Cohort studies have found no adverse outcomes for older men or women associated with asymptomatic bacteriuria. Antimicrobial treatment studies for asymptomatic bacteriuria in older adults demonstrate no benefits and show increased adverse antimicrobial effects. Consensus criteria has been developed to characterize the specific clinical symptoms that, when associated with bacteriuria, define urinary tract infection. Screening for and treatment of asymptomatic bacteriuria is recommended before urologic procedures for which mucosal bleeding is anticipated.

Conditions: Bacteriuria, Urinary Tract Infection (UTI)

Diagnostic Tests: Urine Analysis (UA)

Procedures: Urologic Procedures, Cystoscopy

Treatments: Antimicrobial Treatment (Antibiotics)
