Intravesical Instillation of Oxybutynin Hydrochloride for Detrusor Hyper‐reflexia

Abstract
Summary The effect of intravesical oxybutynin hydrochloride on detrusor behaviour was studied in 15 patients with urinary incontinence due to detrusor hyper‐reflexia by ambulatory bladder monitoring. Twelve patients had a reduction in the frequency and amplitude of hyper‐reflexic contractions and incontinence episodes following oxybutynin administration. Intravesical oxybutynin may have a role in the management of patients on intermittent self‐catheterisation with detrusor hyper‐reflexia who cannot tolerate the side effects of anticholinergic agents, including oxybutynin.
