Prevalence of urinary incontinence after brain injury

There is little reported in the literature describing the prevalence of voiding dysfunction after brain injury. A prospective study was conducted, 54 consecutive admissions to our brain injury unit from September 1992 through January 1993 were screened for signs and symptoms of voiding dysfunction. Signs and symptoms were noted in 24 patients (44.4%). There was no statistically significant difference in symptom prevalence based on age, sex, hemisphere (right or left) injured, or presence or absence of a frontal lobe injury. Those functioning at a lower cognitive level (Rancho Los Amigos Scale VI or less) had a higher symptom prevalence than the VII-VIII group (p = 0.004, Chi Square Test).
