Silhouette Ureteral Stents Clinical Studies

Resistance to Extrinsic Compression and Maintenance of Intraluminal Flow in Coil-Reinforced Stents (Silhouette Scaffold Device): An In Vitro Study.

Journal of Endourology. April 2010

Miyaoka R, Hendlin K, Monga M.

Excerpt:

"The resistance of 8 F Silhouette Scaffold Device is extremely higher than that of previously tested stents, and it is uniform along the shaft and does not vary with length. The Cook Amplatz 10.2 F stent has higher flow at baseline and 2mm compression, but its flow rate drops four times faster than the Silhouette Scaffold."

Analysis of Ureteric Stent Kinking Forces: The Role of Curvature in Stent Failure.

Published:

British Journal of Urology International. 2009 September

Authors:

Christman MS, L'Esperance JO, Choe CH, Stroup SP, Auge BK.

Excerpt:

"The greater allowable curvature and resistance to kinking achieved by the Silhouette ureteric stents might result in fewer stent failures in cases of malignant obstruction or other retroperitoneal processes."

Analysis of Ureteral Stent Compression Force and Its Role in Malignant Obstruction.

Published:

The Journal of Urology. 2009 January

Authors:

Christman MS, L'esperance JO, Choe CH, Stroup SP, Auge BK.

Excerpt:

"The Silhouette 4.6Fr, 6Fr and 8Fr ureteral stents, and the Resonance 6Fr stent had significantly greater resistance to compression than all of the other stents tested. Patients with malignant ureteral compression may benefit from the use of these wire reinforced stents."

Wire-Based Ureteral Stents: Impact on Tensile Strength and Compression.

Published:

Urology. August 2007

Authors:

Pedro RN, Hendlin K, Kriedberg C, Monga M.

Excerpt:

"Both the Cook Resonance and Applied Medical Silhouette stents are more resistant to extrinsic stent compression than ureteral stents that are not coil-reinforced. The Cook Resonance has a higher tensile strength, whereas the Applied Medical Silhouette is more resistant to extrinsic compression."
