Y1 - 2009 N1 - T2 - CURRENT Diagnosis & Treatment: Nephrology & Hypertension AB - Urinary tract infections (UTIs) result in 3.6 million office visits each year and greater than 100,000 hospital admissions in the United States annually. They may be confined to the lower urinary tract resulting in cystitis or involve the upper urinary tract and cause pyelonephritis. This is an important distinction as pyelonephritis may result in renal parenchymal damage, urosepsis, and death. Enteric or coliform bacteria are responsible for most UTIs with Escherichia coli being the most commonly identified organism. UTIs are further divided into (1) uncomplicated UTIs, where there is no structural or anatomic abnormalities of the urinary tract, and (2) complicated UTIs, where they may be either structural or anatomic abnormalities of the urinary tract or functional predispositions to infection. In addition, microorganisms in patients with complicated UTIs are frequently multidrug resistant.
