title: Hypercalciuria preceding IgA nephropathy in a child with haematuria.
abstract: We describe a child with isolated haematuria who was diagnosed and successfully treated for idiopathic hypercalciuria for 6 months, after which IgA nephropathy was demonstrated on renal biopsy performed due to the relapse of haematuria in spite of low calciuria levels. To our knowledge, this is the first case evaluated systematically in the literature shown to have IgA nephropathy while being followed up for idiopathic hypercalciuria.
