We investigated prevalence and risk factors of nephrocalcinosis (NC) in recently born very low birth weight (VLBW) infants submitted to improved biological monitoring.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Retrospective, case\u2013control study in very preterm infants (&lt;\u200932\u2009+\u20096\u00a0weeks,\u2009\u2264\u20091500\u00a0g) admitted to a tertiary care unit during a 6-year period. Each case (ultrasound-diagnosed NC) was matched with two controls (no NC).

Prevalence was halved between 2012 (26.1%) and 2017 (11.8%). We included 265 infants, more than half being born before 28\u00a0weeks. Cases presented with more severe morbidity than controls, but reached statistical significance only in infants born\u2009&lt;\u200928\u00a0weeks (88.2% vs. 68.3%, <jats:italic>P<\/jats:italic>\u2009=\u20090.01). Protein, energy, calcium, phosphorus, and vitamin D intakes were similar in the two groups and did not change significantly over the study period. Weight gain was similar in the two groups. Exposure to furosemide (OR [IC95%]: 1.26 [1.02; 1.57]) and postnatal growth (1.65 [1.04; 2.67]) were independent risk factors of NC. NC resolved 12\u201318\u00a0months after diagnosis in 61% of infants.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Prevalence of NC is significant but can be reduced.
