A cross-sectional case-control study comparing children with CP and LUTS and children with CP without LUTS will be conducted with the primary objective to investigate correlation between uroflowmetry parameters and different LUTS.~Children will be evaluated with uroflowmetry and subsequent post void residual measurement and the validated vancouver symptom score for dysfunctional elimination syndrome.
Until now, the use of invasive urodynamics with use of catheters is still the gold standard for lower urinary tract evaluation in subjects with CP. This suggests a psychological and physical impact of invasive urodynamics in subjects with CP and further demonstrates the need to avoid standard use of invasive urodynamics in children and adults with CP.~The current study will evaluate usefulness of uroflowmetry, correlation between uroflowmetry parameters and different lower urinary tract symptoms will be investigated. Secondly, results of uroflowmetry indicating possible vulnerability of the upper urinary tract will be defined.
