Abstract
It was supported that Yarbro & Simpson's method (1956) was most reliable to estimate the urinary excretion of oxalic acid at present. We measured the urinary oxalic acid excretion in 8 normal adults, 13 patients with simple calculus and 6 patients with multiple or staghorn calculi of upper urinary tracts. All calculi contained the oxalate, certified with infrared spectra.The following conclusions resulted:1) Urinary oxalic acid excretion in normal adults was 12.6 to 59.0mg per day.2) It was within normal range in the patients with simple calculus (11.7 to 60.5mg per day).3) The slightly increased excretion of urinary oxalic acid was found in the patients with multiple or staghorn calculi (28.3 to 62.1mg per day).4) There was no correlation between the urinary excretion of oxalic acid and the contents of oxalate in calculi.
