✦ Synopsis

Objective:

Abnormalities of amniotic fluid (af) volume are associated with significant perinatal morbidity and mortality. although current ultrasound techniques provide a linear amniotic fluid index (afi) or 2-d area of af, these indices have limited correlation with actual af volume. the bladder volume instrument (bvi) 2500 ultrasound (diagnostic ultrasound corp., redmond, wa) utilizes a rotating 2 mhz transducer, a computer-defined fluid interface, and computer integration of 12 cross-sectional images to calculate 3-d fluid volume. in term pregnancies with normal af volume, we previously demonstrated a correlation between the afi and the 3-d volume as determined by bvi. in the present study, we sought to establish normative gestational values for bvi-determined 3-d volume and the relation to simultaneous afi determinations.

Methods:

Following written informed consent, 73 gravidas (17-41 weeks) with uncomplicated pregnancies and normal
