Previous studies have demonstrated that enteral nutrition mixtures rich in sodium and poor in calcium may promote stone formation in pediatric patients, but a confirmation study is lacking. Moreover, the occurrence of urinary stones and heterotopic ossifications has not been studied regarding incidence. We thus conducted a prospective observational study in an unselected pediatric population with acquired brain injury, to estimate the incidence of urinary stones and heterotopic ossifications and analyze the associated factors. Methods: Prospective observational study: We recruited all patients with enteral nutrition consecutively admitted to our brain injury rehabilitation unit during a 5-year time-frame. We collected clinical data regarding nutrition, infections, blood and urine exams performed, neurological examinations, and physical examinations. Results: The prospective design allowed us to observe that no patient developed heterotopic ossifications, while urinary stones were found in 12.5% of patients and gravel in 14.6%. Factors associated with stone formation were having a worse subacute GCS, having done intense physical activity before injury, receiving bladder catheterizations, having a higher urine pH, and having higher blood potassium levels. The composition of the enteral nutrition did not influence stone formation, although the nutrition mixtures contained levels of vitamin C and proteins considerably higher than the recommended reference ranges. Conclusions: We have provided an observation of the incidence of urolithiasis in pediatric patients in rehabilitation, which was lacking from the literature. Enteral nutrition, at the amounts received by the patients studied herein, does not seem to have a role in stone formation. We identified a set of risk factors that can be useful for clinicians to pinpoint patients at an increased risk of developing stones.<\/jats:p>","DOI":"10.3390\/nu17050883","type":"journal-article","created":{"date-parts":[[2025,3,4]],"date-time":"2025-03-04T05:41:51Z","timestamp":1741066911000},"page":"883","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prospective Study of Urinary Stone Formation in Pediatric Patients with Acquired Brain Injury: A Focus on Incidence and Analysis of Risk Factors"],"prefix":"10.3390","volume":"17","author":[{"given":"Sara","family":"Galbiati","sequence":"first","affiliation":[{"name":"Scientific Institute IRCCS Eugenio Medea, 23842 Bosisio Parini, LC, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Federica","family":"Locatelli","sequence":"additional","affiliation":[{"name":"Scientific Institute IRCCS Eugenio Medea, 23842 Bosisio Parini, LC, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5977-8090","authenticated-orcid":false,"given":"Fabio Alexander","family":"Storm","sequence":"additional","affiliation":[{"name":"Scientific Institute IRCCS Eugenio Medea, 23842 Bosisio Parini, LC, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3800-5697","authenticated-orcid":false,"given":"Marco","family":"Pozzi","sequence":"additional","affiliation":[{"name":"Scientific Institute IRCCS Eugenio Medea, 23842 Bosisio Parini, LC, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8414-6565","authenticated-orcid":false,"given":"Sandra","family":"Strazzer","sequence":"additional","affiliation":[{"name":"Scientific Institute IRCCS Eugenio Medea, 23842 Bosisio Parini, LC, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Miller, F., Bachrach, S., Lennon, N., and O\u2019Neil, M.E.
