The prevalence of nephrocalcinosis (NC) in preterm neonates in recent reports is 7-41%. The wide range in prevalence is a consequence of different study populations and ultrasound equipment and criteria, in addition to a moderate interobserver variation. NC in preterm neonates has a multifactorial aetiology, consisting of low gestational age and birth weight, often in combination with severe respiratory disease, and occurs as a result of an imbalance between stone-promoting and stone-inhibiting factors.

Objective: The aim of our study was to examine long-term effects of nephrocalcinosis in prematurely born children.

Patients And Methods: Preterm neonates (gestational age <32 weeks) with (n = 42) and without (n = 32) nephrocalcinosis were prospectively studied at a mean age of 7.5 (+/-1.

Nephrocalcinosis (NC) occurs frequently in preterm neonates. A high U-calcium/citrate is one of the contributing factors to the development of NC. In stone-forming children and adults citrate supplementation is a successful preventive therapy.

The aim of the study was to evaluate the natural course of nephrocalcinosis (NC) in preterm neonates and the effect of NC on blood pressure and renal glomerular and tubular function. In a prospective observational study of 201 preterm neonates (gestational age <32 weeks) NC was present at term in 83 patients (41%), who were subsequently examined at 6, 12, and 24 months, and until August 2000 annually (with a maximum of 4 years) if NC persisted. Examination consisted of blood pressure measurement, renal ultrasonography, and glomerular and tubular function tests.
