Detrusor function allows bladder filling with little or no change in pressure. No involuntary phasic contractions occur despite provocation. Normal voiding is achieved by a voluntary initiated continuous detrusor contraction that leads to complete bladder emptying within a normal time span, and in the absence of obstruction. For a given detrusor contraction, the magnitude of the recorded pressure rise will depend on the degree of outlet resistance (Abrams et al. 2002). |
Neurogenic detrusor overactivity |
Neurogenic detrusor overactivity |
|
|
Is a urodynamic observation in individuals with a neurological condition characterized by involuntary detrusor contractions during the filling phase which may be spontaneous or provoked (Abrams et al. 2002). |
Underactive detrusor |
Underactive detrusor |
|
|
Is defined as a contraction of reduced strength and/or duration, resulting in prolonged bladder emptying and/or a failure to achieve complete bladder emptying within a normal time span (Abrams et al. 2002). |
Acontractile detrusor |
Acontractile detrusor |
|
|
Is one that cannot be demonstrated to contract during urodynamic studies (Abrams et al. 2002). |
