Idiopathic urinary findings and fetal growth restriction in low risk pregnancy

To determine whether maternal urinary findings in the first trimester of pregnancy are associated with fetal growth restriction.

The prevalence of urinary findings in singleton pregnancies complicated by fetal growth restriction were compared with a low-risk control group of pregnancies who gave birth to normal weight babies, in the same condition.

There were significant statistical differences in the mean gestational age (p < 0.001), isolated asymptomatic bacteriuria (p<0.001), hematuria (p = 0.002, OR = 6.6, CI = 1.8-24.2) and proteinuria (p = 0.016, OR = 4.1, CI = 1.2-13.3). There was no recognizable relation between ketonuria and fetal growth restriction.

Our data showed a relation between the increase of adverse pregnancy outcomes, including fetal growth restriction, and hematuria, proteinuria and asymptomatic bacteriuria. Appropriate monitoring of pregnant women using these findings may be helpful in the identification of more complications.
