Contrast-enhanced Ultrasound for the Evaluation of Complex Renal Cysts
By evaluating complex renal cysts using a contrast-enhanced ultrasound (CEUS), it can be
established as to whether or not the results are better, the same, or worse, when compared
to CT and/or MRI scans.
Allocation: Non-Randomized, Intervention Model: Single Group Assignment, Masking: Single Blind (Outcomes Assessor), Primary Purpose: Diagnostic
concordance between CEUS and CT
Complex renal cysts will be classified using the Bosniak classification system for both the CEUS and CT and compared. If surgical removal of a complex cyst is required (Bosniak IIF, III or IV), then the pathology will be evaluated with a single CEUS and a CT (The CEUS will be conducted 14 days within the CT).
