The role of probiotics on the urinary tract
Micro-organism inhabit many sites of the body, including the urinary tract and play a role in maintaining urinary health. Micro-organisms impact on urinary health is likely to be secondary their metabolic activity.
Recent studies of the urinary microbiota have identified remarkable differences between healthy populations and those with urological disease, including recurrent urinary tract infections, kidney stones, interstitial cystitis and voiding dysfunction.
A recent meta-analysis (a method for systematically combining pertinent studies to develop a single conclusion with greater statistical power) identified Lactobacillus rhamnosus GR-1 as one of the most effective organisms in preventing recurrent urinary infections. While other studies have shown Lactobacillus reuteri to be effective in reducing adherence of pathogenic E coli to the intestinal tract. E coli is the most common cause of urinary tract infections.
