The article discusses the high incidence and risks of urinary tract infections (UTIs) in pregnant women. Due to physiological and anatomical changes during pregnancy, such as the dilation of the urinary tract and compression of the ureters, the risk of UTIs increases significantly. UTIs can be asymptomatic, present as cystitis, or progress to pyelonephritis, each with its own complications and treatment needs. The main complications associated with UTIs in pregnancy include preterm birth, low birth weight, anemia, renal insufficiency, and systemic infection, affecting both the mother and the newborn. The article emphasizes the importance of early screening and treatment to prevent these complications, recommending urine culture tests at the beginning and throughout pregnancy.
