This systematic review and meta-analysis found that cranberry (Vaccinium spp.) significantly reduced the risk of recurrent urinary tract infections in otherwise healthy women, supporting its use for UTI prevention.
This review of the clinical use and mechanisms of cranberry (Vaccinium macrocarpon) concludes that it is an interesting option for preventing recurrent urinary tract infections in women, alongside other health benefits.
Cranberry ( Vaccinium macrocarpon ) is a distinctive source of polyphenols as flavonoids and phenolic acids that has been described to display beneficial effects against urinary tract infections (UTIs), the second most common type of infections worldwide. UTIs can lead to significant morbidity, especially in healthy females due to high rates of recurrence and antibiotic resistance. Strategies and therapeutic alternatives to antibiotics for prophylaxis and treatment against UTIs are continuously being sought after. Different to cranberry, which have been widely recommended in traditional medicine for UTIs prophylaxis, probiotics have emerged as a new alternative to the use of antibiotics against these infections and are the subject of new research in this area. Besides uropathogenic Escherichia coli (UPEC), the most common bacteria causing uncomplicated UTIs, other etiological agents, such as Klebsiella pneumoniae or Gram-positive bacteria of Enterococcus and Staphylococcus genera, seem to be more widespread than previously appreciated. Considerable current effort is also devoted to the still-unraveled mechanisms that are behind the UTI-protective effects of cranberry, probiotics and their new combined formulations. All these current topics in the understanding of the protective effects of cranberry against UTIs are reviewed in this paper. Further progresses expected in the coming years in these fields are also discussed.

Mechanistic basis
This use is associated with the plant's urinary antiseptic action. Further evidence for that pharmacology:
This Cochrane review of 50 trials (8857 participants) found that cranberry products, whose proanthocyanidins inhibit adherence of p-fimbriated Escherichia coli to the bladder, reduce the risk of symptomatic urinary tract infections in women with recurrent UTIs, in children and in people susceptible to UTIs following interventions.
This review of clinical studies of cranberry (Vaccinium macrocarpon) consumption against urinary tract infections summarises the evidence that cranberry, via E. coli anti-adhesion, can help prevent UTIs, especially in women with recurrent infections.
This review concludes that cranberry (Vaccinium) products exert a dose-dependent inhibition of E. coli adherence to the urinary tract and can help prevent urinary tract infections when an adequate proanthocyanidin dose is provided.
