| When detrusor external sphincter dyssynergia (DESD) occurs, there is a lack of coordination between the bladder and the external sphincter muscle, which is the muscle that controls the emptying of the bladder. Instead, when the detrusor muscle of the bladder contracts, the external sphincter may spasm and stay closed, rather than relax and allow urination. The opposing contractions cause pressure in the bladder to rise dangerously and result in the serious condition of being unable to empty your bladder. |
