Pregnancy in advanced chronic kidney disease and end-stage renal disease

This article reviews the available literature about the incidence, outcomes, and the management of pregnancy in women with advanced chronic kidney disease (CKD) and end-stage renal disease (ESRD) who require renal replacement therapy.

Pregnancy in women with advanced CKD and ESRD can result in serious adverse maternal and fetal outcomes, but improved outcomes have been noted in recent years, likely secondary to intensified dialysis regimens. More intensive dialysis allows for the gentle removal of water, solutes, and uremic toxins, which theoretically results in near-normal maternal renal physiology, an improvement in placental blood flow, and therefore a better environment for fetal growth and development. As management remains complex, a close joint collaboration between the high-risk obstetrical team and nephrology is essential.

Pregnancy on dialysis is becoming a viable option for women with advanced CKD and ESRD who do not have immediate access to transplantation.
