Research group/lab

Functional urology

We aim to optimize the clinical management of neurogenic and non-neurogenic bladder dysfunction, including urinary incontinence and retention, in paediatric and adult patients.

About our research group/lab

Our research

Research on urinary incontinence

To improve care for urinary incontinence, our research focuses on the development, testing and optimization of new therapies, such as sacral neuromodulation and neurotoxin treatment, and the development and validation of a therapy outcome prediction model.

Research on urinary retention

To improve care for urinary retention, we are developing and testing a new pacemaker for neuromodulation in close collaboration with Technical University Delft. Furthermore, we are assessing the clinical safety and efficacy of re-usable catheters.

Preclinical laboratory

Our preclinical laboratory is supportive to planned clinical studies by studying the safety and efficacy of new therapies with an emphasis on neuromodulation.

Our projects

We are an established research center of expertise for urinary incontinence and retention in children and adults.

Recent scientific achievements include:

  • Demonstration of clinical efficacy of ProACTTM, which is a minimally invasive continence balloon to treat urinary incontinence.

  • Demonstration of:

    • Clinical efficacy of intra-sphincteric botulinum toxin A injections in children with non-neurogenic bladder dysfunction.
    • Long-term efficacy of reconstructive surgery of the lower urinary tract in children.
    • Neurogenic bladder dysfunction in the early phase of paediatric multiple sclerosis.
    • Efficacy of urotherapy in children with non-neurogenic bladder dysfunction.
  • Demonstration of clinical efficacy of sacral neuromodulation for urinary incontinence

  • Development in collaboration with the Technical University Delft of a prototype high frequency pacemaker for electrostimulation of the sacral nerve.
