A Scoping Review on Fluorescence-Guided Surgery in Paediatric Renal Tumours: Current Perspectives and Future Plans

Background/Objectives: Paediatric renal tumours, particularly Wilms tumours, have good survival outcomes following multimodal therapy; however, long-term morbidity related to nephrectomy and adjuvant treatment remains a major concern. As treatment paradigms increasingly prioritize nephron preservation and minimization of late effects, there is growing interest in technologies that can enhance intraoperative precision. Methods: A scoping review following the PRISMA guidelines was performed. We analysed articles on fluorescence for childhood renal tumours on 1 November 2025. Case reports, opinion articles, and narrative reviews were excluded. An Ovid Medline search with search terms "Kidney neoplasm" AND "Fluorescent Dyes", along with a Cochrane trials registry search for "kidney" AND "neoplasm" AND "Fluorescent Dye", was performed, along with a hand search of citations. Results: The Ovid Medline search yielded 21 results, and the Cochrane trials search gave 4 results. Following review, five papers were included, of which one was an ex vivo study and one was a randomised, controlled trial that is currently recruiting. Conclusions: There is a lack of evidence around the use of near-infrared fluorescence in paediatric renal tumour surgery. This review summarizes the key current findings and future perspectives.
