The incidence of pregnancy in patients with chronic kidney disease (CKD) undergoing hemodialysis is rare. For pregnant patients with CKD undergoing regular hemodialysis, the effects of renal disease on the fetus should be noted and require specific strategies. A 30-year-old woman had no menstruation for 4 months. Abdominal ultrasound showed single fetus within 16 weeks of pregnancy. She had previously been in regular hemodialysis twice a week since 2015, then the frequency of hemodialysis was increased to thrice a week for 4 hours/dialysis. During pregnancy, she was given erythropoiesis stimulating agent, controlled protein nutrition (0.6-1,5g/kg/day) and routine pregnancy controls to obstetrician. After 31-32 weeks gestation, baby was born alive with low birth weight (1800g). Maintaining pregnancy in women with regular hemodialysis is still challenging and difficult. Prolonged/intensive dialysis during pregnancy results in longer gestational periods, higher fetal weights, and a higher likelihood of survival. Based on a dialysis guideline for pregnancy in CKD, hemodialysis is performed at least 20 hours/week to maintain pre-dialysis of BUN≤50mg/dl, hemoglobin should be at least 10-11g/dL. We reported a case of pregnancy in dialysis CKD patient undergoing hemodialysis thrice a week (4 hours/dialysis). Baby was born alive with low birth weight (1800 g).
