Brain Activity During Bladder Filling: Pilot Study of an fMRI Protocol
A study testing invasive urodynamic evaluation and functional magnetic resonance imaging during bladder filling in people with fMRI Research, run by University Hospital, Ghent at 1 site in Belgium.
Trial summary
Urinary incontinence is the most frequently observed lower urinary tract symptom (LUTS) in children with cerebral palsy (CP) (Samijn et al., 2016). Higher brain centers responsible for bladder function may be related to the presence of incontinence. Read more about this study

About this study
Official title: Pilot Study: Apllicability of an fMRI Protocol for Incontinence Research
Urinary incontinence is the most frequently observed lower urinary tract symptom (LUTS) in children with cerebral palsy (CP) (Samijn et al., 2016).
Higher brain centers responsible for bladder function may be related to the presence of incontinence.
The current pilot study is the first study of a research project focusing on correlations between brain damage and incontinence.
Read the detailed description
Urinary incontinence is the most frequently observed lower urinary tract symptom (LUTS) in children with cerebral palsy (CP) (Samijn et al., 2016). Being more or completely dry could improve the quality of life and health status of the child and the social environment.
Higher brain centers responsible for bladder function may be related to the presence of incontinence. These higher brain centers could be correlated to the brain damage seen in children with CP.
The current pilot study is the first study of a research project focusing on correlations between brain damage and incontinence. The study wants to validate if the defined fMRI paradigm can provide correct information concerning brain activity during bladder filling, to ensure usable results and comply with ethical demands for testing in children, the protocol will be tested and results validated during the pilot study with healthy adults. During the fMRI study, the bladder will be filled until FSF and NDV. Functional MRI-data will be obtained during the filling and emptying phase of the bladder on both volumes

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
invasive urodynamic evaluationDiagnostic test
Also called UDO
Invasive urodynamic evaluation to define maximum cystometric capacity. By means of catheterisation the bladder gets filled and volumes en pressures are measured.
functional magnetic resonance imaging during bladder fillingDiagnostic test
Also called fMRI
Functional MRI is used to capture brain activity during tasks. The task in the current study is bladder infusion and withdrawal by means of the INFSYS-2 infusion/withdrawal pump (Leitner et al. 2017)
| Study group | Role | What they receive |
|---|---|---|
| Complete evaluation UDO and fMRI | Experimental | Evaluation including both urodynamic evaluation and functional MRI testing Receives: Diagnostic Test: invasive urodynamic evaluation; Diagnostic Test: functional magnetic resonance imaging during bladder filling |
What is being measured
The primary outcome is the main question the study is designed to answer.
Activated brain regions demonstrating brain activity
fMRI brain imaging data will be analyzed using FMRIB Software Library v6.0 (FSL).
Measured: through study completion, an average of 6 weeks

What does the primary outcome measure?
Activated brain regions demonstrating brain activity (time frame: through study completion, an average of 6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jun 2024; AzTrials last refreshed its copy on 6 Nov 2026.
