Metabolic studies or renal stone disease

Hypercalciuria was identified in 63% of Iraqi patients with renal stone disease. The hypercalciuric patients were classified according to their serum calcium, phosphate, parathyroid hormone, and urinary calcium and phosphate into: primary hyperparathyroidism [2%], and idiopathic hypercalciuria [61%], which was identified as absorptive [27%], renal calcium leak [30%] and renal phosphate leak [4%]. The disorder of nonhypercalciuric patients [37%] was mostly attributed to bacteria infections and bilhariziasis. Calcium oxalate and [or] phosphate were the main constituent of stones collected from idiopathic hypercalcuria patients. Ammonium urate stones were found in five children, which comprises 4% of the total number of patients
