Asymptomatic Bacteriuria

should not be treated and asymptomatic patients including diabetics, the elderly and those with catheters should not be screened for bacteriuria.
Do not screen or treat asymptomatic bacteriuria in the following conditions (strong evidence):

• women without risk factors;
• patients with well-regulated diabetes mellitus;
• post-menopausal women;
• elderly institutionalized patients;
• patients with dysfunctional and/or reconstructed lower urinary tracts;
• patients with renal transplants;
• patients prior to arthoplasty surgeries;
• patients with recurrent urinary tract infections.

It is recommended that pregnant women with ASB [≥103 colony forming units (cfu)] should be treated, however the evidence for this practice is low. Treat as for uncomplicated cystitis but avoid fluoroquinolones.
