Increased fluid intake to prevent urinary tract infections: systematic review and meta-analysis
Review of 7 RCTs concludes increased fluid intake reduced the overall rate of all recurrent UTIs (rate ratio [RR] 0.46, 95% CI 0.40 to 0.54, P<0.001); however, further research is warranted to establish the optimal volume and type of fluid.
