Increased fractional excretion of sulphate in stone formers.
This study was performed to determine urinary sulphate excretion in patients with renal stone disease. Stone formers showed a significantly higher fractional excretion of sulphate than control subjects; 80% of stone formers had fractional excretions > 0.26. No significant relationship was established between increased urinary sulphate excretion and any identifiable metabolic disorder, or the recurrence rate of stone episodes. The increase in fractional excretion of sulphate appears to be a more prevalent tubular defect among stone formers than has hitherto been reported.
