Antepartum Urinary Tract Infection

Four to 8% of pregnant women will develop asymptomatic bacteriuria, and 13% will develop symptomatic cystitis with dysuria. Pyelonephritis develops in 25-30% of women with untreated bacteriuria.

I. Asymptomatic bacteriuria is diagnosed by prenatal urine culture screening, and it is defined as a colony count $ 105 organisms per milliliter. Patients with symptomatic cystitis should be treated with oral antibiotics without waiting for urine culture results.

A. Approximately 80% of infections are caused by Escherichia coli; 1015% are due to Klebsiella pneumonia or Proteus species; 5% or less are caused by group B streptococci, enterococci, or staphylococci.
