Lower urinary tract dysfunction is frequent in Parkinson's disease and other Parkinsonian syndromes and can cause urinary incontinence complicating a urgency-frequency syndrome or on the contrary, dysuria. These disorders are a frequent urological presenting complaint due to their impact on the patient's quality of life. Urologists must be aware of the different natural histories of diseases such as Parkinson's disease and Parkinsonian syndromes such as multisystem atrophy, which often have a severe course and are marked by resistance to neuropharmacological treatments. These various diseases can also directly induce urinary symptoms, independently of urological complications. Inversely, the development of urinary disorders, especially obstructive symptoms, in a patient with Parkinsonian syndrome may require review of the neurological diagnosis. Finally, therapeutic management is complex due to the difficulty of using pharmacological treatments, and the risk of deterioration after surgical treatment of obstructive uropathy.
