dysfunctional voiding
Learned voiding pattern characterized by intermittent relaxation of external sphincter during voiding.
Full Definition
Dysfunctional voiding is a behavioral condition where children develop maladaptive voiding patterns, typically involving intermittent contraction of the external urethral sphincter during voiding attempts. This results in interrupted urine flow, incomplete bladder emptying, and often secondary complications such as urinary tract infections and vesicoureteral reflux. Unlike neurogenic causes, dysfunctional voiding is a learned behavior that can be addressed through biofeedback, timed voiding schedules, and pelvic floor muscle training. Uroflowmetry typically shows a staccato or interrupted flow pattern.
Usage
Usage note: Distinguish from neurogenic causes; often associated with bowel dysfunction.
