Risk factors
Risk factors associated with UTIs include:
- bladder outlet obstruction
- anatomic functional abnormalities of the urinary tract with incomplete bladder emptying (e.g., neurogenic bladder, vesicoureteric reflux)
- previous urinary tract surgery
- recent procedures: cystoscopy, catheterization, or transrectal prostate biopsy (1)
- immunocompromised state
- institutional care
- age >65 years (1)
- homosexuality - exposure to E.coli through anal intercourse
- lack of circumcision - associated with an enhanced colonization of the prepuce and glans by E.coli
- sexual partner with vaginal colonization by uropathogens (2)
- CD4 lymphocyte count of less than 200 per cubic millimetre
- general predisposing factors (see menu)
Intercourse with an infected partner, anal intercourse and lack of circumcision have been associated with acute uncomplicated UTI’s (2).
