Abstract

To understand the urographic findings relating to diseases of the prostate, it is necessary to be aware of the response of the bladder and upper urinary tract to outlet obstruction. Whatever the etiology of obstruction of urine outflow from the bladder, the detrusor of the bladder compensates by hypertrophy, In the early stages, much as occurs with the heart, functionality of the bladder is maintained by increased contractility. As muscular hypertrophy progresses, there is resultant thickening of the bladder wall, including the trigonal region. With increasing intraluminal pressure, the bladder mucosa begins to herniate between the thickened muscle bands of the wall. Small mucosal herniations that do not protrude beyond the bounds of the bladder are known as cellules. With persistent obstruction these progress to frank bladder diverticula. Not being invested with a muscular coat, these diverticula do not empty well at voiding, and in fact may increase their volume.
