Hydronephrosis ARFI Study

Not Applicable

Completed

• Conditions: Hydronephrosis
• Interventions: Procedure: AFRI-SVI Ultrasound

• Registration Number: NCT01781845
• Lead Sponsor: University of Michigan

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.

Arm && Interventions

Group	Intervention	Description
ARFI-SVI Ultrasound	AFRI-SVI Ultrasound	Ultrasound scan using acoustic radiation force impulse-shear wave velocity imaging in the characterization of pediatric hydronephrosis. This is a non-invasive scan that uses sound waves to create the images.

Primary Outcome Measures

Name	Time	Method
ARFI-SVI	6 months	fibrosis and intratubular pressure will be evidenced by higher parenchymal shear wave velocity measurements using the ARFI-SVI technology.
