Study Type: Interventional

Official Title: Evaluation of Ultrasound Acoustic Radiation Force Impulse (ARFI)Shear Wave Velocity Imaging (SVI)in the Characterization of Pediatric Hydronephrosis

Brief Summary: Pediatric upper urinary tract dilatation (hydronephrosis) is relatively common and may be either obstructive or nonobstructive. While the upper urinary tract is commonly evaluated by ultrasound, this imaging technique often fails to distinguish obstructed from nonobstructed systems. ARFI SVI is a new ultrasound technology that can be used to determine stiffness by measuring a tissue's shear wave velocity, may show alterations in parenchymal shear wave velocity in kidneys that show obstruction on DRS (Diuretic renal scintigraphy)which serves as the reference standard.

Detailed Summary:
Sponsor: University of Michigan

Current Primary Outcome: ARFI-SVI [ Time Frame: 6 months ]

fibrosis and intratubular pressure will be evidenced by higher parenchymal shear wave velocity measurements using the ARFI-SVI technology.


Original Primary Outcome: Same as current
