What is dysfunctional voiding?
Dysfunctional voiding may be due to a neurogenic bladder or the so-called pediatric unstable bladder. The bladder may show variable degrees of wall thickening, trabeculation, and alteration in contour and storage capacity.
Bladder-sphincter dyssynergia may be indicated by the presence of a dilated posterior urethra caused by the external sphincter failing to relax as the bladder neck opens. This condition often leads to high-pressure voiding, incomplete emptying, and urine retention.
