Epidemiologic data on the incidence of pyelonephritis are limited. A population-based study of acute pyelonephritis in the United States found overall annual rates of 15-17 cases per 10,000 females and 3-4 cases per 10,000 males. [5] In women aged 18−49 years, the estimated incidence is 28 cases per 10,000. [8]  At least 250,000 cases of pyelonephritis are diagnosed annually in the United States. The cost of treating acute pyelonephritis has been estimated to be $2.14 billion per year. [5]
