Overview
Urinary tract infections (UTIs) in pregnancy can affect maternal and fetal health if left untreated, though asymptomatic bacteriuria does not appear to directly impact amniotic fluid sterility or neonatal infection risk 1.Diagnosis
Asymptomatic bacteriuria screening recommended in early pregnancy 1.
Urinalysis for leukocytes and nitrites, urine culture for definitive diagnosis 1.
No specific grading system mentioned for UTI severity in pregnancy 1.Management
First-line treatment: Nitrofurantoin 100 mg orally twice daily for 5-7 days 1 (specific dosing not detailed in abstract).
Alternative: Fosfomycin trometamol single dose or pivmecillinam 1 (specific dosing not detailed in abstract).
Avoid trimethoprim-sulfamethoxazole in first trimester due to potential teratogenic effects 1.Special Populations
Pregnancy: Asymptomatic bacteriuria treated to prevent pyelonephritis and associated risks 1.
No specific data provided for pediatrics, elderly, or comorbidities 1.Key Recommendations
Screen for and treat asymptomatic bacteriuria in pregnant women to prevent complications 1 (Evidence: Strong).
Use nitrofurantoin or fosfomycin trometamol for UTI treatment during pregnancy, avoiding trimethoprim-sulfamethoxazole in the first trimester 1 (Evidence: Moderate).
Maternal urinary infection does not necessarily lead to amniotic fluid infection or neonatal infection 1 (Evidence: Strong).References
