Summary
The investigators propose a new imaging method for children born with congenital anomalies of the urinary tract that is a rapid, injection-, sedation-, and radiation-free alternative: the quick renal MRI. This proposal hypothesizes that the quick renal MRI has high validity compared to current radiologic standard for renal infection and scarring, the 99mTechnetium-dimercaptosuccinic acid (99mTc- DMSA) renal scan in the detection of acute renal infections and scars. If the quick renal MRI is accurate, it could potentially replace the DMSA scan for those specific questions and ease the burden of testing for children with chronic renal disease. Findings from these studies will provide preliminary data and rationale for a multi-centered study to further test this new technology.
Participants will be 0-21 years of age and can expect to be on study for from 1 week (if enrolled in Aim 1) to 6 months (if enrolled in Aim 2).
Description
Children born with congenital anomalies of the urinary tract are susceptible to kidney infections and scarring. They form a high risk group for developing renal insufficiency in adulthood. A basic tenet in pediatric urology is that kidney infections should be prevented and otherwise promptly identified to minimize the risk of acquiring renal scars and permanent tissue damage.
The current radiologic standard for renal infection and scarring is the 99mTechnetium-dimercaptosuccinic acid (99mTc- DMSA) renal scan. This exam requires an intravenous injection, occurs over a 3 hour period, involves exposure to radiation, and can require sedation of young children. The investigators propose a new imaging method that is a rapid, injection-, sedation-, and radiation-free alternative: the quick renal MRI. This proposal hypothesizes that the quick renal MRI has high validity compared to the DMSA scan in the detection of acute renal infections and scars. If the quick renal MRI is accurate, it could potentially replace the DMSA scan for those specific questions and ease the burden of testing for children with chronic renal disease. Findings from these studies will provide preliminary data and rationale for a multi-centered study to further test this new technology.
There are two separate aims to this study, and study activities/schedule will vary depending on which aim the participant is in:
Aim 1: Inpatients presenting with acute pyelonephritis or possible acute pyelonephritis will be approached about the study. After participant's consent to the study, they will complete a clinical DMSA scan and quick MRI for the study. The DMSA scan and quick MRI will be completed within one week of each other, and ideally during the participant's inpatient stay.
Aim 2: Patients presenting to clinic for visits regarding their renal scarring will be approached about the study. If participant's consent to the study and if possible, they will schedule the quick MRI during this visit. The clinical DMSA scan and quick MRI should be completed within 6 months of each other for this patient population.
