Causes of the Excessive Rates of Perinatal Mortality and Prematurity in Pregnancies Complicated by Maternal Urinary-Tract Infections

Abstract

The study was undertaken to determine the causes of the more frequent pre-term deliveries, fetal and neonatal deaths associated with maternal urinary-tract infections during pregnancy. The combined perinatal mortality rate for eight common placental and fetal disorders was 42 per thousand births in the infected vs. 21 per thousand in the noninfected, owing to a greater mortality from noninfectious placental and fetal disorders in the gestations with the urinary-tract infections (P<0.001).
