We aimed to assess if in vitro it could reduce intrarenal pressure (IRP) and increase irrigant flow compared to traditional UASs. METHODS: A validated phantom kidney with fibre optic pressure sensing capabilities was used to assess the IRP. Standardised 80 cmH2O irrigation via a ureterorenoscope was instilled through traditional UASs (11/13 and 12/14 F) and compared to the novel 11/13 F syphoning UAS. The measured minute volume, calculated hourly flow volume, and steady state IRP were compared. RESULTS: The traditional 11/13 and 12/14 F UASs had statistically poorer irrigant flow than the novel syphoning UAS, at 19.3 vs. 29.3 mL/min (P <0.001AQ5) and 22.7 vs 29.3 mL/min (P=0.002), respectively. The steady state IRP was 20 mmHg for the traditional 11/13 F and 13 mmHg for the 12/14 F compared to 0 mmHg for the novel UAS. CONCLUSIONS: The described novel UAS is different from traditional devices by incorporating a syphon mechanism. Our in vitro assessment demonstrates that the novel UAS holds clinical potential to reduce IRP while allowing a significant increase in irrigant flow compared to larger diameter traditional UASs.
