Recurrent Urinary Tract Infections and the Microbiome
An observational study of Recurrent Urinary Tract Infection, run by University of Miami at 2 sites in United States.
Trial summary
The primary objective is to determine if polymerase chain reaction (PCR) (UTIP™) is more sensitive in identifying urinary tract infections (UTI's) than standard urine cultures. Read more about this study

About this study
Official title: Is PCR Amplification More Sensitive Than Urine Cultures in Diagnosing Urinary Tract Infections in Patients With Recurrent Bladder Infections?
The primary objective is to determine if polymerase chain reaction (PCR) (UTIP™) is more sensitive in identifying urinary tract infections (UTI's) than standard urine cultures.
- Conditions
- Recurrent Urinary Tract Infection
- Medical subject headings
- Urinary Tract Infections
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Female participants with recurrent urinary tract infections (RUTI). | Patients with RUTIs (Group A) will provide two urine samples. One urine sample is a clean catch and the other is a catheterized specimen. Both will be sent for analysis. A perineal swab will also be collect and analyzed for each patient. | |
| Female control patients without RUTIs | Patients without RUTIs (Group B) will provide two urine samples. One urine sample is a clean catch and the other is a catheterized specimen. Both will be sent for analysis. A perineal swab will also be collect and analyzed for each patient. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of uropathogens
The proportion of uropathogens found on PCR versus urine culture from urine samples.
Measured: Day 1
Proportion of patients negative for repeat testing
The proportion of negative patient on repeat testing of urine samples.
Measured: Up to 4 weeks

The record says: stopped early, as of the sponsor's last update on 21 May 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: No longer with institution). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of uropathogens (time frame: Day 1). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 May 2024; AzTrials last refreshed its copy on 1 Nov 2026.
