With an insidious onset and a rapid progression, pregnancy-related acute kidney injury (PR-AKI) is an important cause of adverse maternal and infant outcomes and fatal complications in obstetric patients. A unique physiologic environment of pregnancy brings great challenges to clinical practices of nephrologists and obstetricians. With a recent liberalization of national two-child policy and a rapid development of assisted reproductive technology, there has been a growing number of elderly and high-risk women in labor. It is imperative to raise the awareness of PR-AKI. This review focused on the research advances in the outcomes of PR-AKI to provide references for clinicians to better understand the maternal-fetal outcomes of PR-AKI, identify which women are at a higher risk of poor prognosis and develop strategies for optimal managements and treatments.

Abstract Background Pregnancy-related kidney injury contributes to a high burden of acute kidney injury in low-resource settings and causes maternal and perinatal morbidity and mortality. Few studies have examined the impact of acute kidney injury in resource-limited countries, with very limited research on pregnancy-specific disorders in Ethiopia. This study aimed to determine the characteristics of pregnancy-related acute kidney injury, outcomes and associated factors. Methods A retrospective study was conducted to evaluate the clinical profile and maternal-fetal outcome of pregnancy-related acute kidney injury at Ayder Comprehensive Specialized Hospital in Tigray, Ethiopia, from January 1, 2017, to December 31, 2021. Maternal and fetal outcomes were analyzed using descriptive statistics. Multivariate logistic regression was used to determine the association between the dependent and independent variables. Results Of 27,350 mothers who delivered at Ayder Comprehensive Specialized Hospital between January 1, 2017, and December 31, 2021, a total of 187 women developed pregnancy-related acute kidney injury, a prevalence rate of 68 per 100,000 births. Preeclampsia, sepsis and pre-renal causes due to dehydration and hemorrhage were the most common causes of pregnancy-related acute kidney injury in this study. Hemodialysis was needed in 8.6% (n = 16) of patients. Of the 187 pregnancy-related acute kidney injuries, 143 (76.5%) recovered completely and 30 (16%) partially. The mortality rate was 7.5%. Preexisting chronic kidney disease (AOR = 30.13; 95% CI: 2.92, 310.84), use of vasoactive agents (AOR = 5.77; 95% CI: 1.47, 22.67), increase in creatinine per unit (AOR = 1.65; 95% CI: 1.11, 2.45) and complications related to acute kidney injury (AOR = 5.26; 95% CI: 1.73, 16.00) were determinants of the composite endpoints (partial renal recovery and death). Conclusions This study emphasizes acute kidney injury in resource-limited settings is a significant cause of maternal and fetal morbidity and mortality. The vast majority of patients with pregnancy-related acute kidney injury recovered completely from kidney injury. The main causes of pregnancy-related acute kidney injury were preeclampsia, sepsis and pre-renal associated with hemorrhage and dehydration. Preexisting renal disease, use of vasopressors, increase in creatinine per unit and complications associated with acute kidney injury were determining factors for concomitant fetomaternal mortality. Appropriate preventive strategies during prenatal care and prompt treatment are needed for pregnancy-related acute kidney injury.

Pr-AKI can arise from various obstetric complications, such as hyperemesis gravidarum, septic abortion, hypertensive disorders of pregnancy, pyelonephritis, and antiphospholipid antibody syndrome. Therefore, early diagnosis and appropriate intervention, including the identification of the underlying etiology, are important to effectively manage Pr-AKI. Therefore, we report a case of Pr-AKI after early miscarriage in a patient without hyperemesis gravidarum or septic abortion whose renal function gradually improved postoperatively for miscarriage.Case Presentation: A 34-year-old primigravid woman was referred to us for perinatal management at 6 weeks of gestation. Unfortunately, she was diagnosed with miscarriage 1 week later. The patient had no history of hyperemesis gravidarum or septic abortion; however, she developed oliguria, and her serum creatinine and blood urea nitrogen levels were abnormally increased. Consequently, she underwent a renal biopsy to evaluate renal dysfunction, which indicated tubulointerstitial damage. The patient also underwent manual vacuum aspiration for a miscarriage. Postoperatively, her urine output increased, and her renal function improved. She was determined to have experienced Pr-AKI due to her miscarriage.Conclusion: Our patient had Pr-AKI after a miscarriage in the absence of other causes. This case report highlights the presence of unknown causes of Pr-AKI, warranting further research for the development of preventive interventions.Keywords: pregnancy-related acute kidney injury, miscarriage, missed abortion, creatinine, renal insufficiency

