Intrarenal pressure variations during flexible ureteroscopy in a porcine kidney model: impact of ureteral access sheath types and irrigation methods.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo evaluate intrarenal pressure (IRP) variations during flexible ureteroscopy (f-URS) using flexible and navigable suction (FANS) ureteral access sheath (UAS) and conventional UAS (c-UAS) and irrigation methods.
methodsA fresh cadaveric porcine kidney model was used to measure real-time IRP during f-URS via a pressure transducer connected to a ureteral catheter placed in the renal pelvis. FANS and c-UAS were evaluated with three irrigation methods: gravity-based, hand pump-assisted, and machine irrigation (MI) with and without suction.
resultsThe combination of MI with suction and FANS resulted in the lowest IRP (1.7 ± 0.6 cm H₂O), significantly outperforming other methods (p < 0.001). The highest IRP was observed with MI in conjunction with c-UAS (39.6 ± 0.8 cm H₂O). Gravity-based and pump-assisted irrigation with c-UAS yielded moderate IRP levels (16.1 ± 0.5 cm H₂O and 22.3 ± 1.9 cm H₂O, respectively). Statistical analysis revealed that both the type of UAS and irrigation method significantly affected IRP (p < 0.001), with a notable interaction effect between the two variables.
conclusionThe combination of FANS and MI with suction provides superior IRP control during f-URS, substantially reducing pressure compared to c-UAS. C-UAS with MI can result in elevated IRP levels. These findings underscore the importance of selecting appropriate irrigation methods and UAS to minimize IRP-related complications during endourological procedures.
