The frequency of renal stones within Great Britain in a gouty and non-gouty population.

In a general practice survey carried out during 1976, the incidence of renal stones was found to be 82/100,000. When this population was divided into gouty and non-gouty subjects, the incidence of stones was found to be 870/100,000 respectively. Only 28% of the stone patients were found to have a chronic condition, including hyperuricaemia, which might predispose towards stone disease. In the population of 604 gout patients, 37 were found to have renal stones. These patients were diagnosed later than the average gout patient and also had a higher incidence of other chronic conditions.
