Patients who have been diagnosed with obstructive uropathy


Inclusion Criteria:

  • Males or females 18 years of age or older.
  • All female patients of childbearing potential must agree to use a medically accepted method of contraception at the time of the study.
  • Patients must have the ability to understand the requirements of the study, provide written and informed consent to participate, and agree to abide by the study requirements.
  • Patients who have known or suspected hydronephrosis or patients with solitary kidneys.

Exclusion Criteria:

  • Patients with known or suspected hypersensitivity to gadolinium-based agents.
  • Patients who are pregnant or lactating.
  • Patients with a condition that is a contraindication to MRI (e.g., cardiac pacemaker, epicardial pacemaker leads, cochlear implants, ferromagnetic aneurysm clip, ferromagnetic halo device, or other conditions that would preclude patient proximity to a strong external magnetic field).
  • Patients with a recent history of hemolytic anemia, sickle cell anemia or other hemoglobinopathy.
  • Patients with a history of significant claustrophobia.