To study the management and outcome of Pregnancy-related Acute Kidney Injury (PRAKI) in obstetrics. This observational and prospective study was conducted in 9270 deliveries including 79 cases of AKI in pregnancy at a tertiary medical college and hospital for the duration of one year. All pregnant and postpartum women attending out patient department (OPD) and emergency as booked and unbooked cases were included in our study. A detailed analysis of all investigations, management and outcome were recorded. Diagnostic criteria of AKI include (a) sudden in onset oliguria (24hrs urine output 1.5mg/dl. In the present study the creatinine values during admission or during diagnosis ranged between 1.5 to 18.2 mg/dl with a mean of 4.53±3.24 mg/dl. Majority (51.9%) of the patients have values less than 4 mg/dl. Out of 79 cases, 38 patients required hemodialysis that comes up to 48.1%. Most of the sepsis patients (17 out of 32) required hemodialysis. Case fatality rate due to AKI was 16.46% in our study. Sepsis was responsible for more maternal death, 15.6% in this study. Total 59 patients (74.68%) were discharged in stable conditions. [J Med Allied Sci. 2022; 12(2):43-46]

The study aimed to determine the causes, risk factors, and the outcomes of patients with postpartum acute kidney injury managed at Mogadishu Somali Turkey Training and Research Hospital, in Mogadishu, Somalia over a two years period.Methods: This study was conducted retrospectively at Mogadishu Somali-Turkey Training and Research Hospital, Somalia’s largest teaching and referral hospital. During a two-year period (January 2020 to December 2021), we evaluated women who had acute kidney injury during the postpartum period and were hospitalized in our hospital. The data was also evaluated for postpartum admission day and hospital stay. The requirement for dialysis and the results were documented. Maternal outcomes are categorized as follows: Complete recovery after discharge/follow-up, chronic dependence on hemodialysis and death during admission.Results: We studied 79 postpartum AKI patients. The mean age of the participants was 28.67 ± 6.14. Most patients (51%) were aged 20– 30, followed by 30– 40 (29%). According to self-reported comorbidities, most individuals had no history of chronic diseases, 8 (10.1%) had hypertension and 3 (3.8%) had heart failure, and DM and HTN 2(2.5%). The most common causes of PPAKI were eclampsia (24.1%), hemorrhagic shock, intrauterine mortality (16.5%), placenta abruptio and uterine rupture (8.9%). Hemorrhage (5.1%) and placenta previa (2.5%). The patient’s outcome was associated with age (p=0.04), platelet (p=0.024), and hospital stay (p=0.009).Conclusion: Postpartum acute kidney injury is very common in underdeveloped nations. Preeclampsia/Eclampsia, obstetric bleeding, and intrauterine death are the leading causes of postpartum acute kidney injury in Somalia. This tragic scenario may be avoided by providing appropriate antenatal care and raising awareness among Somali women about the benefits of antenatal care provided by public institutions.Keywords: postpartum AKI, pregnancy-related acute kidney injury, Somalia, eclampsia

Background: Pregnancy-related acute kidney injury (PRAKI) is an important cause of fetomaternal mortality and morbidity in developing countries. We undertook a systematic review to identify the causes of PRAKI among obstetric patients in India. Materials and methods: We systematically searched PubMed, MEDLINE, Embase, and Google Scholar using appropriate search terminology between 1 January 2010 to 31 December 2021. Studies reporting the etiology of PRAKI among obstetric patients (pregnant and within 42 days postpartum) in India were included for evaluation. Studies done in any other geographical location besides India were excluded. We also excluded studies done in any one trimester or any specific subgroup of patients [e.g., postpartum acute kidney injury (AKI), postabortal AKI]. A five-point questionnaire was used to assess the risk of bias in included studies. The results were synthesized as per preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Results: A total number of 7 studies with 477 participants were included for analysis. All were single-center descriptive observational studies either done in tertiary care public or private hospitals. Sepsis (mean, 41.9%; median, 49.4%; and range, 6-56.1%) was the most common cause of PRAKI followed by hemorrhage (mean, 22.1%; median, 23.5%; and range, 8.3-38.5%) and pregnancy-induced hypertension (mean, 20.9%; median, 20.7; and range, 11.5-39%). Among these seven studies, five were of moderate quality, one was of high quality, and another one was of low quality. Our study is limited due to the lack of consensus definition of PRAKI in literature and heterogeneity in reporting methods. Our study highlights the need for a structured reporting format for PRAKI to understand the true disease burden and take control measures. Conclusion: There is a moderate quality of evidence to suggest that sepsis followed by hemorrhage and pregnancy-induced hypertension are the commonest causes of PRAKI in India.

