[Functional tests for true urinary incontinence in women (author's transl)].

Urinary incontinence is looked at from a functional point of view. It occurs when there is lack of equilibrium between the resistance of the sphincters and the expulsive force of the bladder. The classical features given in the history and in a clinical examination can only suggest an incomplete evaluation of the problem and this is sometimes wrong in respect to the dynamic control of micturition. The traps are briefly reviewed. Functional tests allow objective analysis of the behaviour of the bladder and its sphincters. They are the subject of this study (combined radio-urodynamic tests).
