Comparison of 3 Upper Tract Anticarcinogenic Agent Delivery Techniques in an Ex Vivo Porcine Model

Our results suggest that retrograde infusion via open-ended ureteral catheter is the most efficient method of upper tract therapy delivery. Larger studies using in vivo models should be performed to further validate these findings and potentially confirm this method as optimal for delivery of topical anticarcinogenic agents in upper tract urothelial carcinoma.
