Intradetrusor Injections of Botulinum Toxin A in Adults with Spinal Dysraphism

International audience; Purpose:The aim of the current study was to determine the outcomes of botulinum toxin A intradetrusor injections in adult patients with spina bifida.Materials and methods:All patients with spinal dysraphism who underwent intradetrusor injections of botulinum toxin A from 2002 to 2016 at a total of 14 centers were retrospectively included in analysis. The primary end point was the global success of injections, defined subjectively as the combination of urgency, urinary incontinence and detrusor overactivity/low bladder compliance resolution. Univariate and multivariate analysis was performed to seek predictors of global success.Results:A total of 125 patients were included in study. The global success rate of the first injection was 62.3% with resolution of urinary incontinence in 73.5% of patients. All urodynamic parameters had improved significantly by 6 to 8 weeks compared to baseline, including maximum detrusor pressure (–12 cm H 2O, p
