Study information

Scientific title

A comparative study between oxybutynin and botulinum toxin type A in patients with neurogenic detrusor overactivity: urodynamic response and impact of treatment on quality of life: a randomised trial

Acronym

BoNTA

Study hypothesis

Botulinum toxin type A (BoNTA) injection into the detrusor muscle will result in improvement in urodynamic parameters, such as maximum cystometric capacity (MCC), maximum detrusor pressure (Pdetmax), and bladder compliance and on quality of life after 24 weeks when compared with oral oxybutynin in patients with detrusor overactivity (DO) resulting from spinal cord injury (SCI)

Ethics approval

Ethics Board Committee Faculty of Medical Sciences of State University of Campinas (UNICAMP) approved on 24/03/2010. Ref. Number: 0098.0.146.000-10
