The Pathophysiology of Large Capacity Bladder

Abstract

The etiology of large capacity bladder is multifactorial and often a potentially remediable underlying condition exists. A large capacity bladder may be accompanied by bladder outlet obstruction, impaired or absent detrusor contractions, or normal detrusor pressure/uroflow studies. When detrusor contractions are present, they usually occur only at large bladder volumes. Therefore, it is important during cystometry to fill the bladder until capacity is achieved.
