Lower Urinary Tract Dysfunction in Neurological Patients

      The lower urinary tract (LUT, bladder and urethra) has two roles: storage of urine and emptying at appropriate times. The optimal and coordinated activity of the LUT is subject to a complex neural control which involves all levels of the nervous system, from cortex to peripheral innervation. The complexity of the neural control of LUT explains the high prevalence of urinary disturbances in neurologic disease. Information obtained from history taking and supplemented by use of a bladder diary forms the cornerstone of evaluation. Ultrasonography is used to assess the degree of incomplete bladder emptying, and for assessing the upper tracts. Urodynamic tests, with or without simultaneous fluoroscopic monitoring, assess detrusor and bladder outlet function and give fundamental information about detrusor pressure and thus the risk factor for upper tract damage.
