INTRODUCTION - Uroflowmetry with electromyography (uroflow-EMG) is commonly used for evaluation of lower urinary tract (LUT) function in children. Diagnostic criteria based largely on uroflow-EMG findings have previously been proposed for several conditions collectively termed non-neurogenic voiding disorders (NNVDs). These include dysfunctional voiding (DV), idiopathic detrusor overactivity disorder (IDOD), detrusor underutilization disorder (DUD), and primary bladder neck dysfunction (PBND). It is unknown whether practitioners with varying levels of training and experience can apply the diagnostic criteria for these conditions with a high level of consistency.
