Does instrumentation and irrigation configuration affect intrarenal pressure during PCNL?
Article in BJUI compass, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Objectives: To measure the effects of varying configurations of nephroscope sheath, irrigation, instruments, and suction on intrarenal pressure (IRP) during percutaneous nephrolithotomy (PCNL). Materials and Methods: Kidney and ureter 3D printed models from a deidentified patient's CT scan were placed in a plaster and foam mould, simulating the torso of a prone patient. An Amplatz sheath was inserted into the kidney model. Fourteen different rigid nephroscope sheath (RNS), irrigation, instrument and suction configurations were compared. IRP was measured in a retrograde fashion. Comparisons were performed using the Wilcoxon Signed-Rank test followed by Bonferroni correction. Results: The mean IRP with and without the RNS was 19.1 and 14.7 mm Hg, respectively ( Conclusion: In situations where the IRP should be low, removal of the RNS, irrigating through the inflow port, and frequent use of suction maintain the lowest pressures. If temporary increases in IRP are necessary to improve visualisation in the setting of bleeding, irrigating through the outflow port, minimising drainage and use of the RNS can be used to raise IRP.
