Abstract
OBJECTIVE To observe the impact of acute renal morbidities with obstetrical emergencies on maternal health. METHODS In this study pregnant women between 28-40 weeks gestational period and delivered women in their puerperal period up to 42 days after delivery having acute renal problems associated with obstetrical emergencies were included. Pregnant and delivered women with obstetrical emergencies and associated other morbidities were excluded. These women were registered on the predesigned proforma after taking written informed consent and taking approval from institutional ethic research committee. The data was collected and analyzed on SPSS version 21. RESULT Out of these 196 total registered women, majority of these women 81(41.32%) were between 21-30 years of age and multiparous women with parity four and above were 83(42.34%). Commonest presenting symptoms were generalized oedema 123(62.75%) and oligouria 92(46.93%). Frequent obstetrical emergencies observed were pre-eclampsia 53(27.04%), post partum haemorrhage 48(24.48%) and ante partum haemorrhage 36(18.36%) women. The complete recovery was observed in 86(43.87%) women, while mortality was seen in 56(28.57%) women. CONCLUSION Renal morbidities were more frequently observed in obstetrical emergencies leading to high morbidity and mortality rate.

Abstract
OBJECTIVE To examine whether changes in postpartum haemorrhage, hypertensive disorders of pregnancy, or other risk factors explain the increase in obstetric acute renal failure in Canada. DESIGN Retrospective cohort study. SETTING Canada (excluding the province of Quebec). PARTICIPANTS All hospital deliveries from 2003 to 2010 (n=2,193,425). MAIN OUTCOME MEASURES Obstetric acute renal failure identified by ICD-10 diagnostic codes. METHODS Information on all hospital deliveries in Canada (excluding Quebec) between 2003 and 2010 (n=2,193,425) was obtained from the Canadian Institute for Health Information. Temporal trends in obstetric acute renal failure were assessed among women with and without postpartum haemorrhage, hypertensive disorders of pregnancy, or other risk factors. Logistic regression was used to determine if changes in risk factors explained the temporal increase in obstetric acute renal failure. RESULTS Rates of obstetric acute renal failure rose from 1.66 to 2.68 per 10,000 deliveries between 2003-04 and 2009-10 (61% increase, 95% confidence interval 24% to 110%). Adjustment for postpartum haemorrhage, hypertensive disorders, and other factors did not attenuate the increase. The temporal increase in acute renal failure was restricted to deliveries with hypertensive disorders (adjusted increase 95%, 95% confidence interval 38% to 176%), and was especially pronounced among women with gestational hypertension with significant proteinuria (adjusted increase 171%, 71% to 329%). No significant increase occurred among women without hypertensive disorders (adjusted increase 12%, -28 to 72%). CONCLUSIONS The increase in obstetric acute renal failure in Canada between 2003 and 2010 was restricted to women with hypertensive disorders and was especially pronounced among women with pre-eclampsia. Further study is required to determine the cause of the increase among women with pre-eclampsia.

Abstract
PURPOSE To investigate the characteristics of women who have kidney injury during pregnancy. METHODS Medical records of all women who gave birth at our institution between January 1, 2005, and December 31, 2010, were retrospectively reviewed electronically. We identified those who incurred a kidney injury [defined by modified Acute Kidney Injury Network (AKIN) criteria: serum creatinine (sCr) increase ≥0.3 mg/dL] during pregnancy or within 30 days postpartum. Identified case records were reviewed in detail. RESULTS During the study period, 54 women had a kidney injury (0.4 % estimated incidence) with a mean (SD) increase in sCr of 0.46 (0.29) mg/dL; most injuries were AKIN stage 1 with transient increases in sCr. Most of the women (n = 48, 87.3 %) had substantial preexisting or pregnancy-associated comorbid conditions (e.g., kidney disease, hypertension, diabetes), complications (e.g., preeclampsia, HELLP syndrome), or a complicated obstetric course (hemorrhage, infections) that could have contributed to the development of a kidney injury. Two patients had AKIN stage 3 injuries: a previously healthy patient who had a massive hemorrhage during cesarean delivery, and a patient with a renal transplant who had deterioration and eventual postpartum failure of her transplanted kidney. CONCLUSIONS The majority of pregnancy-associated kidney injuries were transient and occurred in women with substantial comorbid conditions or complicated pregnancies.

