Endoscopic Valves and Irrigation Devices for Flexible Ureteroscopy: Is There a Difference?

Abstract

A variety of ureteroscopic irrigation systems are available, ranging from gravity-driven pressure bags to hand-operated pumps. Endoscopic valves maintain a watertight seal during ureteroscopy (URS) while facilitating passage of instruments. The clinical utility and ergonomics of such devices have not been established. We systematically compare the mechanical properties and usability of select valve devices and hand-operated irrigation systems in an in vitro setting. In vitro testing of four different endoscopic valves: UroSeal adjustable endoscopic valve (US Urology), adjustable biopsy port seal (Gyrus ACMI), Blue Silicone Seal ACMI CS B612 (Gyrus ACMI), and REF ABP Biopsy Port Seal (ACMI Corporation) was performed. Usability was evaluated via insertion/extraction forces and insertion time for instruments, including a straight tip sensor wire, 0.035″, (Boston Scientific), a laser fiber (Flexiva 200, Boston Scientific), and an Ngage Nitinol Stone Extractor 1.7F (Cook Urological) through a flexible ureteroscope (Olympus URF P5, Olympus). Flow rate, flow time, and user fatigue were tested for two irrigation systems: The single action pumping system (SAP, Boston Scientific) and the Pathfinder Plus (PP, Utah Medical Products). The U...Continue Reading

Actin-binding Proteins

Actin-binding proteins are a component of the actin cytoskeleton that play essential roles in cellular functions such as regulation of actin polymerization, maintenance of cell polarity, gene expression regulation, cell motility and many more functions.
