Abstract
Bladder is a complex organ and its proper function is closely tied to the mechanobiology of its multi-layer wall. Characterization of the bladder wall mechanical properties is crucial in diagnosis of diseases that can lead to lower tract infection and incontinence. Ultrasound bladder vibrometry has emerged as a noninvasive method for characterization of the bladder tissue elasticity using Lamb wave model (Nenadic et al. PLOS 2016). Previous studies have shown an increasing trend in bladder elasticity with added fluid which is an indication of a nonlinear behavior. In this study, we use the acoustoelasticity (AE) theory to quantify the bladder tissue nonlinearity parameter A. We show that this parameter can precisely differentiate between the intact and aberrant ex vivo bladder samples treated with formalin.
