Is Collagen Remodeling Associated with Bladder Obstruction?

  • H. Paul Ehrlich
Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 385)


Collagen, proteoglycans and elastin combined with resident smooth muscle cells (SMC) makeup the basic structural unit of the bladder wall. Any pathologic process that alters either the content or organization of collagen within the bladder wall will modulate the ability of the bladder to store urine or efficiently empty itself (1). An obstruction that develops at the outlet of the bladder results from a narrowing of that lumen. There are numerous physiological and anatomical possibilities for producing the constricture of that lumen. In some constrictures it is proposed that connective tissue remodeling is critical in causing the narrowing of the lumenal space in the bladder outlet.
