Brief Summary:
Urine reflux (urine backing up into the kidneys) is common in the pediatric population and may be complicated by renal abnormalities, such as infection and scarring. Currently, urine reflux is detected using either voiding cystourethrogram or other procedures. A new technique called ultrasound-based Acoustic Radiation Force Impulse (ARFI), or shear wave velocity imaging SVI) is performed using standard approved ultrasound machines and transducers bu the sound waves/impulses are produced in a different pattern. We hope to evaluate the usefulness of ARFI in diagnosing possible kidney damage caused from urine reflux (urine backing up into the kidneys).

Arm Intervention/treatment
Experimental: ARFI SVI ultrasound imaging
Acoustic Radiation Force Impulse (ARFI) Shear Wave Velocity Imaging (SVI) ultrasound imaging
Procedure: ARFI SVI Ultrasound Imaging
Following a clinical renal ultrasound scan, the research scan using the ultrasound based acoustic radiation force impulse, or shear wave velocity imaging will be performed using standard approved ultrasound machines and transducers. This imaging will take approximately 5 to 10 minutes to complete.



Primary Outcome Measures :
  1. Ultrasound-Based Acoustic Radiation Force Impulse(ARFI)Shear Wave Velocity Imaging (SVI) [ Time Frame: 6 months ]
    To determine if this new ultrasound based imaging will effectively measure shear wave velocity in kidneys affected by urine reflux and be useful in determining the extent of kidney damage
