“…However, the calciuric effect of mineral waters may be more accentuated in stone formers than in controls (Mirzazadeh et al, 2012), so that some experts claim caution in advising a patient with calcium oxalate or calcium phosphate stones to drink waters with a high calcium content (Karagulle et al, 2007). Moreover, the bioavailability of calcium in mineral waters depends on many factors that are also related with the ionic composition of water, such as sodium, magnesium and chloride content.…”

Adequate hydration, as to maintain urinary volume over 2 L/day, has long been considered as the cornerstone medical prescription for preventing nephrolithiasis. However, scientific evidence about what kind of water stone formers should drink and about the effects of other beverages on urinary stone risk factors is sometimes unclear. Moreover, the recommendation that water therapy prevents kidney stone recurrence relies on only one randomized controlled trial, even if more epidemiologic and basic science studies seem to support this assumption. Therefore, in this review we analyze current evidence that support water therapy in nephrolithiasis and we highlight the possible effects of different types of water and other beverages on lithogenic risk, giving some practical recommendations for what stone formers should be advised to prevent recurrence.

“…Intake of hard water has potential to decrease the risks of cardiovascular disease [55]. The importance of mineral contents in the drinking water is proven, when its intake is able to reduce calcium oxalate stone in the kidney of people that consume drinking water rich in minerals such as Mg, Ca, and bicarbonate [56–58]. In contrast, consumption of low calcium content in the drinking water has resulted in the hip fracture incident in the Norwegian population [59].…”

Deep sea water (DSW) commonly refers to a body of seawater that is pumped up from a depth of over 200 m. It is usually associated with the following characteristics: low temperature, high purity, and being rich with nutrients, namely, beneficial elements, which include magnesium, calcium, potassium, chromium, selenium, zinc, and vanadium. Less photosynthesis of plant planktons, consumption of nutrients, and organic decomposition have caused lots of nutrients to remain there. Due to this, DSW has potential to become a good source for health. Research has proven that DSW can help overcome health problems especially related to lifestyle-associated diseases such as cardiovascular disease, diabetes, obesity, cancer, and skin problems. This paper reviews the potential health benefits of DSW by referring to the findings from previous researches.

“…Two of the 19 studies had to be excluded from quantitative analysis because of the following reasons: (1) Milewski JB et al only published mean values as their outcome measurement, without standard deviation and p values [25]; and (2) Neimark AI et al reported implausible data, since 24h urinary uric acid amount changed from 0.8±2.4 to 8.3±2.23 mmol/d after the treatment of Serebrianyi Kliuch mineral water [26]. Three of the remaining 17 studies were conducted in USA [27][28][29], two in China [30,31], two in Germany [32,33], one in Iran [34], four in Italy [12,[35][36][37], one in Poland [25], three in Russia [26,38,39], two in Saudi Arabia [40,41], one in South Africa [42]. Among the studies two were randomized controlled trial.…”

Two studies calculated daily water intake volumes based on the volunteers' lean body weight [25,27]; one study calculated daily water intake volumes by 120 mL per 100 kcal/d [34]; one study described daily water intake by cups [30]. Sixteen studies reported the intervention as more than 1.2L of water intake, one study had unclear increased water intake [27], one study described high daily water intake as evidenced by a urine volume of at least 2L [12].…”

Only three studies described the pH of consumed water [30,34,36]. The volume and duration of water intake also varied.…”

How to cite this article: Lin Z, Lieske JC, Li Y, Jayachandran M. High water intake in preventing the risk of Uric Acid Nephrolithiasis: A systematic review and meta-analysis. AbstractBackground: Hyperuricosuria, persistently low urinary pH, and low urinary volume are the main risk factors of uric acid nephrolithiasis. Epidemiologic studies suggest that high water intake is protective against the occurrence of symptomatic kidney stone events of all types. The objective of this systematic review and meta-analysis were to evaluate the effectiveness of increased water intake to prevent symptomatic uric acid kidney stone events.Methods: A literature search was performed in the PubMed, Science Direct, Cochrane library, China National Knowledge Infrastructure (CNKI) and Wang fang data based without a beginning date restriction through November 2018. Risk factors including 24 hour urinary uric acid excretion, urinary pH, urine volume, and relative super saturation of uric acid were selected as outcomes. Statistical synthesis was conducted using Review Manager 5.3.3. The systematic review and meta-analysis was completed using random-effects model and standardized mean difference (SMD) as the effect size. Q and I2% statistic indices were applied for heterogeneity testing.Results: Seventeen studies were identifi ed for the meta-analysis. Analysis of Q and I2% statistics revealed that a high heterogeneity in 16 studies, thus, random effects model was used. Protective associations were identifi ed for high water intake individuals (SMD=0.52 L; 95% CI: 0.19, 0.84; p=0.002); a signifi cantly decreased relative super saturation of uric acid versus controls (SMD=-1.15; 95% CI: -2.00, -0.30; p=0.008). Risk factors including urinary uric acid excretion and pH were not signifi cantly related to high water intake (SMD=7.32mg/d, 95% CI: -52.27, 66.91; p=0.81), (SMD=0.14; 95% CI: -0.02, 0.31; p=0.09), respectively. Further subgroup analyses revealed that urinary uric acid excretion was signifi cantly decreased in healthy individuals (SMD=-36.23 mg/d, 95% CI: -65.14, -7.31; p=0.001) compared to stone formers (SMD=27.41 mg/d, 95% CI: -33.18, 88.01; p=0.38); urinary uric acid excretion was signifi cantly decreased in routine water intake groups (SMD=-61.49 mg/d, 95% CI: -120.74, 12.24; p=0.04) compared to mineral water intake groups (SMD=44.50 mg/d, 95% CI: -18.30, 107.29; p=0.16); urinary pH was signifi cantly higher in mineral water groups (SMD=0.13, 95% CI: 0.01, 0.46; p=0.04) compared to regular water groups (SMD=-0.00, 95% CI: -0.13, 0.13; p=0.98). Conclusion:This meta-analysis identifi ed evidence that urinary uric acid excretion, volume, pH and relative supersaturation of uric acid can be altered with high water intake intervention, reducing the risk of uric acid kidney stones.
