Videourodynamic assessment of diurnal urinary incontinence.

Persistent daytime incontinence is a fairly uncommon but important problem. Videourodynamic studies were carried out in 215 children presenting with this problem in whom there were no neurological signs and who had not responded to simple measures. Over 90% of symptomatic children were shown to have an abnormality, of which over half had detrusor instability and a fifth had the wide bladder neck anomaly. We consider that it is important that these children are fully assessed as many can be helped.
