OnabotulinumtoxinA in OAB: Optimizing Persistence With Fewer Sites

OAB is a chronic, potentially debilitating condition affecting a substantial proportion of patients in urologic practice, and effective long-term management depends on systematic escalation from behavioral modification through pharmacotherapy to third-line procedural options—including onabotulinumtoxinA (Botox)—when treatment objectives are not met.

In more than 1000 onabotulinumtoxinA (Botox) treatments using a reduced-site protocol, Steven Bernstein, MD, observed a UTI rate of approximately 4.9% per treatment, a single clinically significant post-procedural bleed (early in experience with 20-site injection), and only 1 patient advised to undergo post-procedural catheterization—findings that support a streamlined, symptom-guided approach to complication management.

In this video, Aleece Fosnight, MSPAS, PA-C, reviews the evidence and practical application of behavioral interventions and pharmacologic therapy for OAB, including the clinical and safety rationale for leading with beta-3 agonists over anticholinergics, and outlines how she frames the transition to minimally invasive therapy for patients who have not responded to prior treatments.
