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

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.
