title: Effect of mucosal resection on detrusor function in the disused rabbit bladder.
abstract: A new rabbit model of disused bladder was developed. Disused bladders were created by sagittal splitting of the bladders along the midline and closure of one side (reservoir side), leaving the remaining side unclosed (disused). The mucosa was dissected from some of the disused sides. Tissue elasticity and the weight of the detrusor muscle were decreased by bladder disuse. The responsiveness to field stimulation, bethanechol, ATP, KCl, or isoproterenol, was decreased by disuse. Tissue elasticity and responsiveness to stimuli were decreased to a lesser extent in disused tissue with intact mucosa. Results suggest that the bladder mucosa helps to preserve the function of the disused bladder.
