- Definition of asymptomatic bacteriuria: two consecutive voided urine cultures with ≥ 108 cfu/L of same organism +/- pyuria, and NO symptoms of UTI.
- Asymptomatic bacteriuria with uropathogens in pregnant women should be treated as it is associated with increased incidence of pyelonephritis, preterm labour, and low birthweight infants.
- Screening for bacteriuria recommended at 12-16 weeks gestation, or first prenatal visit if later than 12-16 weeks gestation.
- Post treatment urine cultures recommended 1 week after completion of treatment followed by monthly urine cultures for remainder of pregnancy.
