Recurrent urinary tract infection (UTI) is defined as two or more UTIs within 6 months or three or more within 1 year. The annual recurrence rate of UTI in women is approximately 14% to 25%. Risk factors for recurrent UTI include antimicrobial exposures, more frequent sexual activity, use of spermicidal agents or diaphragms, peri- or postmenopausal status, personal hygiene practices, urinary stasis from incomplete bladder emptying, pelvic organ prolapse, and voiding dysfunction. When women present with recurrent UTI symptoms, urinalysis and urine culture should be obtained. Management guidelines recommend empiric treatment with a first-line antibiotic based on prior culture results, then changing the antibiotic if the new culture shows resistance, or waiting for culture results before selecting an antibiotic. Longer duration of therapy does not reduce the risk of recurrent UTI. Asymptomatic bacteriuria should not be treated, except in patients who are pregnant or undergoing invasive urologic procedures. Prevention of recurrent UTI begins with behavioral modification and hygienic practices. The next step is prescription of antibiotic prophylaxis with shared decision-making. Nonantibiotic methods are also used to prevent recurrent UTI, and evidence of their effectiveness varies. These methods include use of cranberry products, Lactobacillus probiotics, vaginal estrogen, methenamine supplements.
Recurrent urinary tract infections (UTIs) are common presentations in primary care, with an annual recurrence rate of approximately 14% to 25% in women, varying by population subgroup and study design.1,2 Recurrent UTI is defined as two or more infections within 6 months or three or more within 1 year.1,3
SORT: KEY RECOMMENDATIONS FOR PRACTICE
| Clinical recommendation | Evidence rating | Comments |
|---|---|---|
| A urine culture with sensitivities should be obtained for each episode of recurrent UTI.1,8,19 | C | Consensus expert opinion and established clinical standards |
| Empiric treatment of recurrent UTI episodes is recommended with a first-line antibiotic based on prior culture results, then changing antibiotics if the new culture shows antibiotic resistance, or waiting for culture results before selecting an antibiotic.1,2,23 | C | Consensus expert opinion and established clinical standards |
| Each episode of recurrent UTI should be treated for the duration typically used in patients without a history of recurrent UTI.1 Longer therapy durations have not been shown to change the rate of recurrent UTI.36 | B | Systematic review and a retroactive noninferiority study |
| Vaginal estrogen can be used to decrease recurrent UTI in women with genitourinary syndrome of menopause. Oral estrogen is ineffective.1,27 | C | Consensus guidelines; safety established and efficacy suggested by low-quality studies |
UTI = urinary tract infection.
A = consistent, good-quality patient-oriented evidence; B = inconsistent or limited-quality patient-oriented evidence; C = consensus, disease-oriented evidence, usual practice, expert opinion, or case series. For information about the SORT evidence rating system, go to https://www.aafp.org/afpsort.
These recurrent infections lead to significant patient morbidity from symptoms, with increased health care use and antibiotic resistance concerns. Recurrent UTI is also associated with psychosocial distress, sexual dysfunction, and decreased quality of life.2 These factors underscore the need for family physicians to approach recurrent UTI management holistically, balancing effective treatment, prevention, and antimicrobial stewardship with a patient-centered approach.
