A novel protocol for the characterization of ureteral stent echogenicity.

Background: Decreasing radiation exposure in renal colic management involves revisiting diagnostic, intraoperative, and postoperative practices. One approach is a shift in procedural standards from intraoperative fluoroscopy to ultrasonography. Despite the increased implementation of ultrasound in urology, the ultrasound visibility or echogenicity of various stents is not well-studied.
