RESUMEN
OBJECTIVES: Given high and growing prevalence rate of urolithiasis in most societies as well as the problems caused by this issue, it is necessary to apply more cost-effective and safer therapeutic methods, which are accessible for all the individuals worldwide. Therefore, this study aimed to investigate efficacy of herbal medicines named Cynodon dactylon and Dolichos biflorus on solving and excretion of renal and urinary tract stones in patients with urolithiasis. METHODS: This study included 96 patients with urolithiasis who were randomly allocated into three groups. The first group received the extract of D. biflorus seeds (1,600 mg), the second group received extract of C. dactylon rhizome (1,600 mg) and the third group received placebo for 21 days. In this study, we used an hydroalcoholic extract of D. biflorus and C. dactylon prepared by Soxhlet method. For each patient, the size of the stones, the amount of calcium in the urine, the number of stones excreted and their chemical substance type were measured. RESULTS: In this study, changes were observed at the significance level in the interventions groups of 1 and 2, and the placebo group in the left kidney, so that changes in size of the stone in left kidney as intergroup were significantly different in these three groups (p=0.02). The mean of changes in stone size in left kidney in the group C. dactylon was 3.78 ± 7.1 and in the group D. biflorus, it was 0.27 ± 0.6. CONCLUSIONS: A significant difference in the results of this study show that C. dactylon rhizome and D. biflorus seed extracts are able to decrease the size of the stone and can be effective on kidney stones excretion.

To screen the active fractions with lithagogue effects of Pyrrosia lingua from Guizhou province and preliminarily investigate its mechanism. The rats were fed with 1% ethylene glycol and 2% ammonium chloride to establish the nephrolithiasis models, which were used to evaluate thelithagogue effects of different polar fractions of P. lingua from Guizhou province. The level of urinary calcium and oxalic acid in urine, renal calcium, oxalic acid, superoxide dismutase (SOD), catalase(CAT) and malondialdehyde (MDA) in renal tissues,as well as crystalline deposit and lithogenesis in renal tissues and the levels of creatinine(Cr) and blood urea nitrogen (BUN) in the serum were detected. The effective compounds were inferred from the analysis of active fractions extract based on LC-MS technology. Petroleum ether fraction and dichloromethane fraction of P. lingua from Guizhou province can reduce renal oxalic acid and renal calcium concentration, increase urinary oxalic acid and urine calcium, with significant inhibitory effect on the formation of renal calculus in rats, significantly increase SOD and CAT activities in renal tissues, and significantly reduce MDA levels. LC-MS analysis showed that the caffeine, citric acid and tartaric acid among the compounds from petroleum ether fraction and dichloromethane fraction had lithagogue effects. Both the petroleum ether fraction and dichloromethane fraction of P. lingua from Guizhou province showed good effect on prevention and treatment of calculus in middle dose groups, and the mechanism may be associated with antioxidation, reducing calcium oxalate crystal deposition, and promoting calcium oxalatecrystal release, in addition, caffeine, citric acid and tartaric acid had lithagogue effects.

RESUMEN
Objective To observe clinical effect of treating urinary calculi with Lithagogue decoction combined with western medicine. Methods 32 cases patients with urinary calculi were randomly recruited into a control group and a treatment group. The control group was treated with anisodamine, ivgtt, and progesterone, im, and the treatment group was treated with lithagogue decoction based on the control group. The clinical effect was observed in both groups. Results The clinical effect was 93.8% and 68.7% in the treatment group and the control group respectively, the difference showing statistic significance (χ~2=3.459, P<0.05) .Conclusion The treatment of urinary calculi with Lithagogue decoction combined with western medicine is better than with western medicine only.
