[Contribution of urodynamic examinations in the exploration of micturition disorders in patients with Parkinson disease].

24 men (mean age 71.2 years) with micturition disorders and parkinson disease have been studied: irritative symptoms are present in 62.5%. Urodynamics were specially usefull when obstructive symptoms (37.5%). In these cases, 3/4 had a mechanical obstruction to be treated by surgery. 3 men had a neurologic bladder and needed a pharmacological treatment. In this high risk population, urodynamics seemed to be necessary.
