Urinary Tract Infections

  • Christopher L. Coogan


Urinary tract infections (UTI) are common and affect both men and women of all ages. The risk of a woman experiencing at least one UTI is approximately 40–50%. UTI’s occur less commonly in men as a result of their longer urethra and possibly bactericidal prostatic secretions. Bacteriuria refers to the presence of bacteria in the urine. The incidence of bacteriuria in pregnant women varies between 4–7%; approximately 25% will develop pyelonephritis if untreated. The incidence of bacteriuria markedly increases in the elderly with an approximate incidence of 20% in females and 10% in males over the age of 65. Pyuria refers to the presence of white blood cells in the urine. UTFs may be classified as uncomplicated or complicated, the latter occur in patients with anatomic or functional abnormalities, altered immune status, or infection with resistant organisms.
