A pregnant woman was performed hemodialysis 3 times a week from early gestation. At 30 weeks of gestation, fetal growth and amniotic fluid volume were normal. We performed 3-hour hemodialysis 6 times a week. Cesarean section was performed at 38 weeks of gestation, she delivered a healthy neonate weighing 2575 g. During hemodialysis, we performed Doppler flow velocimetry on the umbilical artery. The resistance index revealed a remarkable decrease after 1.5 hour hemodialysis. But it recovered 3 hours of administration as well as after completion of treatment. We speculated this change in the resistance index of the umbilical artery was caused by transient maternal hypovolemia.
