Use of Renal Replacement Therapy in Pregnant Women with Acute Kidney Injury or Chronic Kidney Disease: A Systematic Review

Objectives. Acute Kidney Injury (AKI) during pregnancy is a complication that poses a serious risk of life for the
mother and the fetus. In most cases, the treatment considered in the first instance is pregnancy interruption with subsequent conventional treatment of AKI. The aim of this review is to describe the risks and benefits of using renal replacement therapy [peritoneal dialysis (PD) and hemodialysis (HD)] in pregnant patients with AKI.

Methods. A systematic review of pregnant women with AKI/CKD on RRT (pointing out the results of maternal and neonatal morbidity and mortality) in the last three decades was done between January and March 2021 using the databases Pubmed, LILACS, Cochrane, Tripdatabase, AJKD, and Elsevier. Articles in Spanish, English, and French languages were included. A summary of cases of pregnant women on RRT with women and fetus survival percentages was shown in a table.

Results. Making a summary of all the included patients, it resulted in 1673 women, 1208 in HD and 170 in PD with 15 maternal deaths and survival percentages for the fetus of 74% in HD and 40% in PD.

Conclusion. The RRT in pregnant women with AKI/CKD offers a high survival rate for the women and fetus.
