The purpose of this study is to examine how injection of botulinum toxin in the bladder affects bladder function. The trial is carried out in children born with malformation of the spinal cord and subsequent overactive bladders. The purpose of treating the bladder (with different drugs) is to prevent damage to the kidneys and renal function. The aim of this study is to compare a conventionally used drug (oxybutynin) with botulinum toxin. The hypothesis of the study is that botulinum toxin is equal to oxybutynin in the treatment of overactive bladder.

Primary Outcome Measures:
  • Bladder capacity and pressures: measures from cystometry [ Time Frame: at 4 weeks and 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Urinary continence: score from an incontinence rating scale [ Time Frame: 2 days before and 4 weeks and 6 months after ] [ Designated as safety issue: No ]
  • Constipation: score on the Bristol scale [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 30
Study Start Date: May 2005
Estimated Study Completion Date: June 2008
Estimated Primary Completion Date: March 2008 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Botulinum A toxin
    Intravesical injection. 12 IE/kg b.w.
Detailed Description:
Neurogenic bladder is often seen in children with myelomeningocele, tumors in the spinal canal, or a traumatized spinal cord. The majority of the patients have high pressure bladders which can lead to reflux and frequent infections in the urinary tract. Although children experience insufficient bladder emptying, many of them also experience urinary incontinence and have to perform clean intermittent catheterization (CIC). If no intervention is made, the children are at high risk of renal deterioration.
