Microbial Colonization Pattern of Indwelling Double J Stents in Children.

Background: Indwelling double-J-stent (DJ stent) kept post-urological procedures may cause urinary tract infections (UTIs) due to polymicrobial biofilm formation and colonisation.

Aims: To determine the incidence and microbiological characteristics of DJ stent related UTIs in a paediatric population.

Methods And Material: Patients under the age of 18 admitted for DJ stent removal following pediatric urological procedures were enrolled into the study.

Comparison of Urinary Biomarkers in Diagnosis of Ureteropelvic Junction Obstruction and Differentiation from Nonobstructive Dilatation.

Background And Aims: Differentiation of nonobstructive dilatation (NOD) from ureteropelvic junction obstruction (UPJO) is a challenge in children with antenatally detected hydronephrosis. The aim of this study is to compare the utility of urinary biomarkers: carbohydrate antigen (CA 19-9), neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule (KIM) in diagnosing UPJO.

Methods: A prospective study was conducted after obtaining ethical clearance between 2021 and 2022.
