Abstract No. 571 EW-7197–eluting nano-fiber covered self-expandable metallic stent to prevent granulation tissue formation in a canine urethral model

The purpose of this study was to evaluate an EW-7197–eluting nanofiber-covered stent (NFCS) for granulation tissue formation after stent placement in a canine urethral model. All experiments were approved by the committee of animal research. A total of 12 NFCSs were placed in the proximal and distal urethras of six dogs. Dogs were divided into two groups with 3 dogs each. The control stent (CS) group received NFCSs and the drug stent (DS) group...
