bladder neck dysfunction
Abnormal function of the bladder neck leading to incomplete bladder emptying or incontinence.
Full Definition
Bladder neck dysfunction refers to abnormal function of the smooth muscle at the bladder neck, which can manifest as either inadequate opening during voiding (causing outlet obstruction) or inadequate closure during filling (causing incontinence). In pediatric patients, this condition may be primary or secondary to neurological conditions. Diagnosis typically requires urodynamic studies to differentiate from other causes of voiding dysfunction.
Usage
Usage note: Distinguish between obstructive and incompetent types; requires urodynamic confirmation for diagnosis.
