Recurrent Urinary Tract Infections and the Microbiome

May 18, 2024 updated by: Laura Martin, University of Miami

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.

Design Details

Cohorts and Interventions

Group / Cohort
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.
