recurrent UTI in non pregnant women (prophylactic measures)

Last edited 08/2022 and last reviewed 10/2023

Over 90% of recurrences are episodes of exogenous reinfection and not due to a persistent focus of infection.

Factors that are sometimes associated with recurrent infections:

• anatomical or functional abnormality of the urinary tract
• use of diaphragms and spermicides - may induce vaginal colonization by E.coli
• genetic susceptibility - patients do not secrete blood-group antigens
