[Choreito and Shakuyakukanzoto: their effects on facilitating the voiding of stones in the urinary tract].

We treated 30 patients having 37 urinary calculi in all, with " Choreito " (5 g/day) and " Shakuyakukanzoto " (5 g/day) to study whether these medicines hastened spontaneous calculus excretion. Within 2 months, 91% of the small calculi (5 X 5 mm and smaller), and 33% of the medium-sized (6 X 10 mm and below) were excreted. These results were similar to those obtained with conventional conservative treatment, and suggest that this therapy will be useful.
