OnabotulinumtoxinA for Idiopathic Overactive Bladder, Reviewing the Procedure—A Survey of Practice Techniques in Australia and New Zealand

ABSTRACT Idiopathic overactive bladder (iOAB) significantly negatively affects patients' quality of life. Intradetrusor OnabotulinumtoxinA (BTN/A) is an effective treatment for refractory iOAB, though optimal procedural techniques remain unclear. This study aims to evaluate current BTN/A practices for iOAB in Australia and New Zealand, focusing on trigonal injection, number of injection sites and anaesthetic modality in BTN/A‐naïve female patients. A survey was conducted among specialists, urologists and gynacologists performing BTN/A for iOAB. Variance in the responses to this survey highlights the need for clear guidance and consensus for specialists on the number and location of injections for BTN/A for iOAB patients. Optimisation of procedural techniques could improve outcomes and tolerability for BTN/A injection for iOAB patients and inform further research and guidelines.
