    A 2 year old born 26 weeks premature presents to you in the neonatal follow-up clinic. Among the usual ventilatory requirements at birth, he also had a persistent patent ductus arteriosus which was treated with loop diuretics for 4 weeks. As a result, he developed nephrocalcinosis. His mother is asking you what the long-term implications are for her child’s kidney function.
