when there is interference with the sequence of these three degrees of the voiding need , especially the absence of the sensation normally contemporaneous with the detrusor action or immediately preceding it , there is exaggeration of either the hyperactivity or the hypoactivity of the bladder , and this aggravates vesical sensitivity : premature contraction of the detrusor muscle eliminates the first two degrees ( usual need and pressing need ) , while progressive distension of the detrusor muscle eliminates all three stages .
