Changes in the Urinary Microbiome and Metabolome During Treatment of the Overactive Bladder in Female Patients

NCT06921746 | Recruiting

• 1 other identifier: MicrOAB-001
• Study Type: observational
• Target: 80
• Locations: 1 country
• Sites: 4

Brief Summary

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.