Abstract
Acute renal failure (ARF) requiring hemodialysis is a rare complication of pregnancy in western world, but in developing countries, it is still frequent. The objective of this study was to determine the epidemiology, etiologies, clinical data and outcomes for pregnant women with ARF requiring dialysis. We studied the records of 58 patients with ARF who had needed dialysis in the obstetric intensive care unit of the maternity teaching hospital of Ibn Rochd (Casablanca) between January 1st 2002 and 31st December 2008. Anterior renal diseases and post-renal causes were excluded. Epidemiological, clinical, biological data were recorded, the outcome of patients were studied 1 and 3 months after discharge from hospital. The incidence of ARF in our unit was 9.87 per 10,000 pregnancies; and constitutes 2.49% of all admissions in the obstetric ICU. The mean age and parity were respectively 28±7 years and 2.82. Main aetiology was preeclampsia-eclampsia (39 cases: 67.2%), haemorrhage (15 cases: 25.9%), sepsis (five cases: 8.6%), fetal death, (two cases: 3.6%) and acute fatty liver (one patient: 1.8%). Often, several causes were associated. In one case, we found no evident cause despite radiological imaging and histological exam. Recovery is faster in pre-eclampsia than others causes. The outcomes included renal recovery in 42 cases (72.4%), chronic renal failure in four cases (6.9%). Mortality rate was 13.8% (eight deaths). Preventive and early management of obstetrical complications could improve pregnancy-associated ARF.

Abstract
OBJECTIVE To determine the relationship between long-term mortality and acute kidney injury (AKI) during hospitalization after major surgery. SUMMARY BACKGROUND DATA AKI is associated with a risk of short-term mortality that is proportional to its severity; however the long-term survival of patients with AKI is poorly studied. METHODS This is a retrospective cohort study of 10,518 patients with no history of chronic kidney disease who were discharged after a major surgery between 1992 and 2002. AKI was defined by the RIFLE (Risk, Injury, Failure, Loss, and End-stage Kidney) classification, which requires at least a 50% increase in serum creatinine (sCr) and stratifies patients into 3 severity stages: risk, injury, and failure. Patient survival was determined through the National Social Security Death Index. Long-term survival was analyzed using a risk-adjusted Cox proportional hazards regression model. RESULTS In the risk-adjusted model, survival was worse among patients with AKI and was proportional to its severity with an adjusted hazard ratio of 1.18 (95% confidence interval [CI], 1.08-1.29) for the RIFLE-Risk class and 1.57 (95% CI, 1.40-1.75) for the RIFLE-Failure class, compared with patients without AKI (P < 0.001). Patients with complete renal recovery after AKI still had an increased adjusted hazard ratio for death of 1.20 (95% CI, 1.10-1.31) compared with patients without AKI (P < 0.001). CONCLUSIONS In a large single-center cohort of patients discharged after major surgery, AKI with even small changes in sCr level during hospitalization was associated with an independent long-term risk of death.

Abstract
BACKGROUND Acute kidney injury (AKI) is common in hospitalized patients. The impact of AKI on long-term outcomes is controversial. STUDY DESIGN Systematic review and meta-analysis. SETTING & PARTICIPANTS Persons with AKI. SELECTION CRITERIA FOR STUDIES MEDLINE and EMBASE databases were searched from 1985 through October 2007. Original studies describing outcomes of AKI for patients who survived hospital discharge were included. Studies were excluded from review when participants were followed up for less than 6 months. PREDICTOR AKI, defined as acute changes in serum creatinine level or acute need for renal replacement therapy. OUTCOMES Chronic kidney disease (CKD), cardiovascular disease, and mortality. RESULTS 48 studies that contained a total of 47,017 participants were reviewed; 15 studies reported long-term data for patients without AKI. The incidence rate of mortality was 8.9 deaths/100 person-years in survivors of AKI and 4.3 deaths/100 patient-years in survivors without AKI (rate ratio [RR], 2.59; 95% confidence interval, 1.97 to 3.42). AKI was associated independently with mortality risk in 6 of 6 studies that performed multivariate adjustment (adjusted RR, 1.6 to 3.9) and with myocardial infarction in 2 of 2 studies (RR, 2.05; 95% confidence interval, 1.61 to 2.61). The incidence rate of CKD after an episode of AKI was 7.8 events/100 patient-years, and the rate of end-stage renal disease was 4.9 events/100 patient-years. LIMITATIONS The relative risk for CKD and end-stage renal disease after AKI was unattainable because of lack of follow-up of appropriate controls without AKI. CONCLUSIONS The development of AKI, defined as acute changes in serum creatinine level, characterizes hospitalized patients at increased risk of long-term adverse outcomes.

