What Is a Recurrent Urinary Tract Infection?

Recurrent UTI Definition

Urinary tract infections (UTIs) are caused by bacteria or fungi that find their way into a person's urinary tract, including the urethra, bladder, ureters, and kidneys. Oftentimes, a doctor will correctly identify the cause of a UTI and prescribe a treatment that clears the infection on the first try. However, some patients will experience a recurrence of their UTI symptoms. In fact, up to 1 in 4 women who have had a previously diagnosed UTI will experience a recurrence within six months [1].

The clinical definition of a recurrent UTI is having two or more UTI episodes in the past six months, or three or more UTI episodes in the past year. If you are getting frequent UTI symptoms but receiving negative test results, you deserve more thorough diagnostic and clinical evaluation.

Why do people get recurrent UTIs?

There are a number of potential contributing factors as to why certain people may experience recurrent UTIs. Some of these factors include anatomy, behaviors, hormones, and underlying medical conditions. Common reasons include:

In Women

• Sexual activity, particularly with new sex partners or certain sexual practices, such as anal intercourse
• Disruption of the vaginal microbiome due to the use of contraceptives such as spermicides or diaphragms
• A decline in vaginal estrogen due to menopause
• Incomplete bladder emptying due to pelvic floor dysfunction or other issues

In Men

• Urinary retention due to an enlarged prostate
• Prostatitis, or inflammation of the prostate gland, which can harbor bacteria and trigger recurrence of UTI symptoms
• Urethral strictures or stones
• Recent urologic procedures or urologic devices, such as urinary catheters

Shared Risk Factors

• Kidney or bladder stones
• Diabetes and high blood sugar
• Dehydration and infrequent urination
• Recent antibiotic exposure, which may disrupt protective bacteria in the urinary tract

Do I need to keep getting tested if I keep getting UTIs?

While many doctors will prescribe treatment for patients to use when UTI symptoms flare in the future, it is best to continue to get tested for each instance of UTI recurrence. This is because there is no way to know for certain that your infection will be successfully treated by the drug your doctor prescribed. This practice can also contribute to the development of antibiotic resistance, which makes UTIs harder to treat for everyone.

While some recurrent UTIs can be caused by reinfection with the same pathogen, the only way to know for certain is through laboratory testing [2]. Certain diagnostic tests are becoming increasingly used over urinalysis and urine culture, which can more accurately identify which pathogen is causing the recurrent UTI as well as guide precision treatment, such as the BIOTIA-ID Urine Test.

Advanced Testing for Recurrent UTIs

For patients with recurrent UTIs, standard urine culture may miss the full picture. The BIOTIA-ID Urine Test uses next-generation sequencing (NGS) technology to identify over 40 urogenital pathogens — including bacteria, fungi, and viruses — along with antibiotic resistance markers. This level of diagnostic precision helps clinicians tailor treatment to the specific pathogen driving your recurrence, rather than relying on empiric antibiotic therapy that may not work.

How do I prevent UTI recurrence?

A variety of tangible steps can be taken to help prevent recurrent UTIs. Some of these steps include:

• Everyday habits: Staying hydrated, avoiding holding your pee, peeing after sex, and addressing constipation.
• Vaginal Estrogen: Particularly for people post-menopause, topical vaginal estrogen has been found to help support the vaginal microbiome and reduce recurrent UTIs. Topical vaginal estrogen is available in the United States by prescription only.
• Antibiotic stewardship & strategies: Available only through a prescription from your doctor, antibiotics can help prevent UTI recurrence by choosing the right antibiotic from the start. Some doctors will prescribe antibiotics for use after sex or a low-dose daily prophylaxis for a short period of time.
• Non-antibiotic strategies: There is limited, and often conflicting, research into non-antibiotic strategies for preventing recurrent UTIs. These studies often focus on cranberry products, D-mannose, and Lactobacillus probiotics. More evidence is needed to determine how successful these strategies are.

How does testing fit into prevention?

Highly accurate diagnostic testing, combined with targeted therapy, continues to be the best way to prevent UTI recurrence. Getting the right test at the right time is particularly important, as taking antibiotics can impact the ability of a test to correctly identify a pathogen. If you continue to experience recurrent UTIs, bringing a history of your UTIs to your doctor may help. On this list include:

• Date of each episode and what treatment you were prescribed
• Diagnostic testing results, including the type of test used
• Triggers you have noticed (such as getting UTI symptoms after sex)
• Other health conditions and medications
• Contraception and menopause status

The bottom line is that recurrent UTIs are manageable through prevention methods, comprehensive diagnostic testing, and targeted treatment. When in doubt about your UTI symptoms and whether you fit the criteria for recurrent UTI, talk to your doctor.
