Urinary tract infections.

Urinary tract infection (UTI) is the most common urologic disorder and one of the most common conditions for which physicians are consulted. Patients at increased risk for UTI include women; diabetics; the immunocompromised; and those with anatomic abnormalities, impaired mobility, incontinence, advanced age, and instrumentation. Antibiotic therapy aims to relieve symptoms and prevent complications such as pyelonephritis and renal scarring. Distinguishing asymptomatic bacteriuria from a UTI can be difficult, especially in those with comorbidities. Most experts do not recommend screening for UTI, except in the first trimester of pregnancy. Copyright (c) 2010 Elsevier Inc. All rights reserved.
