The course of pregnancy and the outcomes of labor in the combination of oligoamnion with a flattened shape of the fetal bladder

Abstract

Aim. To study pregnancy and the outcomes of labor in women with oligohydramnios and flattened fetal bladder. Materials and Methods . We retrospectively analysed childbirth histories of 100 women admitted to Belyaev Kemerovo Regional Clinical Hospital either diagnosed with oligohydramnios combined with a flattened fetal bladder or having normal pregnancy course (n = 50 per group). Results. Patients with oligohydramnios and a flattened fetal bladder more frequently had past medical history of pelvic inflammatory disease (60% versus 30% in healthy women, p = 0.001) as well as dilation and curettage (32% versus 10% in healthy women, p = 0.003). Such patients had higher rate of a urinary tract infections during pregnancy (26.0% versus 4.0% in healthy women, p = 0.001). Childbirth in this patient group was more frequently complicated by a discoordinated labor (40.0% versus 0% in healthy women, p = 0.001). Pathology examination of the placenta confirmed the high frequency of chronic inflammatory process and chorioamnionitis in patients with oligohydramnios and a flattened fetal bladder. Conclusion. Patients with oligohydramnios and a flattened fetal bladder are a risk group of urinary tract infections during pregnancy and chorioamnionitis.
