The Inﬂuence of Increased Fluid Intake in the Prevention of Urinary Stone Formation: a Systematic Review
ABSTRACT: to assess whether the volume of ﬂuid intake inﬂuence the prevention of urinary stone formation. Methods: a systematic review from MEDLINE Electronic database was conducted. All of the controlled trial (RCT), case-control, and cohort studies written in English language were included in the study. Data analysis was performed to the design of the study, volume of ﬂuid intake (higher volume as experimental group and lower volume as control group), and risk of stone formation. All of the included studies were appraised using the Oxford Center for Evidence-based Medicine appraisal tool for therapy (Randomized Controlled Trial) and level of evidence. Results: our systematic review included fve studies (1 RCT and case-control study in patients with history of urolithiasis, and 3 prospective cohorts in patients without history of urolithiasis). Three studies increased ﬂuid intake to 2.5 Liters/day and one study to 2 Liters/day, while one other study used the urine production target of 2 Liters/day. All of these studies showed that increased ﬂuid intake per day could decrease the risk of both primary and secondary stone formation. Conclusion: stronger evidence are still needed to conclude that increasing ﬂuid intake could be utilized as a strategy to prevent primary urolithiasis because of the lack of data from the clinical trials supporting it. However, to prevent the recurrence of urolithiasis, increasing ﬂuid intake could be recommended with the urine volume target of more than 2,000 mL/day.
