Maternal characteristics and renal function between
singleton and twin pregnancies
Maternal characteristics are shown in Table 1. In this study, maternal
age, pre-pregnancy body mass index, and nulliparity rate were not
significantly different between singleton and twin pregnancies. However,
the rate of fetal growth restriction was significantly higher in twin
pregnancies than that in singleton pregnancies (p < 0.001). A
comparison of maternal renal function between singleton and twin
pregnancies is presented in Table 2. The gestational age at blood test
were significantly earlier in twin pregnancies than that in singleton
pregnancies (p < 0.001).
Serum creatinine level was
significantly higher and eGFR was significantly lower in twin
pregnancies than that in singleton pregnancies (p < 0.001). In
addition, the rate of renal dysfunction was significantly higher in twin
than that in singleton pregnancies (7.9% vs. 2.6%; p <
0.001).
