INTRODUCTION Percutaneous renal biopsy in patients with renal masses is increasing. We investigated the accuracy of percutaneous renal mass biopsy results in patients undergoing evaluation of solid renal masses. METHODS A retrospective review was performed of patients in the Kaiser Permanente Southern California Region who underwent computed tomography or ultrasound-guided percutaneous renal ...

There has also been an increase in renal biopsies in these patients. The aim of this study was to investigate the influence of the renal biopsy...

Despite intensive treatment, steroid-resistant nephrotic syndrome (NS) often progresses to endstage renal disease. Therefore, a more accurate and quick histological diagnosis is required to properly treat such patients. The aim of this study was to introduce a novel approach to the histological diagnosis of pediatric NS by low vacuum scanning electron microscopy (LVSEM) and to describe the morp...

BACKGROUND The incidence of idiopathic nephrotic syndrome (INS) varies among countries, with Asia reporting a higher incidence in comparison with Western countries. We investigated the epidemiologic features of INS and attempted to identify factors that predispose individuals to develop end-stage renal disease (ESRD). METHODS Claims data from the Taiwanese National Health Insurance program fr...

We present here a case of a 9-year-old boy with bilateral anterior uveitis and an extremely elevated urinary β2-microglobulin level (25,400 μg/l). The normal range for urinary excretion of β2-microglobulin is 0-300 μg/l. In patients with tubulointerstitial nephritis and uveitis syndrome (TINU), elevations typically range from 1,260 to 5,160 μg/l. Renal biopsy was pursued, and significant granul...

In this review, we identify important challenges facing physicians responsible for renal and cardiac transplantation in children based on a review of the contemporary medical literature. Regarding pediatric renal transplantation, we discuss the challenge of antibody-mediated rejection, focusing on both acute and chronic antibody-mediated rejection. We review new diagnostic approaches to antibod...

BACKGROUND AND OBJECTIVES Skepticism about performing renal biopsies is often because of uncertainty regarding risk of complications. The aim of this study was to evaluate safety and relevant complications of renal biopsies in pediatric and adult patients in a large national registry study. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Kidney biopsies reported in the Norwegian Kidney Biopsy R...

OBJECTIVE To determine whether the absence of mesangial IgG deposits is associated with the absence of elevated blood levels of galactose-deficient IgA1 (Gd-IgA1) in pediatric patients with IgA nephropathy (IgAN). DESIGN AND METHODS Serum Gd-IgA1 levels were determined by ELISA using an N-acetylgalactosamine-specific lectin from Helix aspersa. Levels of Gd-IgA1 above the 90th percentile for h...
