This review examines the strengths, limitations, and clinical applications of various imaging modalities, with a focus on pediatric populations. Materials and Methods: A narrative review was conducted, synthesizing current literature on ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, and voiding cystourethrography (VCUG). Relevant studies were selected based on diagnostic accuracy, clinical utility, and safety considerations. Results: US is the preferred first-line imaging due to its safety, accessibility, and cost-effectiveness. CT excels in detecting renal calculi, trauma, and malignancies but is limited by radiation exposure. MRI offers superior soft tissue contrast without radiation but is costly and often requires sedation. Nuclear medicine evaluates renal function and scarring, while VCUG remains the gold standard for diagnosing vesicoureteral reflux and posterior urethral valves. Conclusions: Imaging modalities are vital for diagnosing and managing urinary tract disorders, with selection based on clinical needs, patient age, and safety. Ultrasound is the primary choice for its non-invasiveness and cost-effectiveness, while CT, MRI, nuclear medicine, and VCUG provide essential structural and functional insights. A balanced approach ensures accuracy while minimizing patient risk, especially in pediatrics.<\/jats:p>","DOI":"10.3390\/medicina61040696","type":"journal-article","created":{"date-parts":[[2025,4,10]],"date-time":"2025-04-10T10:47:41Z","timestamp":1744282061000},"page":"696","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Imaging Diagnosis of Major Kidney and Urinary Tract Disorders in Children"],"prefix":"10.3390","volume":"61","author":[{"given":"Ahmad","family":"Aldughiem","sequence":"first","affiliation":[{"name":"Department of Nephrology, Wright State University, Dayton Children\u2019s Hospital, One Children\u2019s Plaza, Dayton, OH 45404, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"552","DOI":"10.1053\/j.ajkd.2018.12.029","article-title":"Renal Imaging: Core Curriculum 2019","volume":"73","author":"Fried","year":"2019","journal-title":"Am.