Objective: To evaluate factors associated with Pregnancy-related Kidney Injury (PRAKI) in women admitted to high dependency care unit at Women and Newborn Hospital in Lusaka, Zambia Methodology: This was an unmatched case-control study conducted in the high-dependency care unit at Women and Newborn Hospital in Lusaka. Study participants were recruited consecutively by convenience sampling. Participants' medical records were reviewed to capture serum creatinine levels; while a structured questionnaire was administered to eligible and consented study participants to capture data on sociodemographic, obstetric, and medical factors. Serum creatinine levels above 84µmol/l were used as criteria for classifying PRAKI. Excel was used for data cleaning and Stata v13 used for analysis. Descriptive statistics were done for all variables followed by univariate and multivariable logistic regression to determine association. 95% CI was used and p value of <0.05 was considered significant. Results: The study comprised of 185 study participants, split into 85 women with PRAKI (cases) and 100 women without PRAKI (controls). The median age was 29 years with 11years interquartile range. 75.3%of the study participants were in marriage relationships. Pre-existing hypertension was the most prevalent medical condition in both the cases (51.8%) and the controls (38%). Sickle cell disease was much less common at 1.2% in cases and 8% in controls. Among the obstetric conditions, preeclampsia was the most common condition at 77.6% and 60% in cases and controls respectively. Eclampsia was found in 38.8% of cases and 11% of controls. Sepsis was least common at 4.7% of cases. This study found that obstetricfactorssuch as eclampsia (AOR = 5.12, 95% CI [2.14 - 12.23]; p=0.0001), preeclampsia (AOR = 2.46, 95% CI [1.12 - 5.39]; p = 0.025), and postpartum haemorrhage were associated with the development of PRAKI. Medical conditions were not associated with PRAKI. Conclusion: Obstetric factors such aseclampsia, preeclampsia, andpost-partum haemorrhage were found to be significantly associated with the development of PRAKI among pregnant women studied.

Pregnancy‐related acute kidney injury (PRAKI) particularly on top of preeclampsia (PE) represents a major cause of maternal and fetal morbidity and mortality. Reliable diagnostic tools are needed to further evaluate the diagnosis and prognosis of PRAKI. Our objective was to study the diagnostic and prognostic value of angiogenic markers (e.g., stromal cell‐derived factor 1 (SDF‐1), vascular endothelial growth factor (VEGF), alarmins as uric acid) in women with PE and PRAKI. This prospective study included three groups; PRAKI, PE patients, and healthy controls that were compared regarding serum levels of the studied markers correlated to renal, maternal, and fetal outcomes. SDF‐1, VEGF, and uric acid levels were significantly different between the three included groups and predicted PRAKI diagnosis. Patients with hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome exhibited the highest titers of SDF‐1 and VEGF. A positive correlation was found between SDF‐1 and renal recovery. Conclusively, serum assays of SDF‐1, VEGF, and uric acid may add a diagnostic value in PRAKI and PE. [ABSTRACT FROM AUTHOR]

Introduction and objective: Pregnancy-related acute kidney injury (PRAKI) is one of the most important cause of maternal and fetal morbidity and mortality. Some of the reasons behind PRAKI may be due to sepsis, postpartum hemorrhage, preeclampsia, thrombotic microangiopathies (TMA), and acute fatty liver of pregnancy (AFLP). The timing of initiation of renal replacement therapy (RRT) for better patient outcome is still debatable. We conducted this study to establish whether earlier initiation of RRT in PRAKI improves fetomaternal survival compared to a more conservative approach. Materials and methods: This is a prospective study, where patients were screened at a multispecialty tertiary care hospital in north India for 1 year. The patients were divided into two groups: early RRT and standard AKI treatment. The demographic profile and clinical characteristics of the patients in terms of age, parity access to antenatal care, fetal outcome, urine output, hematological and biochemical profiles, RRT, duration of hospitalization, recovery of renal function, and patients survival were recorded. Results: This prospective study conducted included 13 patients in the early RRT group and 23 patients in the standard group. Considering the fetal outcome, the number of fetal deaths in early RRT group were 14.29%, whereas for the standard group it was 85.71%. In all, 75% of early RRT group and 25% of standard group had normal term delivery. Probability test applied showed they were statistically significant. One maternal mortality was there in the standard group. The indices of maternal outcome in PRAKI patients were found to be statistically insignificant. Conclusion: The planning of RRT whether early or late does not make a difference in maternal mortality or morbidity. The fetal outcome is significantly better for patients with early RRT than conservative treatment in PRAKI. [ABSTRACT FROM AUTHOR]

