ABSTRACT

The majority of renal calculi in children were considered to be of infective origin. A recent review suggests a shift in the epidemiology of renal stone disease in the UK, with a metabolic abnormality detected in 44 percent of children; 30 percent were classified as infective and 26 percent idiopathic. Hypercalciuria (57 percent) was the most common metabolic abnormality, followed by cystinuria (23 percent), hyperoxaluria (17 percent), hyperuricosuria (2 percent), and unclassified hypercalcemia (2 percent).
