PURPOSE Among kidney transplant recipients with acute kidney injury, the differential diagnosis must be broadened to include conditions such as rejection, immunocompromised host infections, anatomic pathologies, and recurrent or de novo glomerular diseases. In this case report, we describe an unusual cause of acute renal allograft injury due to external compression of the allograft ureter. ME...

Renal ischemia produces renal sympathoexcitation that is responsible for the development of ischemic acute kidney injury. The present study examined changes in the sympathetic nerve function in mice. Ischemic acute kidney injury was induced by occlusion of both renal pedicles. Renal ischemia/reperfusion increased blood urea nitrogen and plasma creatinine and expression of tyrosine hydroxylase, ...

BACKGROUND Acute tubular necrosis and pigment induced kidney injury are well described consequences of cocaine abuse. However, acute interstitial nephritis associated with cocaine use has been previously reported in only three patients. CASE PRESENTATION We present the case of a 49-year-old man who developed acute kidney injury from biopsy-proven interstitial nephritis after nasal insufflatio...

STUDY OBJECTIVE The study objective was to determine whether intravenous contrast administration for computed tomography (CT) is independently associated with increased risk for acute kidney injury and adverse clinical outcomes. METHODS This single-center retrospective cohort analysis was performed in a large, urban, academic emergency department with an average census of 62,179 visits per ye...

CLASSIC ANIMAL MODELS of critical illness have focused on injury of a single end-organ, with the goal of better understanding and attenuating that injury, and ultimately developing novel disease-focused therapies. For example, acute lung injury (ALI) can be induced in animal models by administration of endotoxin or hydrochloric acid, exposure to hyperoxic conditions, and the use of injurious, h...

Acute kidney injury (AKI) represents a medical emergency associated with poor clinical outcomes. The international guideline group Kidney Disease: Improving Global Outcomes (KDIGO) has defined AKI according to rises in serum creatinine and/or reductions in urine output. Any patient who meets the criteria for AKI should be reviewed to ascertain the cause of AKI and the severity of the injury sho...

Warfarin is a well-established cause of gross hematuria. However, impaired kidney function does not occur except in the rare instance of severe blood loss or clot formation that obstructs the urinary tract. It has been recently described an entity called warfarin-related nephropathy, in which acute kidney injury is caused by glomerular hemorrhage and renal tubular obstruction by red blood cell ...

OBJECTIVES To determine whether Pediatric Risk, Injury, Failure, Loss, End-Stage renal disease (pRIFLE) criteria serve to characterize the pattern of acute kidney injury in critically ill pediatric patients. To identify if pRIFLE score will predict morbidity and mortality in our patient's cohort. DESIGN Prospective cohort. SETTING Multidisciplinary, tertiary care, ten-bed PICU. PATIENTS A...

OBJECTIVE To compare the RIFLE (Risk, Injury, Failure, Loss and End-stage Renal Failure) and AKIN (Acute Kidney Injury Network) criteria for diagnosis of acute kidney injury after coronary artery bypass grafting. METHODS Retrospective cohort. 169 patients who underwent coronary artery bypass grafting from January 2007 through December 2008 were analyzed. Information was entered into a databas...