Objective: Despite being a Critical Intervention in the WHO Near-miss concept, the indications and clinical outcomes of patients with Pregnancy-Related Acute Kidney Injury (PRAKI) requiring dialysis at the Obafemi Awolowo University Teaching Hospitals Complex, Nigeria remain unknown. This retrospective review was conducted to facilitate counselling, prognostication and introduction of preventative measures by providing contemporary data on the aetiology and clinical outcomes of women with PRAKI.Study Design: A retrospective review. The indications for dialysis and feto-maternal outcomes of women with PRAKI requiring dialysis between January 2007 and December 2016 were reviewed. Analysis was performed with IBM SPSS 21.0.Results: There were 43 patients with PRAKI that required dialysis and 11,242 live births, with Maternal Near Miss Ratio (MNMR) of 3.8/1000 live births. Preeclampsia/ecclampsia (40%), Sepsis (37.5%) and Haemorrhage (20%) were the leading aetiologies of kidney injury, while oligo-anuria (100%) was the commonest clinical presentation. Majority (78%) of them had ≤four dialysis sessions before recovery of renal function. The mean (±SD) gestational age and birth weight at delivery were 36 (±3.1) weeks and 2.9 (±0.6)kg, while the Maternal Mortality Index and Perinatal mortality rates were 18% and 34% respectively. Delayed referral, and lower number of dialysis sessions were the significant predictors of mortality, while four women discontinued care due to cost.Conclusion: The high rate of Pregnancy-related acute kidney injury requiring dialysis, with its attendant morbidity and mortality are largely preventable. The prognosis is however good with standardised care. Functional emergency obstetric services, and a review of the Nigerian healthcare financing system are advocated. [ABSTRACT FROM AUTHOR]

Objective: To describe the clinical profile and outcomes of women with pregnancy-related acute kidney injury (AKI) undergoing dialysis at Saint Paul's Hospital Millennium Medical College, Addis Ababa, where the first publicly funded large-scale dialysis service in Ethiopia was established.Methods: In a hospital-based retrospective study, clinical records were reviewed for all women with pregnancy-related AKI attending the hemodialysis unit at the study center between August 2013 and July 2015.Results: In total, 42 pregnant women with pregnancy-related AKI underwent dialysis. Their mean age was 28.9 ± 5.9 years. The most common cause of pregnancy-related AKI was pre-eclampsia or eclampsia (31/42, 74%), followed by puerperal sepsis (6/42, 14%). The mean number of dialysis sessions was 4.8 ± 4.6; the most common indication for dialysis was refractory fluid overload (35/42, 83%). Overall, 35 (83%) women were discharged with improvement, 5 (12%) died, and 2 (5%) absconded. Of the five maternal deaths, three women had pre-eclampsia-related AKI and two had puerperal sepsis-related AKI.Conclusion: Hypertensive disorders of pregnancy were the leading cause of pregnancy-related AKI, which can be easily prevented with early diagnosis and timely intervention. Improving the quality of prenatal care to recognize hypertensive disorders during pregnancy, coupled with prompt management, might help to reduce maternal morbidity and mortality related to AKI.

Pregnancy-related acute kidney injury (PRAKI) contributes to 3-7% of overall acute kidney injury (AKI) cases in Indian subcontinent. The aim ofthis study was to determine the outcomes of PRAKI and riskfactors associated with renal injury and maternal mortality. One hundred and sixty-five patients with PRAKI, seen at M. S. Ramaiah Medical College between 2005 and 2014, were included in this, observational study. AKI was analyzed in terms of maximal stage of renal injury attained as per Risk, Injury, Failure, Loss of function, and End-stage renal disease (RIFLE) criteria. Outcomes included requirement for renal replacement therapy (RRT), maternal, and fetal mortality. Incidence of PRAKI was 1.56%, and the mean age of the study population was 25 years. Fifty percent of the patients were diagnosed with PRAKI during their first pregnancy. PRAKI was observed most commonly in the postpartum period (60%), followed by third trimester (32%); as per RIFLE criteria, failure was seen in 36% and injury in 34%. Thirty percent of cases required RRT. Sepsis (59%), pre-eclampsia, and eclampsia (56%) were the leading causes of PRAKI, while sepsis was the leading cause of maternal mortality. Maternal and fetal mortality were 20% and 22%, respectively. In univariate analysis, shock, hemorrhage requiring transfusion of >5 units packed red blood cells, oliguria, and "Loss" category of RIFLE were significantly associated with mortality. Majority of the patients (57%) required Intensive Care Unit care with a mean duration of admission at 7.3 days, and 75% was diagnosed with AKI at the time of admission. We report the lowest incidence of PRAKI in contemporary Indian literature. PRAKI was associated with high maternal and fetal mortality, with sepsis being the leading cause. No association was noted between mortality and initial stages of RIFLE criteria. [ABSTRACT FROM AUTHOR]

