Objective: To observe the clinical effect of Shiwei Lishi Granule on small
urinary calculi. Methods: 78 patients were randomly divided into two groups, 40 in
the treatment group and 38 in the control group. Four weeks follow-up was used as the
end point. Results: the 4-week effective rate of the treatment group was 85%, and that
of the control group was 60.5%. The difference was statistically significant (P < 0.05).
Conclusion: the therapeutic effect of Shiwei Lishi granule combined with western
medicine on small urinary calculi was better than that of Western medicine alone.
