Abstract
Treatment with alpha-blockers has been used in many studies to facilitate stone clearance after extra-corporeal shock wave lithotripsy (ESWL), based on mediating ureteral wall relaxation. Ureteral wall edema is another barrier against the stone passage. We aimed to compare the effectiveness of boron supplement (due to its anti-inflammatory effect) and tamsulosin in the passage of stone fragments after ESWL. Eligible patients after ESWL were randomly assigned to two groups and were treated with boron supplement (10 mg/BD) or tamsulosin (0.4 mg per night) for 2 weeks. The primary outcome was the stone expulsion rate according to the remained fragmented stone burden. The secondary outcomes were the time of stone clearance, pain intensity, drug side effects, and the need for auxiliary procedures. In this randomized control trial, 200 eligible patients were treated with boron supplement or tamsulosin. Finally, 89 and 81 patients in the two groups completed the study, respectively. The expulsion rate was 46.6% in the boron and 38.7% in the tamsulosin group, which there was no statistically significant difference between the two groups (p = 0.003), as well as the time of stone clearance (7.47 ± 22.4 vs 6.52 ± 18.45, days, p = 0.648, respectively), after 2-week follow-up. Moreover, pain intensity was the same in both groups. No Significant side effects were reported in the two groups. Boron supplement could be effective as adjuvant medical expulsive therapy after ESWL with no significant side effects in short-term follow-up.

Abstract
Boron plays roles in the metabolism of calcium, vitamin D, steroid hormones, healthy bone development, and maintenance of cell membranes. The biological effects of boron are dose-dependent but follow a U-shaped pattern, rendering it important to define the active range. The studies of Bahadoran et al. on rats and Naghii et al. on humans showed that low doses of boron (3 and 10 mg/day) prevented kidney stone formation. The aim of this study was to determine whether high doses of boron have an anti-urolithiatic or antioxidant effect on nephrolithiasis in an experimental rat model. The study was conducted on 50 adult male Wistar rats randomized to five groups. Nephrolithiasis was induced with water containing 0.75% ethylene glycol (EG) and 2% ammonium chloride (AC). This treatment was given to animals in all groups for 10 days, except the positive and negative controls. Simultaneously, groups 2, 3, and 4 were given boric acid via gavage at doses of 25, 50, and 100 mg/kg/day (equivalent to 4/8/16 mg boron respectively) as the source of boron. Animals in the negative and positive control groups were given 6 μL/g distilled water without boric acid. At day 10, intra-cardiac blood samples were drawn from all animals. The right and left kidneys were removed for biochemical and histopathological examinations, respectively. The groups were compared with respect to serum urea, creatinine, calcium, phosphorous, total antioxidant status (TAS), total oxidant status (TOS), serum paraoxonase (PON1) activity, tissue calcium and oxalate levels, and stone burden as determined by histopathological examination. Serum urea and creatinine levels were significantly higher (p < 0.001 and p < 0.05, respectively), while serum calcium and phosphorous levels were significantly lower (p < 0.001 and p < 0.001, respectively), in animals given EG/AC compared to negative controls. No significant differences were detected in serum calcium, phosphorous, urea, or creatinine levels between animals treated with boron and positive controls (p > 0.05). Serum PON1 activity was significantly lower in animals given EG/AC than in negative controls (p < 0.001), while no significant difference in serum PON1 level was detected between rats treated with boron and positive controls. No significant differences were detected in vitamin D, TAS, TOS, tissue calcium, or tissue oxalate levels among groups. No stone formation was detected on histopathological examination in negative controls. No significant differences were found in stone formation between rats treated with boron and positive controls. Based on this study, high doses of boron had no protective effect against nephrolithiasis and oxidative stress.

Abstract
Urolithiasis affects around 10% of the US population with an increasing rate of prevalence, recurrence and penetrance. The causes for the formation of most urinary calculi remain poorly understood, but obtaining the chemical composition of these stones might help identify key aspects of this process and new targets for treatment. The majority of urinary stones are composed of calcium that is complexed in a crystalline matrix with organic and inorganic components. Surprisingly, mitigation of urolithiasis risk by altering calcium homeostasis has not been very effective. Thus, studies to identify other therapeutic stone-specific targets, using proteomics, metabolomics and microscopy techniques, have been conducted, revealing a high level of complexity. The data suggest that numerous metals other than calcium and many nonmetals are present within calculi at measurable levels and several have distinct distribution patterns. Manipulation of the levels of some of these elemental components of calcium-based stones has resulted in clinically beneficial changes in stone chemistry and rate of stone formation. The elementome--the full spectrum of elemental content--of calcium-based urinary calculi is emerging as a new concept in stone research that continues to provide important insights for improved understanding and prevention of urinary stone disease.

Abstract
Administration of natural antioxidants has been used to protect against nephrolithiasis. Urolithiasis was induced by ethylene glycol (EG) in Wistar rats. For 4 weeks, group 1 (control) was fed with a standard commercial diet. Group 2 received the same diet with 0.75% of EG. Group 3 received EG plus the diet and water added with antioxidant nutrients and lime juice as the dietary source of citrate (EG + AX). Group 4 same as group 3 with no EG in water. For 8 weeks, group 5 was fed the standard diet with EG in water for the first 28 days, followed by no EG. Group 6 received the diet with EG for the first 28 days, followed by discontinuation of EG and addition of antioxidant nutrients. Group 7 were provided the diet with antioxidant nutrients for 8 weeks. Group 8 received the diet with antioxidant nutrients for 4 weeks, followed by antioxidant nutrients with EG for the next 4 weeks. Blood samples were collected and kidneys were removed. The size and the mean number of crystal deposits in EG-treated groups was significantly higher than the EG-treated groups, added with antioxidant nutrients and lime juice. After 4 weeks, the mean concentration of malondialdehyde in group 2 was higher than the group 3, and significantly lower in group 4; and in groups 7 after 8 weeks, as well. After 8 weeks, supplementation developed less mean number of deposits in group 6 as compared to group 5; and in group 8, the crystal deposits was substantially less than either group 2 or group 5 (EG-treated rats). Elevated concentration of androgens (as promoters of the formation of renal calculi) as a result of EG consumption decreased following antioxidant supplementations. Results showed a beneficial effect of antioxidant and provided superior renal protection on treating and preventing stone deposition in the rat kidney.
