About

Urinary bladder fibrosis (thickening and scarring) is fairly uncommon in children. Traditionally, the presence of urinary bladder fibrosis has been confirmed directly with bladder biopsy or using urodynamic testing. In this study we will use ultrasound scanning and ARFI (acoustic radiation force impulse) wave velocities to potentially identify any urinary bladder wall fibrosis.

Full description

Urinary bladder fibrosis (thickening and scarring) is fairly uncommon in children. Traditionally, the presence of urinary bladder fibrosis has been confirmed directly with bladder biopsy or using urodynamic testing. We will use ultrasound ARFI (acoustic radiation force impulse)-derived shear wave velocities to potentially identify the presence of urinary bladder wall fibrosis. We hypothesize that shear wave velocities found within the bladder wall will increase with increasing evidence of fibrosis.

(ARFI)-Derived Shear Wave Velocities
Experimental group
Description:
This is an ultrasound-based new technique using Acoustic Radiation Force Impulse (ARFI). Shear Wave speeds are derived using ARFI. During ultrasound scanning a sound wave is sent towards tissue. The tissue's movement in response to the wave is measured in Shear Wave Velocity, which can estimate tissue stiffness. This technique may help detect bladder wall thickness and fibrosis (thickening) in the urinary bladder of pediatric patients.
