Name:: Bladder function detrusor function type
Steward:: NINDS
Definition:: Type of magnitude of the detrusor function on the participant/subject
Registration Status:: Qualified

Value	Code Name	Code Description
Normal	Normal	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).
Unknown	Unknown	Is used if the observation regarding detrusor function is not available.
