Purpose: We identify risk factors for daytime or combined urinary incontinence in children with cerebral palsy., Materials and Methods: A cross-sectional case-control study was conducted including children with cerebral palsy with or without daytime or combined urinary incontinence from the CP-Reference Center at Ghent University Hospital and 2 associated special education schools. Factors were subdivided in 3 clusters of demographic and general medical data, cerebral palsy classification, and bladder and bowel dysfunction. Data were obtained using uroflowmetry with electromyography testing, a nonvalidated questionnaire and bladder diaries. Univariate and multivariate analyses were performed for variables and clusters, respectively. A final associative logistic model including all clusters was developed., Results: The study included 34 incontinent children and 45 continent children. Daytime or combined urinary incontinence was associated with intellectual disability (OR 7.69), swallowing problems (OR 15.11), use of external aids (OR 27.50) and use of laxatives (OR 13.31). Daytime or combined urinary incontinence was positively associated with dyskinesia (OR 5.67) or combined spasticity and dystonia (OR 4.78), bilateral involvement (OR 4.25), Gross Motor Function Classification System level IV (OR 10.63) and V (OR 34.00), and severe impairment in manual (OR 24.27) or communication skills (OR 14.38). Lower maximum voided volume (OR 0.97) and oral fluid intake (OR 0.96) influenced daytime or combined urinary incontinence negatively. Pathological uroflow curves were not significantly associated with incontinence. The final model defined functional impairment, intellectual disability and oral fluid intake as predictive factors for daytime or combined urinary incontinence., Conclusions: Risk analysis revealed functional impairment, intellectual disability and fluid intake as important factors influencing continence in a child with cerebral palsy., (Copyright © 2017 American Urological Association Education and Research, Inc.

Aims: To systematically review the scientific literature addressing lower urinary tract symptoms (LUTS) and urodynamic findings in adults and children with Cerebral Palsy (CP). Prognostic factors were also investigated., Methods: A systematic research was conducted on the electronic databases PubMed, Web of Science, and CINAHL. Only full text clinical trials which examined the prevalence of LUTS or urodynamic findings in children or adults with CP were eligible. LUTS and urodynamic findings, defined by the International Children's Continence Society, were extracted from the included studies. Pooled average of extracted data was calculated. Studies were scored on methodological and reporting quality using the Dutch Cochrane Checklist, EBRO guidelines, and the Strengthening the Reporting of Observational Studies in Epidemiology Statement (STROBE) checklist., Results: Twenty-seven studies fulfilled selection criteria. Methodological and reporting quality were moderate to low. An average of 55.5% of subjects with CP experience one or more LUTS. Storage symptoms are more common than voiding symptoms due to the high prevalence of neurogenic detrusor overactivity. Patients with voiding symptoms and pelvic floor overactivity are more prone to progress to upper urinary tract dysfunction in adult life. Urodynamic evaluation can direct management. Negative prognostic factors are the spastic subtype with quadriplegic distribution, moderate to severe functional impairment (GMFCS III or higher) and severe cognitive impairment., Conclusion: The significant prevalence of LUTS, risk for deterioration, and the impact of urinary tract symptoms on quality of life and health status warrants the need for evaluation and treatment in further research.
