Urinary NGAL and renalase as non-invasive biomarkers for detection of deterioration of kidney function and kidney scarring in children with neurogenic bladder.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundUrinary biomarkers such as neutrophil gelatinase-associated lipocalin (NGAL) and renalase hold promise for assessing kidney health, yet their role in the pediatric neurogenic bladder (NB) remains unclear. This study evaluates their clinical utility in detecting kidney dysfunction and their association with disease severity.
methodsA cross-sectional study included 44 patients with NB and 45 age- and gender-matched healthy children (reference group). Urinary NGAL and renalase levels were measured using ELISA. Patients with NB were categorized based on glomerular filtration rate (GFR) and kidney scarring. Biomarker levels were compared using the Mann-Whitney U test, and their correlations with functional parameters (DTPA, DMSA) were assessed using Spearman's correlation.
resultsUrinary NGAL and renalase levels were significantly higher in patients with NB than in the reference group (NGAL: 31.86 vs. 23.40 pg/mg creatinine, p = 0.0345; renalase: 2.75 vs. 1.76 ng/mg creatinine, p = 0.0493). Patients with NB with GFR < 60 mL/min/1.73 m
conclusionsUrinary NGAL and renalase are elevated in pediatric patients with NB, particularly in those with kidney dysfunction, and correlate with GFR and kidney scarring. These findings highlight their potential as non-invasive markers for early detection and monitoring of kidney impairment in NB. Future longitudinal studies are warranted to validate their diagnostic and prognostic utility.
