the risk of UTI at all ages. Overall 3-5% of girls experience a UTI, usually within the first 5 years of life.
