For women who experience recurrent urinary tract infections, the cycle can become frustratingly familiar: symptoms appear, antibiotics are prescribed, things improve temporarily, and then the burning, urgency, or discomfort comes back. But what if some of those recurring symptoms aren’t actually being caused by an infection?
A 2026 study published in The Journal of Sexual Medicine suggests that, for many women referred for recurrent UTIs, the problem may extend well beyond the bladder. Researchers reviewed the medical records of 253 women who met the criteria for recurrent UTIs and continued to experience urogenital symptoms despite having at least two negative urine cultures.
What they found was striking. Just 15% showed evidence of problems limited to the bladder or urinary tract. The other 85% had signs of hormonally driven inflammation of the vulvar region, while 75% had pelvic floor dysfunction. These conditions can produce symptoms that closely resemble a UTI, including burning, urgency, frequency, and pelvic discomfort, but may require a very different approach.
Dr. Maria Uloko, a board-certified urologist and one of the study’s authors, described the problem in an interview with NPR: “As urologists, we do a pretty good job of the urinary part of the evaluation – the bladder, ureters, and kidneys,” but “where we fall short is the genital part, and that requires a much broader understanding of the pelvic ecosystem as a whole – the hormonal environment, vulvar tissue, and pelvic floor musculature, all influencing each other and all capable of producing symptoms that look exactly like a UTI.”
The overdiagnosis problem behind recurrent UTIs
As many as 65% of UTI diagnoses in women may be inaccurate, according to a 2024 study published in Neurourology and Urodynamics. Patients were frequently diagnosed and treated for UTIs despite not meeting diagnostic criteria, and this pattern of overdiagnosis contributes to overtreatment and worsening antibiotic resistance, particularly in acute care settings.
The scale of unnecessary prescribing in older women is especially pronounced. A 2024 study published in the International Urogynecology Journal found that 41% of antibiotic prescriptions across 454 episodes in 175 older female patients with recurrent UTI were unnecessary. The most common scenario in which an unnecessary antibiotic was prescribed was the absence of documented UTI-specific symptoms – women were receiving antibiotics for infections that had not been confirmed and, in many cases, for symptoms that were not UTI-specific to begin with.
The AUA’s 2025 guideline discourages prescribing antibiotics based on patient symptoms without microbiological evaluation, identifying this as a common cause of recurrent UTI overdiagnosis. The problem is partly structural. When a patient presents with burning and urgency, most clinicians order a urinalysis – a test that detects inflammation in the urine, not bacteria. Confirming a bacterial infection requires culturing that urine, which takes time. Because patients are in discomfort, antibiotics often get started before the culture result returns. If symptoms ease, the diagnosis is reinforced – but symptoms from inflammation or pelvic floor dysfunction can also resolve on their own, leaving a misdiagnosis invisible.
Contaminated urine samples, gathered without careful midstream technique, can produce false-positive culture results from skin bacteria rather than from a true infection. The annual recurrence rate of UTI in women is approximately 14% to 25%, according to the American Academy of Family Physicians’ 2026 clinical review.
When the problem is hormones, not bacteria
Dr. Lindsey Burnett, a urogynecologist and assistant professor at the University of California, San Diego, co-authored the Journal of Sexual Medicine study with Uloko. Lower urinary tract symptoms that look and feel like a UTI can be caused by a loss of hormones to the vulvar tissue, producing inflammation – a condition called hormonally mediated vestibulodynia – which can occur during breastfeeding and menopause.
Oral contraceptives are also implicated. A study in the American Journal of Epidemiology found that the relative risk of vulvar vestibulitis was 6.6 times higher in ever-users of oral birth control compared with never-users. Separate research published in the Journal of Sexual Medicine found that combined oral contraceptives increase the relative risk of developing pain in the vulvar vestibule by four- to ninefold. Both effects stem from the hormonal suppression these medications produce in vulvar tissue – tissue that shares nerve pathways and proximity with the urethra.
Other medications linked to the same pattern include isotretinoin (sold as Accutane) for acne, aromatase inhibitors used in breast cancer treatment, and selective estrogen receptor modulators. These drugs reduce androgen and estrogen activity in vulvar tissue, triggering inflammation that generates symptoms clinically indistinguishable from a urinary tract infection.
Pelvic floor dysfunction, present in three-quarters of the women in Uloko’s study, adds a mechanical dimension to the problem. When those muscles are too tight – a state called hypertonia – they can generate urinary urgency, frequency, and burning. In women with hormonally driven vulvar inflammation, pelvic floor tightening can develop as a secondary response, compounding the symptoms.
