Until recently, no uniform standard existed for diagnosing and classifying acute renal failure. To clarify diagnosis, the Acute Dialysis Quality Initiative group stated its consensus on the need for a clear definition and classification system of renal dysfunction with measurable criteria. Today the term acute kidney injury has replaced the term acute renal failure, with an understanding that such injury is a common clinical problem in critically ill patients and typically is predictive of an increase in morbidity and mortality. A classification system, known as RIFLE (risk of injury, injury, failure, loss of function, and end-stage renal failure), includes specific goals for preventing acute kidney injury: adequate hydration, maintenance of renal perfusion, limiting exposure to nephrotoxins, drug protective strategies, and the use of renal replacement therapies that reduce renal injury.

Acute Renal Failure is most challenging clinical problem when it occurs during pregnancy. Septic abortion is the most common cause of PRAKI in developing countries but its worldwide incidence has declined significantly. Sometimes septic abortion complicated by multiorgan failure. This 35 yrs multiparous lady having history of induced abortion, presented with multiorgan dysfunction. The patient was successfully treated and discharged with total care.Journal of Current and Advance Medical Research, 2015;2(2):47-48

Common Cause

Introduction: In the elderly, impairment of kidney function occurs. Renal diseases overlap with anatomic and functional changes related to age-related involutionary processes. Mortality among patients with acute renal injury is approximately 50%, despite advances in treatment and diagnosis of AKI. The aim: To assess the incidence of acute kidney injury in elderly patients and to analyze the causes of acute renal failure depending on age. Materials and methods: A retrospective analysis included medical documentation of patients hospitalized in the Nephrology Clinic during the 6-month period. During this period 452 patients were hospitalized in the clinic. A group of 77 patients with acute renal failure as a reason for hospitalization was included in the study. Results: The prerenal form was the most common cause of AKI in both age groups. In both age groups, the most common cause was dehydration; in the group of patients up to 65 years of age, dehydration was 29.17%; in the group of people over 65 years - 43.39%. Renal replacement therapy in patients with AKI was used in 14.29% of patients. In the group of patients up to 65 years of age hemodialysis was 16.67% and above 65 years of age. -13.21% of patients. The average creatinine level in the group of younger patients at admission was 5.16 ± 3.71 mg / dl, in the group of older patients 3.14 ± 1.63 mg / dl. The size of glomerular filtration GFR in the group of younger patients at admission was 21.14 ± 19.54 ml / min, in the group of older patients 23.34 ± 13.33 ml / min. Conclusions: The main cause of acute kidney injury regardless of the age group was dehydration. Due to the high percentage of AKI in the elderly, this group requires more preventive action, not only in the hospital but also at home.

Acute renal failure definitions have changed dramatically over the last 5 to 10 years as a result of criteria established through the following consensus statements/organizations: RIFLE (Risk, Injury, Failure, Loss of function, End stage renal disease), AKIN (Acute Kidney Injury Network), and KDIGO (Kidney Disease: Improving Global Outcomes). In 2002, the Acute Dialysis Quality Initiative was tasked with the goal of establishing a consensus statement for acute kidney injury (AKI). The first order of business was to provide a standard definition of AKI. Up to this point, literature comparison was challenging as studies lacked uniformity in renal injury definitions. Implementing results into evidence-based clinical practice was difficult. The panel coined the term “acute kidney injury,” encompassing previous terms, such as renal failure and acute tubular necrosis. This new terminology represented a broad range of renal insults, from dehydration to those requiring renal replacement therapy (RRT). This review provides an algorithmic approach to the epidemiology, pathophysiology, diagnosis, prevention, and management of AKI. Also discussed are special circumstances, including rhabdomyolysis, contrast-induced nephropathy, and hepatorenal syndrome. Tables outline the AKIN criteria, most current KDIGO consensus guidelines for definition of AKI, differential diagnosis of AKI, agents capable of causing AKI, treatment for specific complications associated with AKI, and options for continuous RRT. Figures show the RIFLE classification scheme and KDIGO staging with prevention strategies. This review contains 1 management algorithm, 2 figures, 6 tables, and 85 references.

Rapid Decrease

Acute renal failure (also referred to as acute kidney injury) refers to a rapid decrease in renal function; it is reflected by an increase in blood urea and creatinine and is often associated with oliguria (a urine volume of less than 400 ml/24 hours). It usually develops over days to weeks. Acute kidney injury has been variously classified, but the current classifications are based on the glomerular filtration rate (or creatinine), looking at changes from baseline, and the presence of oliguria or anuria. The potential etiologies of acute kidney injury are usually considered anatomically under the headings prerenal, renal (intrinsic), and postrenal. This chapter looks at the etiology, symptoms, clinical features, demographics, complications, diagnosis, and treatment of acute kidney injury.
