Urodynamic abnormalities in neurologically normal children with micturition dysfunction.

We evaluated by video urodynamic study 60 children between 4 and 16 years old who had presented with various combinations of urinary frequency, diurnal incontinence, enuresis, voiding symptoms, recurrent urinary infections and upper tract changes. A number of seemingly distinct categories of detrusor dysfunction could be identified, which may have a bearing on logical treatment selection. In addition, abnormalities of sphincter activity were noted in 12 children. The limitations and interpretation difficulties of urodynamic studies in children are stressed.
