Asymptomatic Bacteriuria

Asymptomatic bacteriuria or asymptomatic UTI is the isolation of a specified quantitative count of bacteria in an appropriately collected urine specimen obtained from a person without symptoms or signs of urinary infection. Asymptomatic bacteriuria is common but its prevalence varies widely with age, gender, and the presence of genitourinary abnormalities or underlying diseases. For example, the prevalence of bacteriuria increases with age in healthy women from as low as about 1 % among school girls to greater than or equal to 20% among women 80 years of age or older living in the community while bacteriuria is rare in healthy young men.13 Because its clinical significance was controversial (asymptomatic bacteriuria precedes UTI but does not always lead to asymptomatic infection), guidelines were recently published for the diagnosis and treatment of asymptomatic bacteriuria in adults older than 18 years of age.13 The foundation of these guidelines rests on the premise that screening of asymptomatic subjects for bacteriuria is appropriate if bacteriuria has adverse outcomes that can be prevented by antimicrobial therapy. Thus, screening and treatment for asymptomatic bacteriuria was recommended for pregnant women (because the risk of progression to severe symptomatic UTI and possible harm to the fetus), males undergoing transurethral resection of the prostate, and individuals undergoing urologic procedures for which mucosal bleeding is anticipated. In contrast, screening for or treatment of asymptomatic bacteriuria was not recommended for premenopausal, nonpregnant women, diabetic women, older persons living in the community, older institutionalized subjects, persons with spinal cord injury, or catheterized patients while the catheter is in place.
