recurrent UTIs in non pregnant women

Last edited 08/2022

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
