BACKGROUND Trauma is the leading cause of childhood morbidity and mortality. Abdominal bleeding is one of the common causes of mortality due to trauma. Angiography and embolization are well recognized as the primary treatments in certain cases of acute traumatic hemorrhage in adults; however, evidence is lacking in the pediatric population. OBJECTIVES To assess the safety and efficacy of tran...

In the pediatric patient, traumatic injury is the leading cause of death and blunt trauma is themost commonmechanism of injury. Renal injuries account for 8 to 12% of pediatric blunt abdominal injuries. Children, more so than adults, are prone to sustain major renal injury due to blunt trauma given the relatively large size of pediatric kidneys and decreased protection in children.1–3 The prima...

Objectives: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis is an autoimmune disease usually seen in middle-aged and older adults but which is rare in children and adolescents. We sought to determine if there has been a change in the incidence of this disorder. Methods: Single-center, retrospective review. Results: Over the last 2 years, we have encountered a striking increase...

CONTEXT The first renal biopsy was carried out more than a century ago, but its widespread introduction into clinical use, beginning in the 1950s, helped develop nephrology into the powerful subspecialty of internal medicine that it is today. In the past 25 years, the use of the spring-loaded biopsy gun, in combination with newer visualization techniques, including ultrasound and computed axial...

Renal biopsy is an essential tool for the diagnosis of several renal diseases. The first renal biopsies were performed in 1923 as open surgical procedures (Gwyn, 1923). The percutaneous approach has been part of the clinical practice since 1951 (Iversen & Brun, 1951). A few years later, a description of the procedure with the patient placed in a prone position was published (Kark & Muehrcke, 19...

Introduction: Nephrotic syndrome is a clinical of heavy proteinuria and hypoalbuminemia or hypoproteinemia. Renal biopsy fundamental to assess not only the type but also degree disease activity. The overall prognosis response treatment often depend on severity histological lesions their reversibility.1,2 Case Presentation: An eighteen years old man with nephrotic planned for kidney biopsy. This...

PURPOSE We evaluated the safety and accuracy of ultrasonography-guided percutaneous core biopsy collection in patients with renal masses. MATERIALS AND METHODS From June 2008 to August 2012, 30 percutaneous core biopsies of renal masses were performed. The biopsies obtained were small tumors (<4 cm) with ambiguous radiologic findings or that met classic renal biopsy indications. The biopsy re...

Renal biopsy is an important investigation for suspected renal parenchymal disease and is frequently required in clinical practice. Use of ultrasound and automated spring loaded device has reduced the rate of complications associated with the procedure. However, occasionally dramatic situations of hemodynamic instability arise due to bleeding after renal biopsy. Only four cases of lumbar artery...
