What Guidewire Is the Best for Bypassing an Impacted Ureteral Stone?

Abstract

Introduction and Objectives: To determine the optimal guidewire for bypassing an impacted ureteral stone. Materials and Methods: Three different benchtop models of varying impaction (300, 362, and 444?mm Hg pressure) were used to compare the ability of 13 different guidewires to bypass an impacted ureteral stone. In the first and second models, we recorded the maximum force required to bypass the stone. In the first model (300?mm Hg) 10 new wires for each of the 13 types were advanced past a ureteral stone using a series 5 digital force gauge. In the second model (362?mm Hg), the top 5 performing guidewires were similarly tested. In the third model (444?mm Hg), 5 attending urologists and 5 urology residents (blinded to wire type) compared the 13 guidewires and rated the wire performance using a Likert scale. Statistical analysis was performed with analysis of variance and the chi-square test. Results: In the first model, there was a significant difference between wires (p?
