Pregnancy outcomes after kidney transplantation - A single-center experience in Taiwan

Objective: This study investigated the pregnancy outcomes of women who had undergone kidney transplantations from 1992 to 2013 in a single medical center. Materials and Methods: Records for patients who had undergone kidney transplantations between 1992 and 2013 at National Taiwan University Hospital, Taipei, Taiwan were retrospectively reviewed, and data on obstetric conditions, neonatal outcomes, and maternal and neonatal complications were collected. Results: Data for a total of 15 pregnancies in 13 women who had undergone kidney transplantation between 1992 and 2013 were included in this study. The live birth rate was 87%. The mean gestational age was 35.4 +/- 3.2 weeks, and the mean birth body weight was 2208.8 +/- 678.8 g. Forty percent of the neonates were small for their gestational age (< 10th percentile); 53.3% of the pregnancies resulted in preterm deliveries (< 37 weeks); and 26.7% of the neonates needed Neonatal Intensive Care Unit admission. The prevalence rates of preeclampsia and gestational diabetes were 23.0% and 13.3%, respectively. Conclusion: The pregnancy outcomes after kidney transplantation were favorable and the mean birth body weight was 2208.8 +/- 678.8 g at 35.4 +/- 3.2 weeks gestational age. However, the maternal and neonatal complication rates were still high, such as preterm labor, preeclampsia, and small for gestational age.
