Objective: To determine the incidence, causes and prognosis of pregnancy-related acute kidney injury (PR-AKI) in Chinese women.
Methods: From July 2004 to February 2013, 18,589 women of Han ethnicity who attended the Obstetrics and Nephrology Department of our tertiary hospital were investigated, and individuals meeting the PR-AKI criteria were included in the analysis. The WanFang, Chinese Science Journal, Chinese Knowledge, MEDLINE, EMBASE and Cochrane library databases were searched, and literature describing PR-AKI diagnoses with Chinese women as study subjects and a sample size of ≥5 were included.
Results: The incidence of PR-AKI was 0.1183% (22/18,589). Hemorrhagic shock (31.8%) and pre-eclampsia (severe, 18.2%) were the two most common causes of PR-AKI. Twelve women recovered completely, six women displayed persistent proteinuria and four women had an increased serum creatinine level at discharge. There were no cases of death. Twenty women demonstrated adverse pregnancy outcomes (90.9%), including eight cases of stillbirth (36.4%). In our literature review, 29 of 4,076 articles were included, and the incidence of PR-AKI in China was found to range from 0.02% to 1.84%. Pregnancy hypertension (49.2%) and postpartum hemorrhage (13.8%) were found to be the most common causes of PR-AKI in China. The prognosis improved in 81.9% of the patients, the renal function deteriorated in 4.5% of the patients and 13.6% of the patients died. The rate of stillbirth was 27.0%.
Conclusion: The maternal condition after active treatment was good, whereas the pregnancy outcomes were generally poor. Although the incidence of PR-AKI was relatively low, this finding is noteworthy. Further studies are thus warranted to improve maternal-fetal outcomes.

Background: Acute kidney injury (AKI) that develops during pregnancy results from pregnancy-induced hypertension, hemorrhage, and sepsis, associated with morbidity and mortality in the fetus and mother. This meta-analysis was conducted to evaluate the incidence of pregnancy-related AKI (PR-AKI) and adverse clinical outcomes.
Methods: PubMed and Scopus were systematically searched for studies published between 1980 and 2021.

Background: Pregnancy-Related Acute kidney injury (PR-AKI) is a global health problem with substantial maternal and fetal morbidity and mortality. However, little is known about the current situation in the developing world including African countries. Africa is the poorest continent per capita, and women from Sub-Saharan Africa alone account for 66% of the estimated global maternal deaths from preventable obstetric causes.

Despite significant improvements in inpatient and outpatient management, pregnancy-related acute kidney injury (Pr-AKI) remains an important risk factor for early and late maternal and fetal morbidity and mortality. There is a discrepancy between the incidence of Pr-AKI in developing and in developed countries, with the former experiencing a decrease and the latter an increase in Pr-AKI in recent decades. Whereas septic and hemorrhagic complications predominated in the past, nowadays hypertensive disorders and thrombotic microangiopathy are the leading causes of Pr-AKI.
