Bladder outlet obstruction: progression from inflammation to fibrosis

Abstract

With this model, we have effectively replicated the clinical scenario, with significant pathophysiological changes occurring insidiously in otherwise healthy rats. We believe that our observed changes represent distinct phases of bladder decompensation; with an initial inflammatory response to the stress of the pBOO, smooth muscle hypertrophy to overcome the increased urethral resistance, and eventual decompensation to fibrosis. The time course of the inflammatory markers implies the need for early intervention to prevent this cascade. Novel strategies targeting these observed physiological responses could lead to improved preventative strategies, with respect to biochemical pathways and the time course of their initiation.
