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...

PURPOSE Historically, the biopsy of renal masses was not advocated, and to date there remains some controversy on the role of biopsy for renal masses in making treatment decisions. With the widespread use of imaging methods, the incidental diagnosis of renal masses has increased, necessitating renal biopsies to better plan the management of these tumours. Here I review previous reports to defin...

UNLABELLED Ultrasound-guided percutaneous renal biopsy is an important technique for diagnosis of glomerular diseases, and the biopsy-induced life-threatening bleeding rarely happens. Primary systemic amyloidosis is a rare disease which may lead to organ dysfunction including arterial stiffness. The accessory renal artery is a kind of renal vascular variation which goes into the renal parenchym...

Background and Aim: Steroid-resistant nephrotic syndrome (SRNS) accounts for 10%-20% of all cases of idiopathic nephrotic syndrome. These patients are at risk of developing end-stage renal disease. The aim of this study was to determine the demographic characteristics, renal biopsy findings, response to immunosuppressive treatment, and prognosis in pediatric patients with SRNS.Materials and Met...

OBJECTIVE To determine the risk factors for adverse renal outcome in type 2 diabetic patients who underwent renal biopsy and were followed-up longitudinally. RESEARCH DESIGN AND METHODS We examined 68 consecutive patients with type 2 diabetes during the period of 1985-1999 who underwent renal biopsy for proteinuria > or =1 g/day, renal involvement (proteinuria or renal impairment) at the abse...
