Primary Outcome Measures:
  • To assess the value of a rapid noncontrast MRI not requiring sedation to ultrasound in accurately diagnosing hydronephrosis in the pediatric patient. [ Time Frame: 45 minutes ]
    A rapid MRI exam will be performed without IV contrast material or sedation


Enrollment: 0
Study Start Date: February 2012
Estimated Study Completion Date: January 2018
Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: MRI
The patient will have a rapid noncontrast MRI (magnetic resonance imaging) that will take approximately 15 minutes to complete.
Procedure: MRI (Magnetic resonance imaging)
Subject will complete a 15 minute scan in the MRI
Active Comparator: Ultrasound exam
A noncontrast ultrasound examination
Procedure: Ultrasound exam
The subject will complete a noncontrast ultrasound procedure that will take approximately 25 minutes to complete

Detailed Description:

Ultrasound is the most commonly performed imaging modality used to assess hydronephrosis. The average renal ultrasound exam takes about 15-25 minutes to complete, however, it does have several disadvantages, including substantial operator dependence, having to rely on an adequate "sonographic window" to see the structures of interest and difficulty in visualization of portions of the kidney and urinary tracts.

Recent MRI advances have made rapid imaging possible. Such imaging has minimized motion related artifacts and need for sedation.

This study is to compare traditional ultrasound imaging to a raid noncontrast protocol MRI examination of the kidneys and urinary tract that would require no sedation and less than 15 minutes to perform.
