LVE was used in a porcine model to measure intrarenal pressure with and without a ureteral access sheath (UAS) with various sizes and placement locations, irrigation methods, and working channel accessories. LVE pressure accuracy was measured in a bench model. This abstract shows the least-square means from multiway analysis of variances used for analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Intrarenal pressures were the highest without a UAS (64\u2009mm Hg), followed by the 11\/13 UAS (51\u2009mm Hg) and the 12\/14 and 13\/15, which were not statistically different (39\u201340\u2009mm Hg). The pressures were highest with UASs placed at the ureteropelvic junction (61\u2009mm Hg), and lowest if placed in the renal pelvis (24\u2009mm Hg). Irrigation methods showed the highest pressures with syringe (57\u2009mm Hg), while irrigation bags (pressurized at 150\u2013300\u2009mm Hg) produced 43 to 46\u2009mm Hg and 25\u2009mm Hg when applied with 80\u2009cm of gravity. Placing a 200\u2009\u03bcm laser fiber reduced pressures from 44 to 41\u2009mm Hg. Finally, the bench model showed that LVE was 96% accurate up to 300\u2009mm Hg.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Intrarenal pressure significantly varied based on UAS sizes, placement, and irrigation methods.
