BACKGROUND The role of calcium oxalate crystals and deposits in UTI pathogenesis has not been established. The objectives of this study were to identify bacteria present in pediatric urolithiasis and, using in vitro and in vivo models, to determine the relevance of calcium oxalate deposits during experimental pyelonephritis. METHODS Pediatric kidney stones and urine were collected and both cu...

INTRODUCTION Chronic pyelonephritis is associated with progressive renal scarring and occurs, most of the time, in patients with major anatomical anomalies, including urinary tract obstruction, calculi, renal dysplasia or vesicoureteric reflux. We report the computed tomography imaging findings of a patient with chronic pyelonephritis appearing as a renal sinus mass. To our knowledge, it is the...

INTRODUCTION The role of vitamin A in re-epithelialization of the damaged mucosal surfaces has been documented. The aim of this study was to evaluate the role of vitamin A in preventing renal scaring after acute pyelonephritis in children. MATERIALS AND METHODS This clinical trial study was conducted in children with acute pyelonephritis in Mofid Children Hospital (Tehran, Iran). Patients wer...

BACKGROUND Urinary tract infection is the most common health problem affecting millions of people each year, mainly caused by a large genetically heterogeneous group of Escherichia coli called uropathogenic E. coli This study investigates the genotypic analysis of E. coli strains isolated from patients with cystitis and pyelonephritis. METHODS During 2008-2009, 90 E. coli strains were analyze...

Emphysematous Pyelonephritis (EPN) is a severe, necrotizing, life threatening infection of the renal parenchyma and management is not standardised due to scarcity of literature. We present 3 patients with this rare entity. All 3 patients were of class III on CECT findings based on Huang's classification and had more than two risk factors. Our first patient underwent percutaneous drainage of his...

OBJECTIVES. To evaluate the role of primary vesicoureteral reflux (VUR) in increasing the frequency and severity of urinary tract infections (UTIs) and renal parenchymal damage among patients with acute pyelonephritis and to determine whether urinary antibiotic prophylaxis reduces the frequency and/or severity of UTIs and/or prevents renal parenchymal damage among patients with mild/moderate VU...
