[Pressure-flow urologic analysis in children: reflections after 20 years of practice].

Pressure-flow analysis in children allows optimal definition of the main urodynamic parameters of micturition and clarifies certain aspects of physiology and functional disorders. This examination has allowed urologists to establish reliable relationships between the findings of the clinical interview and clinical examination and the reality of urodynamic parameters, so that, after being widely used for more than 20 years, its indications have now become exceptional, limited to the detection of detrusor-sphincter pathophysiology and a few rare voiding disorders, poorly defined by clinical findings or imaging.
