Bladder Autonomic Dysfunction after a Parietal Stroke.

We describe a case of a 57-year-old man who, immediately after a right parietal ischemic stroke, showed urodynamically determined bladder sensory decrement during filling and an underactive detrusor during voiding, both of which were ameliorated during the course of his treatment. The lower urinary tract symptom (LUTS) occurs in stroke in up to 60% of patients, when it involves the frontal and insular cortices. In addition, LUTS does occur in parietal stroke as seen in our patient, presumably by sensory deafferentiation within the brain that is relevant to the central regulation of the micturition reflex.
