Urinary Tract Infection in Pregnancy
Key Points
Asymptomatic bacteriuria, UTI, and pyelonephritis increase risk of preterm labor and premature rupture of the membranes. Initially treat withcephalexin,nitrofurantoin, ortrimethoprim/sulfamethoxazole. Obtain proof-of-cure cultures after treatment. For women who have had pyelonephritis or more than one UTI, consider suppressive therapy, usually withtrimethoprim/sulfamethoxazole (before 34 weeks) ornitrofurantoin.
