UTIs are managed more aggressively in pregnant women than in non-pregnant women. Other antibiotics have not been extensively researched for use in UTIs, and further studies are necessary to determine whether a shorter course of other antibiotics would be as effective as the traditional treatment length. Beginning in week 6 and peaking during weeks 22 to 24, approximately 90 percent of pregnant women develop ureteral dilatation, which will remain until delivery hydronephrosis of pregnancy.

Urinary tract infections are common during pregnancy, and the most common causative organism is Escherichia coli. A study from the Centers for Disease Control and Prevention CDC found that about 4 in 10 women with UTIs during early pregnancy filled a prescription for nitrofurantoin or trimethoprim-sulfamethoxazole.
Not all urine infections cause symptoms. Group B streptococcus: Pregnancy, pyelonephritis and prematurity. Although trimethoprim is commonly used to treat symptomatic UTIs, good evidence to support its use in pregnancy is lacking.
The gold standard for detection of bacteriuria is urine culture, but this test is costly and takes 24 to 48 hours to obtain results. Want to use this article elsewhere? They have also been linked with higher rates of low birth weight of the baby and premature birth baby is born much sooner than the expected date. Pregnant women are at increased risk for UTIs.
Asymptomatic bacteriuria is common, with a prevalence of 10 percent during pregnancy. Asymptomatic bacteriuria in pregnancy Asymptomatic bacteriuria during pregnancy has been associated with an increased risk of pre-term delivery and low birth weight.
Make a comment: The maternal and neonatal complications of a UTI during pregnancy can be devastating. ACOG educational bulletin no.
Antibiotic choice, as in asymptomatic bacteriuria, should focus on coverage of the common pathogens and can be changed after the organism is identified and sensitivities are determined. Your doctor will send a sample of your urine to the laboratory to be tested. Group B streptococcal GBS vaginal colonization is known to be a cause of neonatal sepsis and is associated with preterm rupture of membranes, and preterm labor and delivery. A prospective study of group B streptococcal bacteriuria in pregnancy.
This comment will be removed. The American College of Obstetrics and Gynecology recommends that a urine culture be obtained at the first prenatal visit. It is then recommended that urine cultures are repeated regularly until delivery.
