Urodynamics in normal infants and children.

摘要: Urodynamic examination yields invaluable information about lower urinary tract function in infants and children the following clinical situations: Daytime incontinence, suspected infravesical obstruction, overt or neurogenic bladder dysfunction, vesico-ureteral reflux with upper dilatation chronic recurrent bacteriuria. A normal development of during first 5 years life means that detrusor contractility will be successively more inhibited; furthermore, child become aware filling able to postpone initiate micturition. disturbed delayed may well most important cause dysfunctional states later life. Most urodynamic variables are age-dependent. Normal capacity can fairly assessed by: Bladder ml = 30 + (age x 30). maximum flow micturition (in ml/s) should approximately equal square root voided volume ml). The range (+/- 2SD) is given by value thus obtained +/- 7 ml/s. Intravesical pressure girls than boys, older children, but otherwise it does not vary age. tense apprehensive produce reliable data. This is, no doubt, source error when examining children. It strongly emphasized, therefore, has performed a kind, understanding relaxed atmosphere.
