A single center study that evaluates the preclinical use of a newly developed software and moving bed system to facilitate the spontaneous excretion of residual fragments after primary stone treatment (RIRS or PCNL).
Article in World journal of urology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
purposeWe developed a Postural Drainage Lithotripsy System (PDLS) that uses the patient's computed tomography urography (CTU) data to reconstruct the three-dimensional figure of the renal pelvis, provides an individualized inversion and overturning angle and uses gravity to remove residual fragments (RFs). The purpose of this study was to investigate PDLS in the treatment of renal RFs.
methodsA stone with a diameter of 4.0 mm was placed in the upper, middle, and lower calyx of the renal model. A total of 60 trials were applied to 20 renal models. The movement trajectory, passage rate, and postural drainage angle of calculi during the treatment of PDLS were observed.
resultsAll of the stones in 60 trials were observed to move during treatment, and 53/60 (88%) were relocated successfully to the renal pelvis. The passage rate of the upper calyx was 14/20 (70%), that of the middle calyx was 20/20 (100%), and that of the lower calyx was 19/20 (95%).
conclusionsPDLS can provide individualized inversion and reversal angles and remove stones from the renal model. More clinical trials are needed to verify the above view and evaluate its efficacy.
