The data included the MCUG paediatric procedures for patients aged 0\u201315 years. The data were categorized into paediatric weight- and age-specific groups. Paediatric weight-specific groups were \u2264 5, 5 &lt; \u2013 10, 10 &lt; \u2013 20, and &gt;20 kg, and paediatric age-specific groups were \u2264 1, 1 &lt; \u2013 5, 5 &lt; \u2013 10, and &lt; 10 \u2013 15 years old.Results: Differences were observed in dose area product (DAP) and DRL results for age- and weight-specific methods, especially for paediatric age groups of 1 &lt; \u2013 5 and 5&lt; \u2013 10 years old compared with paediatric weight groups of 5 &lt; \u201310 kg and 10 &lt; \u2013 20 kg (p = 0.037 and 0.035). The proposed institutional DRLs for the MCUG fluoroscopy were 22.1, 63, 169, and 457 \u03bc Gy\u00b7 m2 for paediatric weight groups of \u2264 5, 5 &lt; \u2013 10, 10 &lt; \u2013 20, and &gt;20 kg. The estimated effective doses reached 0.81, 2.18, 2.08, and 2.5 mSv.Conclusion: The paediatric weight-specific method shows realistic and lower DAP and DRL values. The results of DRLs for the MCUG fluoroscopy were acceptable when compared with literature results.<\/jats:p>","DOI":"10.15537\/1658-3175.8852","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T19:19:56Z","timestamp":1790191196000},"page":"1634-1639","source":"Crossref","is-referenced-by-count":0,"title":["Estimating Radiation Dose and Proposing Institutional Diagnostic Reference Levels for Paediatric Fluoroscopy of Micturating Cystourethrogram: &lt;i&gt;Age- and Weight - Specific Comparisons&lt;\/i&gt;"],"prefix":"10.15537","volume":"47","author":[{"given":"Khalid M.","family":"Aloufi","sequence":"first","affiliation":[{"name":"Diagnostic Radiology Department, College of Applied Medical Sciences, Taibah University, Al-Madinah Al-Munawwarah, Kingdom of Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56029","published-online":{"date-parts":[[2026,9,14]]},"container-title":["Saudi Medical Journal"],"original-title":[],"language":"en","deposited":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T09:25:32Z","timestamp":1792142732000},"score":1,"resource":{"primary":{"URL":"https:\/\/smj.researchcommons.org\/journal\/vol47\/iss10\/7"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,14]]},"references-count":0,"journal-issue":{"issue":"10","published-online":{"date-parts":[[2026,9,14]]}},"URL":"https:\/\/doi.org\/10.15537\/1658-3175.8852","relation":{},"ISSN":["1658-3175"],"issn-type":[{"value":"1658-3175","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,14]]}}}
