Epidemiology In men, roughly 2-3 cases per 10,000 are treated as outpatients and 1 in 10,000 cases require admission to the hospital. In women, approximately 12–13 in 10,000 cases are treated as outpatients and 3-4 cases are admitted to a hospital. The most common age group affected by Xanthogranulomatous pyelonephritis is middle-aged women. Infants and elderly are also at an increased risk because of hormonal and anatomical changes.
