Abstract

Introduction

While acute kidney injury (AKI) in pregnancy is currently a rare entity in developed countries, it is still a common occurrence in developing countries, representing a major cause of maternal and fetal morbidity and mortality. Scarce data are published regarding pregnancy-related acute kidney injury (PRAKI) in Middle Eastern and African countries. The aim of this work is to report on the frequency, the underlying causes, and the outcomes of patients with PRAKI in an Egyptian tertiary care hospital.

Methods

This is a prospective observational study that included 40 patients representing all women who presented to the Mansoura Nephrology and Dialysis Unit with PRAKI over two years. All patients were followed up for three months after hospital discharge to assess renal outcome, and till the end of pregnancy to assess the maternal and fetal outcomes.

Results

PRAKI was reported  in about 1% of women who presented to the obstetrics service, and accounted for 14% of all AKI patients who presented to the renal service in our hospital. Preeclampsia (PE) and obstetric hemorrhage were the commonest causes of PRAKI. Maternal mortality occurred in 22.5% of PRAKI patients. The majority of survivors (62.5%) fully recovered, while the remaining (37.5%) individuals became dialysis dependent. Unfavorable fetal events occurred in 24 pregnancies (60%).

Conclusion

In our hospital in Mansoura, Egypt, PRAKI represents a relevant burden with potential ominous outcomes obstetric hemorrhage and preeclampsia were the major causes. Further research is needed to understand the causes and improve the outcomes of pregnancy-related AKI.
