Encrusted Urinary Tract Infections Due to Corynebacteria Species

Abstract: Introduction: Encrusted pyelitis and cystitis are peculiar disorders characterized by the calcification of the vesical, the pyelic, and/or the ureteral walls. These calcifications are composed of struvite and calcium carbonate-apatite due to the presence of Corynebacterium urealyticum. Methods:We have identified the clinical features and outcomes of 17 patients with encrusted pyelitis (n ¼ 15) or encrusted cystitis (n ¼ 2). Diagnosis was based on computed tomography scan and sonography including thickening and… Show more

“…24,29 KTRs with CAD had a higher prevalence of Corynebacterium, a bacterial genus also known for its potential uropathogenic activity in encrusted urinary tract infections. 27,45 The scarcity of studies and the low sample sizes in each study impose constraints on the conclusions. The studies designs and objectives lacked clear uniformity.…”

“…AST reduced the abnormally elevated abundance of Eubacterium in rats’ gut microbiota ( Chen et al, 2022 ). Encrusted pyelitis and cystitis are peculiar disorders characterized by calcification of the vesical, pyelic, and/or ureteral walls due to the presence of Corynebacterium urealyticum ( Sakhi et al, 2021 ). These calcifications are usually composed of struvite (ammonium magnesium phosphate) and calcium carbonate‒apatite crystals, caused by urea-splitting bacteria urinary infections ( Flannigan et al, 2014 ).…”

“…Corynebacterium striatum was originally considered a contaminant in many of these cases and was only subsequently considered to be the likely culprit. Corynebacterium urealyticum is the most common opportunistic pathogen, which is a cause of urinary tract infection and encrusting cystitis or pyelitis ( López-Medrano et al, 2008 ; Soriano and Tauch, 2008 ; Sakhi et al, 2020 ). Local inflammation caused by encrustations and pyelonephritis may lead to deterioration of renal function.…”
