There is a growing appreciation for the importance of vaginal flora in the pathogenesis and prevention of urinary tract infections. The survival of uropathogens in the vagina among the wide range of competing flora, and the emergence of these organisms to infect the bladder is not well understood. However, the ability of antimicrobial agents and spermicide to disrupt the flora and make a patient more susceptible to bladder and vaginal infection has been recently recognized. Attempts to restore a protective flora through instillation with carefully selected Lactobacillus strains does appear to have clinical potential. Alternative methods that utilize immunization have also shown some promise in vivo, but their mechanisms of action, safety, and effectiveness will require more documentation.