Abstract
Acute kidney injury (AKI) is common in the intensive care unit and is associated with significant morbidity and mortality. Based on the RIFLE criteria, AKI occurs in up to 67% of patients in the intensive care unit (ICU), with approximately 4% of critically ill patients requiring renal replacement therapy (RRT). It is well known that this subset of AKI patients who require RRT have an in-hospital mortality rate exceeding 50%. However, long-term outcomes of survivors of AKI requiring RRT remain poorly described. Long-term mortality is greater in those patients who survived AKI when compared with critically ill patients without AKI. Long-term morbidity, renal and extrarenal, is a frequent and underappreciated complication of AKI. Among survivors of AKI at long-term follow-up (1-10 years), approximately 12.5% are dialysis dependent (wide range of 1%-64%, depending on the patient population) and 19% to 31% have chronic kidney disease. According to the United States Renal Data System, "acute tubular necrosis without recovery" as a cause of end-stage kidney disease increased from 1.2% in 1994 to 1998 to 1.7% in 1999 to 2003. The incidence will likely continue to rise with the aging population, increase in comorbidities, and expansion of intensive care unit capabilities. AKI is an underrecognized cause of chronic kidney disease (CKD) and patients who survive should be followed closely for new CKD and/or progression of underlying CKD.

Abstract
As long-term outcome studies of acute renal failure (ARF) are scarce and non-homogeneous, we studied 187 consecutive acute tubular necrosis (ATN) patients without previous nephropathies, discharged alive from our hospital between October 77 and December 92 and followed-up until December 99 (range 7-22 years; median 7.2). Variables were analyzed at the time of the acute episode and during follow-up. In 2000-2001 a clinical evaluation was made in 58 of the 82 patients still alive. Ten patients were lost to follow-up and 95 died. In 59% death was related with the disease present when the ATN developed. Kaplan-Meir survival curve showed 89, 67, 50, and 40% at 1, 5, 10, and 15 years, respectively, after discharge. Survival curves were significantly better (log-rank P<0.001) among the youngest, those surviving a polytrauma, those without comorbidity and surprisingly those treated in intensive care units. The proportional Cox model showed that age (hazard ratio (HR) 1.04 per year of age; P=0.000), presence of comorbid factors (HR 4.29; P=0.006), surgical admission (HR 0.45; P=0.000), and male sex (HR 1.72; P=0.020) were the variables associated with long-term follow-up. In the evaluated patients renal function was normal in 81%. Long-term outcome after ARF depends on absence of co-morbid factors, cause of initial admission and age. Although the late mortality rate is high and related with the original disease, renal function is adequate in most patients.

Abstract
OBJECTIVES To provide an evidence-based, up-to-date review of the literature regarding the assessment and management of acute renal failure that may affect women during pregnancy and the postpartum period. DESIGN A review of the current literature was performed. RESULTS Acute renal failure is a rare complication of pregnancy but is associated with significant morbidity and mortality. Management requires knowledge of the renal physiologic changes occurring in pregnancy and the relevant diagnoses, both pregnancy-specific and those that may coincidentally occur with pregnancy. In addition, fetal effects must be taken into consideration. CONCLUSIONS Ideal care for women with acute renal failure in pregnancy or postpartum requires a multidisciplinary approach that may include maternal-fetal medicine, critical care medicine, nephrology, and neonatology specialists.

Abstract
Acute renal failure (ARF) is a cause of high morbidity and mortality associated with long hospital stay, and expensive treatment. The initial approach to patients with ARF should be focused on preventing future injury to the kidney. Two hundred eighty-three ARF patients, treated from January 1996 to June 2002, were retrospectively investigated for their etiology, clinic features, and laboratory characteristics, as well as treatment results and mortality rate. The mean age was 52.3 +/- 18.7 years. Patients with hospital-acquired ARF comprised 38.8% of the sample. Renal causes (60%) were responsible for most ARF patients. They were medical (63.95%), surgical (23.67%), and obstetric (12.4%) causes. Twenty-five percent of patients with ARF had multiple etiologies. Hemolysis elevated liver enzymes low platelets (HELLP) syndrome was seen in the most of the obstetric-related ARF cases. Signs of hypervolemia were present in approximately 50% of the cases. Oliguric patients comprised 59.7% of the sample, and the mean time to oliguria was 5.2 +/- 4.1 days. The necessity of dialysis was greater in oliguric patients (42.6%) and the ratio of complete/partial improvement (82.2%) was greater among non-oligoanuric patients. However, there was no significant difference between mortality rates. Irreversible renal insufficiency did not develop in the non-oliguric cases. Also, 7.4% of ARF patients died, with the main causes being infection (31.8%) and cardiovascular events (27.2%). Medical problems are important in the etiology of ARF as well as obstetric cases. The mortality rate was low in our cases, a situation that may be explained by medical causes being of importance in the etiology. We are of the opinion that early referral of patients to a nephrologist and following treatment in the nephrology clinic may positively affect the outcome.

