Study Summary
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.
Primary Outcome
Shear wave velocity VTQ, or Virtual Touch Quantification is a "point" method for measuring a tissue's stiffness. A stiffness value is obtained from only the area in which a region of interest is placed.
Interventions
- DEVICE ARFI-Derived Shear Wave Velocities
