About our research group/lab
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.
Our preclinical laboratory is supportive to planned clinical studies by studying the safety and efficacy of new therapies with an emphasis on neuromodulation.
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.
- 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.
