Evaluating antibiotic use before onabotulinumtoxinA injections for overactive bladder

Optimizing Antibiotic Use in Treatment of Overactive Bladder: Evaluating the Need for Prophylactic Antibiotics Prior to OnabotulinumtoxinA Injection in Patients Without Urinary Tract Infection

Not applicable Interventional Benaroya Research Institute · NCT04754737

This study is testing if giving antibiotics before onabotulinumtoxinA injections helps or is needed for adults with overactive bladder who haven't found relief from other treatments.

What this trial studies

This study investigates the necessity of prophylactic antibiotics prior to intradetrusor injections of onabotulinumtoxinA in patients with overactive bladder (OAB). It aims to optimize antibiotic usage by comparing outcomes between patients receiving antibiotics and those who do not. The study includes adults diagnosed with OAB who have not responded to standard therapies and ensures participants are not symptomatic for urinary tract infections (UTIs) at the time of injection. By addressing the appropriateness of antibiotic use, the study seeks to reduce unnecessary complications associated with antibiotic therapy.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older diagnosed with OAB who have failed first and second line therapies.

Not a fit: Patients who have recently used antibiotics or are symptomatic for UTIs will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective management of antibiotic use, reducing the risk of complications and antibiotic resistance in patients undergoing treatment for OAB.

How similar studies have performed: While studies have shown success in antibiotic stewardship in other surgical contexts, this specific approach to OAB treatment is novel and untested.
