Comparison of maximum voided volume and maximum bladder capacity in voiding diary, uroflowmetry and cystometrography in children with non-neurogenic lower urinary tract dysfunction.

MVV in VD and UF are comparable, but MBC in CMG is lower in children with non-neurogenic LUTD selected for invasive urodynamic studies. More attention should be paid to bladder capacity obtained from urodynamic studies in children exhibiting the characteristics identified in the subgroup analysis. We believe that evaluating bladder capacity values, especially obtained from invasive studies, in conjunction with clinical findings can prevent misdiagnosis, over investigation and overtreatment in children with non-neurogenic LUTD.