Postpartum acute kidney injury (PPAKI) constitutes an important cause of obstetric AKI. It is associated with high maternal and fetal mortality in developing nations. The aim of this study is to survey the etiology and outcomes of PPAKI in a tertiary care Indian hospital. Ninety-nine patients, without prior comorbidities, treated for PPAKI, between 2005–2014 at M.S. Ramaiah Medical College, were included for analysis in this retrospective, observational study. AKI was analyzed in terms of maximal stage of renal injury attained as per RIFLE criteria. Outcomes included requirement for renal replacement therapy (RRT), maternal and fetal outcomes. PPAKI constituted 60% of all obstetric AKI cases. Median maternal age was 23 years and 52% of patients were primigravidas. Mean serum creatinine was 4.1 mg/dL. Failure (33%) and injury (31%) were the major categories as per RIFLE criteria. Thirty-nine percent of cases required RRT. Sepsis, particularly puerperal sepsis, was the leading causes of PPAKI (75% of cases) and maternal mortality (94% of deaths). Maternal and fetal mortality were 19% and 22% respectively. The incidence of cortical necrosis was 10.3%. Three patients required long-term RRT. In conclusion, consistent with other Indian literature, we report a high incidence of PPAKI. We found incremental mortality on moving from “Risk” to “Failure” category of RIFLE. PPAKI was associated with high maternal and fetal mortality with sepsis being the leading cause. Our study highlights the need for provision of better quality of maternal care and fetal monitoring to decrease mortality associated with PPAKI in developing countries. [ABSTRACT FROM PUBLISHER]

Background: Acute kidney injury (AKI) is a serious complication in pregnancy, resulting in significant maternal and fetal morbidity/mortality. The aim of this study was to evaluate the magnitude of pregnancy-related AKI (PRAKI) in a North Indian population, and its contributing factors., Materials and Methods: This prospective study was carried out at the department of obstetrics and gynecology in collaboration with the nephrology unit and internal medicine department at King George Medical University from June 2019 to October 2020. After informed consent and ethical clearance, a total of 150 PRAKI women were enrolled, and 98 women were subjected to renal replacement therapy as per Kidney Disease Improving Global Outcomes 2012 guideline and were followed for 3 months for renal and fetomaternal outcome., Results: There was a high incidence (1.02%) of AKI during pregnancy and puerperium. Majority (57.3%) of the women were aged 26-30 years, and 93.3% had institutional deliveries. About 49% of the women suffering from PRAKI were multipara, and most were identified in the postpartum period (82%). Hypertensive disorder of pregnancy (48%), puerperal sepsis (45%), and hemorrhage (34%) were the associated causes for PRAKI. Stillbirth/intrauterine death (IUD) was higher in Stage II (53.8%) and Stage III AKI (37.7%) (none in Stage I AKI). The majority of the neonates were born with a birth weight of ≤2500 g irrespective of the stages of AKI. Preterm deliveries were significantly higher in Stage II AKI (53.8%) than in Stage I (33.3%) and Stage III (20.0%). Thirty-seven cases of PRAKI were managed conservatively, while 98 required dialysis. Complete recovery occurred in 27.3% and partial renal recovery in 31.3%. However, 3.3% progressed to chronic kidney disease, 34% expired, and 4% were lost to follow-up. High maternal mortality of 30.1% was observed in those dialyzed., Conclusion: AKI is associated with fetal growth restriction and preterm deliveries. Stillbirth/IUD is higher in Stage II and Stage III AKI., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Family and Community Medicine.)