The menopause connection most clinicians miss
Postmenopausal women face a particularly concentrated version of this problem. Genitourinary syndrome of menopause (GSM) causes the tissues of the vagina, vulva, urethra, and bladder to become thinner, drier, less elastic, and more fragile as estrogen falls after menopause, according to Johns Hopkins Medicine. Common symptoms include vaginal dryness, itching, pain during sex, urinary urgency, and recurrent urinary tract infections.
GSM is a chronic, progressive hypoestrogenic condition affecting vulvovaginal, urinary, and sexual health. Inflamed, atrophied tissue around the urethra generates urgency and burning – symptoms that get cataloged as UTI symptoms; antibiotics get prescribed, and the underlying cause – estrogen loss – goes unaddressed.
Hormone changes during menopause may also shift the bacterial landscape inside the urinary tract. When estrogen drops, protective bacteria decline, creating conditions that genuinely favor bacterial infections. Women with GSM-related symptoms may not have a bacterial UTI, but the same hormonal environment that causes their symptoms can eventually make real infections more likely – making accurate diagnosis more important, not less.
Negative urine cultures in women over 40 with recurring UTI-like symptoms warrant evaluation for GSM, pelvic floor dysfunction, and hormonally mediated vestibulodynia – each of which produces symptoms indistinguishable from a bacterial infection.
Why the standard diagnostic process falls short
The urinalysis, the first test most clinicians reach for, detects white blood cells in the urine – a marker of inflammation. Inflammation has many causes beyond bacterial infection. Atrophic vulvar tissue, pelvic floor tension, and chemical irritants can all produce enough urinary inflammation to trigger a positive urinalysis without any bacterial infection present.
The urine culture – the test that actually identifies bacteria and confirms infection – takes 24 to 72 hours. In practice, patients are rarely willing to wait that long in discomfort, and clinicians frequently start antibiotics in the interim. In 11% of antibiotic episodes in one study, antibiotics were prescribed without any documented UTI-specific symptom and without any testing at all.
Beyond inadequate testing, a knowledge gap exists even among specialists. Doctors are trained to treat classic UTI symptoms as a UTI until proven otherwise, and medical education around vulvar health – particularly how vulvar tissue interacts with urinary function – remains underdeveloped. Patients whose symptoms don’t respond to the first antibiotic often receive a second course, then a third, then a referral for “recurrent UTIs,” never hearing that the problem may not be in their bladder at all.

Treatment that matches the actual cause
The appropriate treatment depends on what is driving the symptoms. For women with GSM-related symptoms, the AUA’s 2025 Genitourinary Syndrome of Menopause guideline recommends local low-dose vaginal estrogen to reduce the risk of future urinary tract infections. Low-dose vaginal estrogens, available in creams, tablets, inserts, and rings, act locally to replenish hormones with minimal systemic absorption.
Symptom relief and UTI reduction from vaginal estrogen can take up to 12 weeks. Vaginal DHEA and oral ospemifene are FDA-approved alternatives for the management of GSM for women who cannot or prefer not to use estrogen.
For pelvic floor dysfunction, pelvic floor physical therapy is the primary intervention. A trained pelvic floor therapist can assess whether the muscles are too tight and use manual techniques and targeted exercises to restore normal muscle tone. This differs from standard Kegel exercises, which are designed to strengthen weak muscles and can worsen symptoms in women whose pelvic floor is already hypertonic.
For women whose symptoms are linked to oral contraceptives or other hormone-altering medications, switching to a non-hormonal method or discussing medication alternatives with a prescriber may reduce vulvar inflammation over time. This requires weighing individual circumstances with a clinician who understands the hormonal-vulvar connection.
The 2025 AUA guideline on recurrent UTIs explicitly discourages prescribing antibiotics based on symptoms alone, directing clinicians toward patient-centered care and non-antibiotic options where appropriate.
What to do now
For women facing overdiagnosis of recurrent UTIs, the first practical step is requesting a urine culture before accepting an antibiotic prescription. A culture confirms whether bacteria are present, which species they are, and which antibiotics will work against them. If the culture returns negative, that result warrants a conversation about alternative causes rather than a different antibiotic.
A thorough evaluation should include questions about hormonal status, current medications (including oral contraceptives, acne treatments, and any cancer-related hormone therapies), and symptoms in the vulvar or vaginal area – not just the bladder. Burning or urgency accompanied by vulvar irritation, dryness, or pain during sex points toward hormonally driven causes rather than bacterial ones.
Requesting a referral to a urogynecologist or a urologist with specific experience in women’s pelvic health is reasonable for any woman who has had three or more antibiotic courses in a year without lasting resolution. E. coli causes 70–95% of both upper and lower UTIs and does require targeted antibiotic treatment when confirmed. Each unnecessary course of antibiotics fails to resolve the real cause and contributes to antibiotic resistance.
