Abstract

Kidney stones are a common problem for which inadequate prevention exists. We recruited ten recurrent kidney stone formers with documented calcium oxalate stones into a two phased study to assess safety and effectiveness of Cystone®, an herbal treatment for prevention of kidney stones. The first phase was a randomized double-blinded 12 week cross over study assessing the effect of Cystone® vs. placebo on urinary supersaturation. The second phase was an open label one year study of Cystone® to determine if renal stone burden decreased, as assessed by quantitative and subjective assessment of CT. Results revealed no statistically significant effect of Cystone® on urinary composition short (6 weeks) or long (52 weeks) term. Average renal stone burden increased rather than decreased on Cystone®. Therefore, this study does not support the efficacy of Cystone® to treat calcium oxalate stone formers. Future studies will be needed to assess effects on stone passage, or on other stone types.
