Uric acid calculi: results of conservative treatment.

A total of 140 patients with uric acid diathesis have been treated for the last five years with a standardized mixture of sodium and potassium citrate and citric acid (Uralyt U) together with forced fluid intake and, if necessary, the addition of allopurinol. The results have been encouraging; 80 per cent of the patients showed complete dissolution of the stones and relief of symptoms.
