Main Findings
Multivariate analysis showed that twin pregnancy, nulliparity, and
preeclampsia were significantly associated with maternal renal
dysfunction during pregnancy. Although preeclampsia is clearly
associated with maternal renal dysfunction, the present study revealed
that twin pregnancy is a risk factor for maternal renal dysfunction.
However, there were no differences in maternal renal function based on
chorionicity. In the present study,
all 13 twin mothers with renal
dysfunction recovered to within normal limits during the postpartum
period.
