Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This research is studying Definity ultrasound contrast agent, which is already approved by the Food and Drug Administration (FDA) for the ultrasound evaluation of the liver and heart. This research will investigate the ability to use ultrasound imaging with ultrasound contrast agents to evaluate kidney obstruction. Eligible participants that are enrolled will have two visits (one before and one after the planned surgery to relieve the kidney obstruction).
