S. Kim, B. Matlaga, M. Jackson, R. Kuo, J. Williams, Jr., J. McAteer, and J. Lingeman. (J. Urol 173: Abst. 1576. May 25, 2005)

In this in vitro study, a prototype dual, concentric probe, ultrasound unit outperformed the combined single ultrasound/pneumatic Lithoclast Ultra unit. Using a gypsum artificial stone, the Cyberwand produced penetration times that were 41% faster. Clinical trials pend.

Flow Characteristics of Two Ipsilateral and Novel Ureteral Stents: How Well Do They Provide Relief of Ureteral Obstruction?

D. Tan, J. Hafron, D. Hoenig, B. Lee, and A.Smith (J. Urol 173: Abst. 1577. May 25, 2005)

A novel dual lumen 7F stent provided drainage nearly 4-5 fold better than a standard 7F stent in an ex vivo porcine model of ureteral obstruction. Indeed, the flow rate was similar to that obtained in an obstructed ureter with two, standard 7F stents placed. Development of a stent of this nature could prove to be of great value to the patient population afflicted with malignant ureteral obstruction.
