This article provides an overview of urinary tract infections (UTIs) in pregnant individuals, noting that they are common, affecting about 8% of pregnancies. UTIs in pregnancy range from asymptomatic bacteriuria to symptomatic cystitis and the more serious pyelonephritis, which can cause significant maternal and fetal complications such as preterm birth and low birth weight. The document emphasizes the importance of screening for asymptomatic bacteriuria, given that effective treatment can prevent progression to more severe infections. It discusses the physiological changes in pregnancy that increase susceptibility to UTIs and reviews current diagnostic and treatment approaches aimed at reducing adverse outcomes associated with these infections.
