Uncomplicated pyelonephritis is not a fatal disease in the antibiotic era. Pyelonephritis becomes a potentially fatal disease when secondary conditions develop, such as emphysematous pyelonephritis (20-80% mortality rate), perinephric abscess (20-50% mortality rate), or one of the sepsis syndromes (>25% overall mortality rate).
