Re: Diagnosis and management of recurrent urinary tract infections in non-pregnant women
In terms of "nonantibiotic options", two other preventative strategies are of proven benefit. The first is immunoactive prophylaxis; a meta-analysis by Naber et al. (1), revealed that an oral immunostimulant (OM-89) reduced the number of UTIs by an average of 39%.
The second is replacement of the glycosaminoglycan (GAG) layer in the bladder; intravesical instillation of agents such as hyaluronic acid have been shown to reduce the UTI frequency rate by up to 77% compared to placebo. (2) Such agents tend to be used when other prophylactic measures have failed.
