Could bladder wall elastography be used as an indicator for the diagnosys of bladder outlet obstruction by benign prostate hyperplasia?

Abstract

Benign prostatic hyperplasia (BPH) is one of the most common causes of bladder outlet obstruction in men. In this study we aimed to evaluate the elasticity of the bladder by Acoustic Radiation Force Impulse (ARFI) elastography in BPH patients. Fifty benign prostate patients were included in the study. After evaluation of patients in the outpatient clinic. A RFI elastography was performed with full bladder. Elastography was performed separately on the anterior, right and left walls of the bladder. Then the patient underwent uroflowmetry. The maximum flow rate and post-mix residual values in uroflowmetry were recorded. The mean age of the patients was 45.6 ± 3.77 The average of bladder anterior wall elasticity 3.39 ± 0.89, Bladder left wall elasticity 2,69 ± 0,82 and Bladder right wall elasticity was 3.69 ± 0.89.The mean prostate size 52.58 ± 24.16 The average of Qmax11.96 ± 4.85 The mean of PMR 77.8 ± 59.6 and mean of prostate elasticity was 2.97 ± 1.1 Urinary bladder wall elasticity with ARFI can be a diagnostic indicator for bladder outlet obstruction due to BPH.
