Posterior urethral valves are the commonest cause of lower urinary tract outflow obstruction in male infants with an estimated incidence of 1:5000 male infants and 1:25,000 live births. Despite treatment with fulguration of the obstructing valves, bladder function is abnormal in up to 70% of older children and adolescents. Bladder dysfunction causes morbidity e.g. urinary incontinence and has been implicated in the late deterioration of renal function in this population. A poor understanding and inappropriate management of bladder dysfunction can result in unnecessary morbidity, which can handicap a child for life. Any method that measures function or dysfunction of the lower urinary tract constitutes a urodynamics investigation. Broadly, the investigations can be classified into simple or noninvasive urodynamics and invasive urodynamics. The objective of urodynamics assessments in children is to reproduce the patient's complaints or symptoms. Video urodynamics can provide additional information that may contribute to a further understanding of the problem under investigation. Urodynamics provides a useful tool to test the efficacy of treatment as well as determine any refinements necessary to improve the outcome of such treatment.
