Plain English Summary

Background and study aims
Lower urinary tract dysfunction (LUTD) in childhood might affect both lower urinary tract function and psychosocial wellbeing later on in life. The long-term outcome and prognosis are largely unknown.
The aim of this study is to evaluate the long-term functional and psychosocial outcome of adolescents and young adults treated for childhood LUTD and compare these outcomes to healthy age-related controls and treatment outcome in the past.

Who can participate?
Former patients treated for childhood LUTD, currently aged 16-26 years, and a healthy control group

What does the study involve?
Both former patients and controls complete a four-part paper survey composed of validated questionnaires measuring LUTD, general- and disease-specific quality of life and mental health.

What are the possible benefits and risks of participating?
There are no benefits or risks involved in participation.

Where is the study run from?
January 2018 to June 2020

When is the study starting and how long is it expected to run for?
Radboud University Medical Center, Amalia's Children's Hospital (Netherlands)

Who is funding the study?
Investigator initiated and funded

Who is the main contact?

Long term psychosocial and functional outcome of former patients treated for childhood lower urinary tract dysfunction


After informed consent, a four-part paper survey is sent including questions about demographics, psychiatric co-morbidity, LUTS (Lower Urinary Tract Symptoms), general and disease-specific quality of life (DSQOL) and mental health. A healthy age-related control group receive the same survey. Validated existing questionnaires are used: the overactive bladder questionnaire to assess LUTS and DSQOL, the pediatric Quality of life Inventory (PedsQol) or Short Form-36 (SF-36) to determine quality of life and the Hospital and Depression Scale (HADS) to assess mental health.

The mean follow-up time for former patients is 8.8 +/- 4.4 years after treatment in childhood. The OAB-q score for controls is the score at the time of completing the survey

Intervention type



Drug names

Primary outcome measure

Overall number of lower urinary tract symptoms measured using the validated Overactive Bladder Questionnaire (OAB-q) score at a single timepoint

Secondary outcome measures

Measured at a single timepoint:
1. Type of lower urinary tract symptoms measured using the validated Overactive Bladder Questionnaire (OAB-q)
2. General quality of life measured using Pediatric Quality of life Inventory (PedsQol) for subjects <18 years of age and Short Form-36 Health Survey (SF-36) for subjects ≥18 years of age
3. Disease-specific quality of life measured using the OAB-q
4. Mental health outcomes measured using the validated Hospital and Depression Scale (HADS)
5. Prognostic factors for lower urinary tract symptoms later in life related to treatment outcome in the past measured using a multivariable backward regression model at time of data analysis

Planned publication in a high-impact peer-reviewed journal.

IPD sharing statement
The researchers use CASTOR for data management, furthermore, studies are registered in PANAMA, this study is registered under number 108187. For analyses, data are loaded in SPSS as CASTOR is not able to do that. The data stored are the filled-in 4-part paper surveys and informed consents of all subjects. All data are anonymised and only the principal investigator has access to the actual identification of subjects.
