Test Background Renal stones affect on average between 12-15 % of Caucasians (this figure varies among other population groups). Recurrence rates of up to 50 % within 5 years are not uncommon. Risk factors for recurrent renal calculi include low urine output, impaired renal function (assessed by U&E assay), hypophosphataemia and hypomagnesaemia, in addition to increased uric acid turnover, hypercalcaemia and hyperoxaluria.
