[Vesico-sphincteric dysfunction in children. Apropos of 85 cases, neurologic contexts excluded].

The authors have evaluated the dysfonctional patterns of low urological tract in 85 children between 3 and 14 years old, without urinary malformations or neurologic disorders. The clinic, radiologic, endoscopic and urodynamic studies identified three most common voiding patterns abnormalities: --non inhibited bladder, --detrusor-external sphincter dyssynergia during voiding, --bladder neck contracture.
