JVIR CME October 2022

This month’s journal-based CME article is titled "Comparison between antegrade versus retrograde ureteral stent placement for malignant ureter obstruction". This is a single-center, retrospective study of all de novo ureteral stent placements in the setting of malignant ureteral obstruction. After applying the exclusion criteria, a total of 137 procedures in 99 patients were evaluated. The authors then compared the techniques of antegrade ureteral stent placement (AUS) with those of retrograde ureteral stent placement (RUS).

The goal of this article is to help interventionalists understand what the high clinical and technical success rates for antegrade ureteral stenting in malignant ureteral obstruction. This study highlights the impact on theoretical cost by using a DCB in the maintenance of hemodialysis access fistulas.

This program is designed to meet the educational needs of interventional radiologists, nurses, techs, and trainees at all levels with special interest in treatment of patients with malignant ureteral obstruction. To receive CME credit for this journal-based CME activity, participants must read the journal article and score 75% or better on the post test. Participants will have three opportunities to score 75% or better.

Learning Objectives

After participating in this journal-based CME activity, learners should be able to:

• Discuss technical success rates of antegrade ureteral stenting.
• Understand technical difficulties of retrograde stenting
• Described clinical success rates of ureteral stenting.
