Understanding biomarkers of kidney injury among CKD and WT patients is of high interest due to its potential implications for diagnosis, prognosis, and treatment strategies. This study enrolled twenty pediatric patients with WT (stage I\u2013IV), forty with CKD (stage I\u2013V), and twenty healthy volunteers. Urine samples were collected and six urine biomarkers (calbindin, clusterin, GST-\u03c0, IL-18, KIM-1, MCP-1) associated with kidney injury were assessed using the Bio-Plex Pro RBM Human Kidney Toxicity Assays kit (Bio-Plex Manager software 4.0). A comparative analysis of biomarker levels across the three groups revealed distinct patterns. Creatinine levels were notably elevated in CKD (1.32 \u00b1 1.9) compared to WT (0.64 \u00b1 0.26) and the control group. Tested biomarkers were calculated per milligram of urine creatinine, and all the differences among the groups were statistically significant. Pearson\u2019s correlation coefficients showed strong interplay among CKD biomarkers. This study identified variations in biomarker patterns among WT and CKD patients. Understanding biomarker interactions may provide future diagnostic approaches for pediatric kidney conditions.<\/jats:p>","DOI":"10.3390\/ijms26136238","type":"journal-article","created":{"date-parts":[[2025,7,1]],"date-time":"2025-07-01T05:28:28Z","timestamp":1751347708000},"page":"6238","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative Evaluation of Urinary Biomarkers in Wilms Tumor Survivors and Children with Chronic Kidney Disease"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8537-4404","authenticated-orcid":false,"given":"Pawel","family":"Dubiela","sequence":"first","affiliation":[{"name":"Department of Regenerative Medicine and Immune Regulation, Medical University of Bialystok, 15-089 Bialystok, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8762-8866","authenticated-orcid":false,"given":"Katarzyna","family":"Taranta-Janusz","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Nephrology, Medical University of Bialystok, 15-089 Bialystok, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0540-8040","authenticated-orcid":false,"given":"Katarzyna","family":"Kono\u0144czuk","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Oncology and Hematology, Medical University of Bialystok, 15-089 Bialystok, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karolina","family":"Konstantynowicz-Nowicka","sequence":"additional","affiliation":[{"name":"Department of Physiology, Medical University of Bialystok, 15-089 Bialystok, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7407-8156","authenticated-orcid":false,"given":"Adrian","family":"Chabowski","sequence":"additional","affiliation":[{"name":"Department of Physiology, Medical University of Bialystok, 15-089 Bialystok, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulina","family":"Szymanska-Rozek","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics, Informatics and Mechanics, University of Warsaw, 00-927 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7667-7953","authenticated-orcid":false,"given":"Eryk","family":"Latoch","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Oncology and Hematology, Medical University of Bialystok, 15-089 Bialystok, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2999","DOI":"10.1200\/JCO.2015.62.1888","article-title":"Advances in Wilms Tumor Treatment and Biology: Progress Through International Collaboration","volume":"33","author":"Dome","year":"2015","journal-title":"J.
