title: The radiological and urodynamic significance of large bladder diverticula.
abstract: Large acquired bladder diverticula in adults may cause severe urodynamic disturbance and exacerbate difficulty in micturition. They may accommodate a large proportion of the contents of the bladder during attempted voiding, thus decreasing the effect of the detrusor muscle contraction. The post-micturition radiographs on intravenous urography, after the diverticula have emptied again, may only show a large intravesical post-micturition residue and give little information as to the size of the diverticula during the act of micturition.
