title: Effects of dietary fat on the urinary risk factors of calcium stone disease.
abstract: OBJECTIVE
  To assess the association between dietary fat and various urinary risk factors of calcium stone disease in a group of calcium stoneformers attending an outpatient stone clinic.
  
  
  METHODS
  Mean daily fat intake from self-recorded 4-day dietary food records and mean 24-hour urinary risk factors from two separate collections were evaluated in 476 patients selected randomly from an adult population attending an outpatient stone clinic for the first time.
  
  
  RESULTS
  Mean daily total fat intake for men and women was significantly different at 105.6 and 78.1 g, respectively. Examination of the relationship between total fat intake and 24-hour urinary volume, pH, and excretions of magnesium, citrate, oxalate, calcium, and uric acid revealed no significant regressions in men and only a weak association between fat intake and urinary uric acid in women.
  
  
  CONCLUSIONS
  Dietary fat does not have a significant effect on the urinary risk factors of calcium stone disease.
