- EAU definition “without urinary tract symptoms…mid stream sample showing > 105 cfu / mL in 2 consecutive samples in women, or one single sample in men”
- As low as 102 in catheterised samples
- Screening and treatment for bacteriuria is not recommended
- 15 – 50 % incidence in nursing home patients
- Patients with long term catheters, those who self catheterise, or those with reconstructed urological tracts will often be colonised with asymptomatic bacteriuria, with no proven benefit in treating
- Worth screening and treating in:
- Pregnancy – 4 – 7 % incidence (similar to non pregnant women) but 20 – 40 % progress to pyelonephritis if untreated
- Prior to urological surgery
