The exact mechanism by which the enteric bacteria like E. coli, Bacillus proteus, Pseudomonas aeruginosa, Aerobacter aerogenes cause urinary tract infection is not known but in majority of cases it is an ascending infection from perianal or periurethral region.

During infancy, the ratio of UTI in male and female children is equal but after infancy it is 4 to 6 times more common in female children. The high rate of incidence in female children is mainly due to short urethra.
