| dc.description | Objective The aim of the present study was to establish
the normal range for fetal UPR in the Brazilian
population.
Methods A cross-sectional study was performed in 167
normal singleton fetuses with gestational ages ranging
from 20 to 40 weeks. UPR was measured using 3-D US
virtual organ computer-aided analysis (VOCAL). UPR (in
ml/h) was calculated during the filling phase by using the
equation UPR = (VFB2 - VFB1)/time. The values for
UPR were plotted as a function of gestational age to obtain
a nomogram. Interobserver reliability was also investigated
by using Spearman’s rank correlation for comparison of
paired samples in cases of replication between observers.
Bland and Altman’s graphical approach was utilized to
investigate the agreement between observers.
Results A total of 167 normal singleton fetuses with
gestational age between 20 and 40 weeks were investigated.
Nine of them were excluded because the image
quality was insufficient for correct visualization of the
bladder contour. Linear regression analysis of UPR as a
function of gestational age generated a curve that represents
the normal range for fetal UPR in the Brazilian
population, and is expressed by the equation: Ln
(UPR) = -13.7508 ? 0.7094 9 GA - 0.0092 9 GA2
(R2 0.60). A correlation coefficient of 0.9994 (Spearman)
was obtained. Bland and Altman’s graphic plots confirm
the significant agreement between observers.
Conclusion Small differences were observed between
the values for UPR observed in our sample and the
normal values described in previous studies. These
differences were observed mainly in late third trimester
and are probably related to population biometric
differences. | |
