The model was completely closed and the only backflow was on the side of the ureteroscope inside the ureteral access sheath (UAS). We tested five single\u2010use f\u2010URSs (LithoVue, Wiscope, PU3022A, PU3033A, and AXIS) with six different types of UAS (9.5\/11.5\u201314\/16 Fr). Using the automatic irrigation system, 30\u2009s of irrigation was performed at various pressures (40\u2013180\u2009mmHg) and steady\u2010state IPP was recorded. IPP was compared between the five single\u2010use f\u2010URSs. IPP cutoff value was determined at 30\u2009mmHg. The diameter of the endoscope tip and the curved and shaft parts were also measured and recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The diameters of all parts were significantly different between single\u2010use f\u2010URSs.

In LithoVue and Uscope PU3022A f\u2010URSs, the maximum IPP did not exceed 30\u2009mmHg when UAS \u226512\/14 Fr was used. In AXIS and Wiscope f\u2010URSs, it did not exceed the cutoff value when the UAS \u226511\/13 Fr was used.