Recent trials have failed to show a survival beneft from the early initiation of dialytic therapies in acute kidney injury (AKI), but the problem has not been studied in pregnancy-related AKI. While the KDIGO criteria have not been validated in pregnancy-related acute kidney injury (PRAKI), additionally both fetal and maternal outcomes require to be studied. The short observational study by Banerjee et al. contains some interesting observations. [ABSTRACT FROM AUTHOR]

Objective: This study was performed to determine the association of D-dimers measured at the time of admission with the development of acute kidney injury (AKI) in pregnant women., Methods: We retrospectively analyzed the data of 625 women who developed AKI and 628 normal pregnant women admitted to our hospital from January 2014 to December 2018. The primary endpoint of the study was the development of AKI in pregnant women, and the secondary endpoint was the development of dialysis and death in women with AKI. Univariate and multivariate analyses were conducted., Results: The D-dimer concentration was significantly higher in patients with than without pregnancy-related AKI (PR-AKI). Multivariate logistic regression showed that a D-dimer concentration of >1108 ng/mL was an independent predictor of PR-AKI. The area under the curve of the D-dimer concentration as a prognostic indicator of PR-AKI was 0.652 (95% confidence interval, 0.622-0.683), that for patients with PR-AKI undergoing dialysis was 0.819 (95% confidence interval, 0.709-0.928), and that for patients who died was 0.828 (95% confidence interval, 0.670-0.986)., Conclusion: The D-dimer concentration is significantly associated with the development of AKI in pregnant patients and may increase the risk of dialysis and death in women with AKI.

Objectives: Hypertension is a serious complication of pregnancy-related acute kidney injury (PR-AKI). This study aimed to determine the effect of hypertension on the prognosis of PR-AKI, maternal outcomes, and fetal outcome., Methods: Patients with PR-AKI in a hospital from January 2008 to June 2018 were enrolled for this study. Patients with or without hypertension were grouped by 1꞉1 propensity matching score. The effect of hypertension on the prognosis of PR-AKI was evaluated by multivariate Cox regression before and after matching., Results: Of the 30 680 women who attended the Department of Obstetrics, 126 patients were diagnosed as PR-AKI, the incidence was 0.41%. The age was (29.04±2.32) years. There were 50 cases in the hypertension group, accounting for 39.68%. Using the propensity score method, 48 pairs of patients were successfully matched, and the covariates between the two groups were balanced. After matching and adjusting for relevant clinical factors, Cox regression analysis showed that risk of end-stage renal disease (ESRD) was increased in the hypertension group compared with the normal blood pressure group (HR=2.951, 95％ CI 1.067 to 8.275, P =0.034). The risk of risk of adverse maternal outcome was increased (HR=2.815, 95% CI 1.271 to 6.233, P =0.009), and the risk of fetal adverse outcome was increased (HR=1.437, 95% CI 1.028 to 4.623, P =0.021)., Conclusions: Hypertension is an independent risk factor for ESRD, adverse maternal outcomes, and adverse fetal outcomes in the PR-AKI patients.

Pregnancy-related acute kidney injury (PR-AKI) is a heterogeneous disorder with multiple aetiologies that can occur at any time throughout pregnancy and the post-partum period. PR-AKI is an important obstetric complication that is associated with significant maternal and foetal morbidity and mortality. Although there has been an overall decline in the incidence of PR-AKI worldwide, a recent shift in the occurrence of this disease has been reported. Following improvements in obstetric care, PR-AKI incidence has been reduced in developing countries, whereas an increase in PR-AKI incidence has been reported in developed countries. Awareness of the physiological adaptations of the renal system is essential for the diagnosis and management of kidney impairment in pregnancy. In this review we scrutinize the factors that have contributed to the changing epidemiology of PR-AKI and discuss challenges in the diagnosis and management of acute kidney injury (AKI) in pregnancy from an obstetrics perspective. Thereafter we provide brief discussions on the diagnostic approach of certain PR-AKI aetiologies and summarize key therapeutic measures. [ABSTRACT FROM AUTHOR]

Acute kidney injury (AKI) is a complex disorder that occurs in several clinical settings. During pregnancy, there are additional unique conditions that contribute to AKI. The clinical manifestations of AKI during pregnancy range from a minimal elevation in serum creatinine to renal failure requiring renal replacement therapy, similar to AKI in the general population. Recent epidemiologic studies in the general population show an increase in mortality associated with AKI, particularly when dialysis is required. The incidence of AKI in pregnancy remains a cause of significant morbidity and mortality., (Copyright © 2016 Elsevier Inc. All rights reserved.)
