Abstract
Background: Successful pregnancy outcomes in patients with advanced chronic kidney disease (CKD) are increasingly common in Western countries. However, in Korea, the available literature addressing this clinical issue is scarce.

Methods: We reviewed 5 successful parturitions [1 patient with Stage 5 CKD and 4 with maintenance hemodialysis (HD)] at Seoul St. Mary's Hospital over 3?years and investigated changes in dialysis prescription, anemia management, and the incidence of maternal and neonatal complications.

Results: There were no maternal or neonatal deaths in this cohort. The mean age at the time of conception and delivery was 35.8?¡¾?3.7 and 36.2?¡¾?3.5 years, respectively. Dialysis patients received more frequent and intensified HD during pregnancy, 20.0?¡¾?5.7?h/wk of HD over 5 visits with the ultrafiltration dose maintained between 1 and 2?kg per session. All patients received erythropoietin-stimulating agents and iron replacement therapy during pregnancy. The mean hematocrit was 33.1?¡¾?1.9% before pregnancy and was well maintained during gestation (33.9?¡¾?3.8% at the first trimester, 29.2?¡¾?4.2% at the second trimester, and 33.6?¡¾?8.7% at delivery). The mean gestation period was 32.7?¡¾?4.7 weeks, with 60% of patients experiencing premature delivery. The primary maternal complication was pre-eclampsia; 3 women developed pre-eclampsia and underwent emergency cesarean sections. Most neonatal complications were related to preterm birth.

Conclusion: Dialysis-related care and general clinical management improved the clinical outcome of pregnancy for patients with advanced CKD.