Abstract
HELLP syndrome, a syndrome of hemolysis, elevated liver enzymes and low platelets may occur in pregnancy with pre-eclampsia/eclampsia, and its a significant complication is acute renal failure (ARF). The aim of study was to determine frequency and outcome of HELLP syndrome complicated by ARF. Thirty-nine patients with pregnancy-related ARF were treated between Jan 1, 1989 and Jan 1, 1999. In these patients, the most frequent causes were HELLP syndrome (n = 14; 36%), postpartum hemorrhage (n = 10; 26%), pre-eclampsia/eclampsia (n = 6; 15%) and abruptio placenta (n = 4; 10%). Seven of the patients with HELLP syndrome had impairment of consciousness during hospitalization. Of these patients, coma in 5, stupor in 1, confusion in 1 were diagnosed. Twelve of the patients with HELLP syndrome and 14 of the other patients were treated by dialysis. Mann-Whitney U test and chi2 test(corrected by Yates and Fisher exact) were used for statistical analysis. Although serious clinical findings, with supportive treatment, 12 patients with HELLP syndrome and 21 other patients were fully recovered. One patient both with and without HELLP syndrome could not recovered due to diffuse cortical necrosis. Moreover, one patient with HELLP syndrome and 3 other patients were died. Mortality rate of the patients with HELLP syndrome was not found different from those of the other patients (p = 0.544). The causes of death were cerebral hemorrhage in patient with HELLP syndrome and disseminated intravascular coagulation (n = 1), cerebral emboli (n = 1), adult respiratory distress syndrome (n = 1). Fetal death occurred in 4 patients with HELLP syndrome (28.5%) and 7 other patients (28%), and rates were similar (p > 0.5). Finally, HELLP syndrome was the most frequent cause leading to ARF in pregnancy and their prognosis was not different from those of the other patients.

Abstract
BACKGROUND The aetiological spectrum of acute renal failure (ARF) has changed in developed countries. It was the purpose of the study to evaluate whether similar changes have occurred in this part of the world as well. METHODS In a prospective study a total of 439 patients with ARF were evaluated. They had been admitted to one hospital during two successive periods, i.e. 1983-1990 and 1991-1997. RESULTS Of 439 patients with ARF, 116 were admitted in 1983-1990 (first period) and 323 in 1991-1997 (second period). The age of presentation increased from 49.8+/-6.2 years in the first period to 58.8+/-16.4 years in the second. Medical causes were present in 259 cases (59%), surgical causes in 110 cases (25%), and obstetric causes in 70 cases (16%). The frequency of surgical cases decreased from 28.4% in the first period to 23.8% in the second period. The respective figures for obstetric cases were 18.9% and 14.8%. Mortality did not change with time (33.6% in the first and 31.0% in the second period); the overall mortality was 31.7%. The mortality was higher for surgical (45.5%) than for obstetric (27.8%) and medical ARF (24.3%). CONCLUSION In the mid-1970s, the most common causes of ARF in Turkey were obstetric complications and septic abortion. The aetiological spectrum of ARF has changed and today medical causes predominate. ARF resulting from septic abortion has become rare, possibly because of liberalization of abortion in 1983 in Turkey.

Abstract
In recent years, the incidence of acute renal failure (ARF) in pregnancy has decreased in developed countries. This cause of this decline has been reported to be liberalized abortion laws and improved prenatal care. The aim of this study was to determine if the incidence and etiology of ARE in pregnancy in our population had undergone similar changes. Between January 1, 1980 and January 1 1997 the number of the patients with ARF was 487. In 74 (15%) of these patients, the etiology of ARF was associated with pregnancy. The frequency of ARF in pregnancy was 17.4% between January 1980 and August 1985, 15.4% between September 1985 and November 1989, 13.5% between December 1989 and January 1997. The differences between the frequencies were not statistically significant (p > 0.5). In the present series, the various disorders leading to ARF in pregnancy were abortion (30%), HELP syndrome and pre-eclampsia (14%), pre-eclampsia or eclampsia (12%), postpartum hemorrhage (15%), fetal death (12%), abruption placentae (6%) and placentae previa (1%).

Abstract
Acute renal failure (ARF) has become a very rare complication of pregnancy. This results from the virtual disappearance of septic abortion ARF and from the improvement of prenatal care, including the prevention of volume contraction which is mainly due to uterine haemorrhage, early diagnosis, and treatment of other classic maternal complications such as pre-eclampsia and acute pyelonephritis. The incidence of bilateral renal cortical necrosis has also been declining during the last decade. Acute fatty liver, a potentially fatal disease, is often complicated by ARF. Early recognition of this disorder, with prompt termination of pregnancy and intensive supportive therapy, can reduce fetal and maternal mortality rate. The syndrome of idiopathic postpartum renal failure is also associated with a high morbidity and mortality. Beyond supportive treatment, including haemodialysis or peritoneal dialysis and the use of potent antihypertensive drugs to control blood pressure and blood transfusion if necessary, specific therapy as plasma infusion, plasma exchange and antiplatelet drugs may be of value. Both peritoneal dialysis and haemodialysis may be used in gravidas with ARF. Early 'prophylactic' dialysis should be applied to pregnant women. Careful monitoring of fluid balance and anticoagulation is necessary during dialysis.
