Hypercalciuria is a relatively common etiological factor in calcium urolithiasis1. It may be one of the manifestations of various abnormalities, such as hyperparathyroidism, renal tubular acidosis, sarcoidosis and malignancy. However, in the majority of cases it is classified as idiopathic2. In a previous study3 of a large series of patients (50 males and 24 females) with idiopathic hypercalciuric urolithiasis (i.e. idiopathic hypercalciuria associated with urolithiasis) we found that 20% of the examined patients had a family history of renal stones. Only one of these patients had a large enough family to allow a detailed study which is reported in this paper.
