Load-release points of two novel ureteral stone-trapping devices.

Purpose: We compared the load-release points of the Stone Cone and the new Cook Urological NTrap devices using an in vitro model of the ureter.

Materials And Methods: A strictured-ureter model was created using urethane tubing with a wire tie around it. A plastic bead was lodged above this narrowing.

Assessment of novel ureteral occlusion device and comparison with stone cone in prevention of stone fragment migration during lithotripsy.

Purpose: To present the initial ex-vivo results of a new ureteral-occlusion device (Cook Urological, Spencer, IN) for preventing the retrograde migration of particles during ureteroscopy and its comparison with the Stone Cone (Microvasive-Boston Scientific Corp., Spencer, IN).

Materials And Methods: We designed an ex-vivo model using a porcine kidney with an intact ureter.

Primary malignant mesothelioma of the penis: case report and review of the literature.

We present an unusual case of primary malignant mesothelioma of the penis in an adult male. The clinical features and microscopic, immunohistochemical, and ultrastructural characteristics that help to identify this entity are described. A discussion of the behavior of malignant mesothelioma follows, as well as a possible explanation for its origin in the penis.
