(A and B) Renal sonogram at presentation negative for hydronephrosis or nephrolithiasis. (C) Non-contrast computed tomography (CT) scan demonstrating a stone in the right kidney (arrow). No hydronephrosis is evident.

Illusion, Suspicion, and Obstruction: An Intriguing Case of Acute Kidney Injury

A 63-year-old man with a history of nephrolithiasis and neurogenic bladder requiring chronic indwelling urinary catheter was admitted for the management of urinary tract infection and acute kidney injury (AKI) with a serum creatinine level of 3.6 mg/dL (baseline approximately 1.9-2.2). He was initially brought to the emergency room for altered mental status. The patient […]

Abdominal computed tomography scan in the axial plane with contrast injection demonstrating entrapment of the right ureter (arrow) between right (6.1 cm) and left (13 cm) iliac artery aneurysms with peripheral calcifications.

A Dangerous Entrapment: Pelvic Aneurysms Causing Hydronephrosis

A 75-year-old patient with end-stage kidney disease on chronic hemodialysis was admitted with fever (38.5°C) and rigor. He was a heavy smoker and had long-standing diabetes and hypertension with abdominal aortic aneurysm (repaired 16 years prior with aortobifemoral graft) and peripheral artery disease with left above-knee amputation. Soon after admission, his blood pressure dropped and […]

Pelvic computed tomography scan showed a heterogeneous mass with central necrosis (star) compressing and invading the urinary bladder. A Foley catheter (arrow) can be seen within the residual portion of the bladder.

Pneumaturia and Nephrotic Syndrome Caused by a HiddenPelvic Malignancy

A 78-year-old female was admitted to the cardiac critical care unit with concerns for acute on chronic heart failure exacerbation. She had a history of nonischemic cardiomyopathy that had previously remained stable over a period of 15 years through standard medical management. Six months prior to admission, she developed dyspnea and lower extremity edema. She […]

Is Frailty a Predictor of Outcomes in Elderly Inpatients with Acute Kidney Injury? A Prospective Cohort Study

Frailty and acute kidney injury are independently associated with an increased risk of morbidity and mortality. The degree of frailty can be assessed by the Clinical Frailty Score (CFS). This study assessed whether an individual’s CFS was associated with acute kidney injury in acute elderly medical admissions and recorded the short-term outcomes. Methods This was […]

Computed tomography of the abdomen with contrast shows remarkable parietal peritoneal thickness (red arrow). Also noted is bilateral renal enlargement with innumerable renal cysts (yellow arrow), confirming diagnosis of Autosomal Dominant Polycystic Kidney Disease. There is a small amount of ascites and organization of loculated fluid collection (orange arrow) in the right upper quadrant. Small bowel dilatation (blue arrow) represents ileus.

Long-Term Peritoneal Dialysis May Result in Vascular Changes Within the Peritoneal Cavity, Leading to Reduced Efficacy of Intravenous Antibiotics in Treatment of Bacterial Peritonitis

Peritoneal dialysis is a home-based dialysis modality. In the US, 7.5% of the total dialysis population uses peritoneal dialysis.1 Peritoneal dialysis catheter-related peritonitis is a well-recognized complication, with an annual mortality rate as high as 16%.2 Although peritoneal dialysis-associated peritonitis treatment has been standardized, peritoneal dialysis catheter may require removal in cases of relapsing or refractory peritonitis […]

30-Day Readmissions After an Acute Kidney Injury Hospitalization

The risk of hospital readmission in acute kidney injury survivors is not well understood. We estimated the proportion of acute kidney injury patients who were rehospitalized within 30 days and identified characteristics associated with hospital readmission. Methods We conducted a population-based study of patients who survived a hospitalization complicated by acute kidney injury from 2003-2013 […]
