About this study
This is a non-interventional study that will not pose any burden for the participants. The study subjects will be examined and treated in a standard manner according to current clinical recommendations for the treatment of overactive bladder (OAB). A portion of urine samples, which are routinely collected for biochemical and culture examinations as part of the diagnostic process, will be sent for examination of the characteristics of the urinary microbiome and metabolome (UMM) before and after treatment.
Read the detailed description
Participation in the study will be offered to female patients who seek treatment for OAB symptoms themselves or are referred to centers participating in the project if a clinical diagnosis of idiopathic OAB is established in their case as part of the standard examination process.
Patients will be approached by one of the authorized team members with information about the possibility of participating in this study. If the patient is interested in participating in the study, she will give written informed consent to participate in the study. Subsequently, the inclusion and exclusion criteria for participation in the study will be verified and a standardized urine collection will be performed to examine the characteristics of UMM. At the same time, the patient will fill in standard questionnaires used to determine the severity of OAB symptoms.
To research changes in UMM during OAB treatment, patients will be divided into a group with a good treatment response (responders) and a group without a good treatment response (non-responders). The primary indicator of a good treatment effect (definition of responder) is a reduction in the number of episodes of severe urgency with or without urge incontinence over 3 days documented by a voiding diary by more than 50% compared to the state before treatment. Based on the available data, treatment success is anticipated in 60% of patients.
Subsequently, the study participants will be treated with standard drug treatment for five weeks. They will then be invited to evaluate the effect of treatment using standard symptom questionnaires. At the same time, a control standardized urine collection will be performed to examine the characteristics of UMM. The patients will then end their participation in the study and will continue their treatment according to the valid clinical recommendations for treatment.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a non-interventional study that will not pose any burden for the participants. The study subjects will be examined and treated in a standard manner according to current clinical recommendations for the treatment of overactive bladder (OAB). A portion of urine samples, which are routinely collected for biochemical and culture examinations as part of the diagnostic process, will be sent for examination of the characteristics of the urinary microbiome and metabolome (UMM) before and after treatment.
Detailed description
Participation in the study will be offered to female patients who seek treatment for OAB symptoms themselves or are referred to centers participating in the project if a clinical diagnosis of idiopathic OAB is established in their case as part of the standard examination process.
Patients will be approached by one of the authorized team members with information about the possibility of participating in this study. If the patient is interested in participating in the study, she will give written informed consent to participate in the study. Subsequently, the inclusion and exclusion criteria for participation in the study will be verified and a standardized urine collection will be performed to examine the characteristics of UMM. At the same time, the patient will fill in standard questionnaires used to determine the severity of OAB symptoms.
To research changes in UMM during OAB treatment, patients will be divided into a group with a good treatment response (responders) and a group without a good treatment response (non-responders).

Questions about this trial
What is this clinical trial studying?
An observational study of Overactive Bladder, run by University Hospital Ostrava at 4 sites in Czechia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 4 May 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in Czechia. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Jiří Hynčica (0042059737 ext. 2587, jiri.hyncica@fno.cz), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of responders to the OAB treatment (time frame: 6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06921746, which also lists 18 linked publications.
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 4 May 2025.
