Department of Radiology, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Via Albertoni 15, Bologna, Italy.

Purpose: This article reviews imaging manifestations of complicated pyelonephritis associated with chronic renal stones disease, in particular xanthogranulomatous pyelonephritis (XGP) and emphysematous pyelonephritis (EPN), as potential mimics of other renal diseases and malignances and provides helpful tips and differentiating features that may alert the radiologist to suspect a diagnosis of infection.

Materials And Methods: A retrospective review of the records from 6 adult patients (5 females and 1 male, mean age 72,3 years) with diagnosis of XGP associated with chronic nephrolithiasis and 7 adult patients (6 females and 1 male, mean age 59,3 years) with diagnosis of EPN associated with chronic nephrolithiasis from January 2010 to January 2020 was carried out. Computed tomography urography (CTU) with at least an unenhanced scan, and the parenchymal and excretory phases after contrast medium administration performed at our Teaching Hospital were included.

State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, Guangzhou, 510640, China; Beijing Key Laboratory of Lignocellulosic Chemistry, Beijing Forestry University, Beijing, 10083, China.

To develop functional and sustainable films from xylan-based hemicelluloses, beechwood xylan was firstly modified with p-dioxanone (PDO) through ring-opening graft polymerization (ROGP) and then reinforced by poly(vinyl alcohol) (PVA) to fabricate xylan-graft-poly(p-dioxanone)/PVA (XGP/PVA) ternary composite films. FT-IR spectra proved the existence of intermolecular hydrogen bonding interactions between the hydroxyl groups of XGP and PVA. SEM analysis outlined the good compatibility between the XGP matrix and the PVA filler in blending films. Read More
